Abstract In coffee breeding, selection of mother plants based on the yield potential, resistance to diseases and pest and bean quality are considered as the important criteria. Hence, utilisation and evaluation of coffee germplasm is the crucial step in the improvement process. With this background, an experiment was conducted to study the genetic diversity of 41 Arabica coffee genotypes in India during 2020–2021 and 2021–2022. Study reveals that, the analysis of variance revealed significant differences among the genotypes for all the characters studied indicating the presence of variability. Relatively higher values for GCV were observed for number of secondaries per primary (29.77 and 24.84%), total nodes per primary (30.07 and 26.62%), bearing nodes per primary (35.72 and 29.03%), number of flower buds per primary (40.79 and 33.68%), number of fruits per primary (49.64 and 36.39%) and per cent ‘A’ grade bean (37.47 and 37.83%) than PCV indicating the influence of environmental variations is less and prevalence of additive gene action. Similarly, high magnitude of heritability (>80%) combined with a strong genetic advance as per cent of mean (>20%) was established for most of the growth and yield attributing traits including caffeine content and per cent ‘A’ grade bean (100%) during both the years of study 2020–2021 and 2021–2022, respectively indicated better scope for genetic improvement in these character through simple selection. The variability observed among the genotypes should be further confirmed by using the molecular markers.

Abstract Jujube is both consumed as a food source and medicinal plant in local markets. It is expected that different geographical populations of Ziziphus jujuba , differ in their genetic content as they grow in different ecological conditions. It is important to have detailed information on population genetic structure and the available genetic variability to make a proper germplasm collection of jujube. We have no data on jujube populations of Iran based on SCoT and REMAP molecular markers, and therefore we planned a population genetic study of these trees in 10 geographical areas. We used SCoT and REMAP molecular markers for our genetic investigation. We found the loci with a high value of Gst (1.00) in SCoT and REMAP markers that can be used in fingerprinting of jujube.

Abstract The lack of excellent wheat germplasm resources on the Qinghai-Tibet Plateau has led to a gradual decrease in genetic diversity and an increasingly narrow genetic background in wheat grown in this region. Rational use of excellent genes from wheat relatives is important to increase genetic diversity, broaden the genetic base and achieve high yield and quality in common wheat. The objective of this study was to use principal component and cluster analyses of 13 important agronomic traits of 44 Polish wheat varieties over 3 years and comprehensively evaluate them to screen for excellent germplasm resources, thus providing the basic material for broadening the genetic base of Qinghai-Tibet Plateau wheat germplasm resources.

To explore trait variation, assess relative performance and establish association among yield and its associated traits in maize under organic system, 373 maize genotypes that consisted of landraces, open-pollinated varieties and single-cross hybrids were tested under organic management in Sikkim midhills. Data of 8 years (2009–2015 and 2019) for 12 agronomic traits viz., plant height, days to 50% tasselling, days to 50% silking, days to 75% dry husk, grain yield per ha, anthesis–silking interval, cob length, cob diameter, kernel rows per cob, kernels per row, number of cobs per plot and test weight were taken for analysis. Conventionally bred maize hybrids yielded 95.36% higher than the landraces and 58.60% higher than the open-pollinated varieties. Landraces displayed highest mean anthesis–silking interval of 7.18 days. In open-pollinated varieties, test weight showed a positive association with grain yield (0.37) while plant height (0.33) and kernels per row (0.34) were positively correlated to grain yield in case of landraces. Number of cobs per plot showed a very strong association with grain yield in hybrids (1.0). Kernels per cob and test weight contributed 24% to the variation in grain yield in open-pollinated varieties while anthesis–silking interval, days to maturity, number of cobs/plot, test weight and kernel per row accounted for 97% of the variation in grain yield in landraces. Grain yield in single-cross hybrids is contributed maximum (97%) by days to tasselling, silking, anthesis–silking interval, plant height and number of cobs per plot. The study indicates attaining high number of cobs per unit area along with emphasis on traits such as kernels per row, cob length and diameter for achieving higher yields in single-cross hybrids, selection of high test weight genotypes for open-pollinated varieties and emphasis on cob length, kernels per row and plant height for yield improvement in landraces.

Microsatellite primers are a valuable tool to use for both observational and experimental studies in numerous taxa. Here, we develop 18 and 16 microsatellite markers for the widespread duckweeds Lemna minor and Spirodela polyrhiza, respectively. Only four primers were not polymorphic when tested on samples from Europe and Western Pennsylvania, USA.

