Abstract

A comparative assessment of 14 pearl millet genotypes transpired for growth and yield traits under arid conditions of Southeast Kazakhstan. In this study, the green and dry plant biomass and grain yield of 14 pearl millet genotypes’ assessment ensued under rainfed conditions in Southeast Kazakhstan. For green biomass yield, the three pearl millet genotypes Bair Bajsa, HHVBC tall, and J-6 performed better and were high yielders ranging from 39.07 to 39.94 t/ha. The accumulation of dry biomass (as hay) was different and varied widely from 3.17 to 17.36 t/ha; however, the maximum dry biomass appeared in the genotype HHVBC tall. Genotype HHVBC tall was leading for green and dry plant biomass formation and has the potential for grain yield under rainfed conditions of Southeast Kazakhstan. Drought always negatively impacted the production of fodder and grains; however, genotype HHVBC tall assures a stable plant biomass and seed production under arid conditions. In dry Southeast Kazakhstan, pearl millet, a drought-resistant crop, is a highly productive, valuable fodder and grain crop based on quality yields of biomass and grains. Subject to the cultivation technology and according to weather conditions, on average, the pearl millet genotypes form a green mass biomass yield of 40 t/ha and grain yield of 2.2 t/ha under rainfed conditions of Southeast Kazakhstan. For cultivation in the Republic, it is necessary to expand pearl millet as an annual crop, most adapted to extreme agroecological conditions.

哈萨克斯坦东南部干旱条件下珍珠粟基因型比较评价

对哈萨克斯坦东南部干旱条件下14个珍珠粟基因型的生长和产量性状进行了比较评价。本研究对哈萨克斯坦东南部雨养条件下14个珍珠粟基因型的绿、干植物生物量和籽粒产量进行了评价。在绿色生物量产量方面，3个珍珠粟基因型Bair Bajsa、HHVBC tall和J-6表现较好，产量在39.07 ~ 39.94 t/ha之间。干生物量(如干草)积累量不同，在3.17 ~ 17.36 t/ha之间变化较大;而干生物量最大的是HHVBC基因型tall。在哈萨克斯坦东南部旱作条件下，HHVBC tall基因型在绿色和干燥植物生物量形成方面领先，具有粮食产量潜力。干旱对饲料和谷物的生产产生不利影响;然而，HHVBC基因型高确保在干旱条件下稳定的植物生物量和种子产量。在干旱的哈萨克斯坦东南部，珍珠粟是一种抗旱作物，是一种高产、有价值的饲料和粮食作物，以生物质和谷物的优质产量为基础。受栽培技术和气候条件的影响，在哈萨克斯坦东南部旱作条件下，珍珠粟基因型的平均绿色生物量产量为40 t/ha，籽粒产量为2.2 t/ha。为了在共和国种植，有必要扩大珍珠粟作为一年生作物，最适应极端的农业生态条件。

期刊介绍： The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO). Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society. The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards. The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