Landraces are traditional crop varieties that often have special adaptations to the farming environment in which they have evolved and are therefore a valuable source of useful traits for plant breeders. In most agriculturally advanced countries, landraces of the main crops have generally been superseded by modern varieties. An exception to this in the United Kingdom is the cultivation on the Scottish archipelagos of Orkney, Shetland and the Outer Hebrides of three cereal landraces: bere, a 6-row barley (Hordeum vulgare), small oat (Avena strigosa) and Hebridean rye (Secale cereale). Our study focused on trends in their cultivation and use over the past 20 years. In the Outer Hebrides, a mixture of all three has continued to be grown on more than 200ha for feed because of its tolerance of nutrient-deficient sandy soils. Future cultivation is threatened, however, by damage from geese and deer, especially to fields used for seed production. In Orkney and Shetland, only bere and small oat are grown, and always as sole crops. The area of bere has increased in Orkney, from about 10ha in 2004 to almost 75ha in 2020 and has been driven by two supply chains producing bere for milling and malting. However, small oat in Orkney, and both small oat and, especially bere, in Shetland have been grown by very few farmers since 2018 and are at serious risk of being lost from cultivation. We discuss these results in the context of measures to support greater on-farm cultivation of these landraces.

A total of 366 accessions of okra (Abelmoschus esculentus (L.) Moench) obtained from the Agricultural Plant Genetic Resources Conservation and Research Centre (APGRC) in Sudan were characterized for a number of morphological characters using a descriptor list derived from the list published by the International Board for Plant Genetic Resources in 1984. Those accessions, which were collected from different regions of Sudan, were grown in the APGRC research farm in Wad Medani town in central Sudan during ten different seasons within the period between 2000 and 2019. Phenotypic variations were observed among and within the different accessions for plant, stem, leaf, inflorescence and fruit characters. Up to 59% of accessions were found to be heterogeneous for different traits. The descriptor states observed ranged from very rare in 5%or less of the accessions, to abundant in more than 90% of the accessions. Substantial phenotypic variation was observed for okra fresh fruits, the main organs used for food, in terms of shape, colour, pubescence and number of ridges. Accessions carrying fruits preferred in local or foreign markets were identified making them good candidates for further breeding to produce new cultivars for both markets. The cluster analysis resulted in 13 subclusters at a similarity level of 60%. When comparing the subclusters with collection sites, no direct relation was detected indicating that okra germplasm has been spreading all over the country resulting in diversified materials across different regions.

Native livestock breeds are part of the history of the Nordic people and comprise a resource for future food production. In this study, net gain and carcass characteristics of two Danish, three Finnish, one Icelandic, six Norwegian and five Swedish native cattle breeds were retrieved and compared to commercial breeds: two beef breeds and two dairy breeds. Breed data were collected from national databases and sorted into six animal categories: young bull, bull, steer, heifer, young cow and cow, for which means and standard deviations were calculated within each country. The native breeds ranged from small-sized milking type breeds with low net gain, carcass weights and EUROP classification to larger multipurpose breeds with high net gains, carcass weights and EUROP classification. All Finnish and most of the Norwegian and Swedish native breeds had lower net gain and carcass weight than the dairy breeds in the same category and country, but with similar carcass conformation and fatness scores. The two Danish native breeds had higher net gain, carcass weight and conformation class than the reference dairy breed, but lower than the reference beef breeds. The net gain and carcass traits of the Icelandic native breed were similar to the smallest-sized native breeds from the other countries. The carcass traits of the native breeds indicate that they have comparative advantages in an extensive production system based on forage and marginal grasslands. They may also succeed better in the value-added markets than in mainstream beef production.

The international legal system of access and benefit-sharing of genetic resources (or ABS) under the Convention on Biological Diversity (CBD) is an ever-evolving field as its material, temporal and activity scope is still under discussion to meet the needs of the advancement of research and development activities as well as the questions of fairness and equity that evolve with them. Activities, such as research and development with digital sequence information (DSI), currently take considerable space in the negotiations and the lack of consensus between the Global North and Global South continues. This paper gets its raison d'être from this lack of consensus and aims to provide a better understanding of the debate around the fair and equitable sharing of benefits arising from genetic resources as well as states' sovereignty over their natural resources. As such, the paper provides an analysis of all relevant documents at the international level, starting from the UN Charter to the CBD final text with the hope of reminding the ongoing CBD negotiations why we have ABS in the first place and what the international community historically aimed for when regulating genetic resources at the international level. Looking back at why we had the first legally binding ABS instrument in the first place, and why we thought this instrument would achieve fairness and equity in dealing with genetic resources, will serve the interests of all Parties to the CBD and will hopefully enable them to interpret the provisions based on their overarching aim and reasoning.
