Abstract

Background: Pallar (Phaseolus lunatus) is a grain legume of great socioeconomic importance in Peru, which has been domesticated in the past by pre-Hispanic cultures. Objective: Carry out the agromorphological characterization of 36 accessions from the Pallar National Collection of the Germplasm Bank of the National Institute of Agrarian Innovation (Peru). Methodology: 16 qualitative characters and 10 quantitative characters were compared using descriptive analysis, ANOVA and Scott Knott test, correlation, principal components and hierarchical grouping. Results: There was a positive correlation between the length of the main stem and the average number of mature pods per plant, average number of seeds per plant, average weight of seeds per plant and average weight of seeds; Likewise, a negative correlation was found between the number of locules per mature pod and the length and average weight of the seeds. Implications: The agromorphological characterization of the pallar is necessary for the conservation of genetic resources originating in Peru. Conclusions: Phenotypic variability was found among the Pallar accessions; Thus, the existence of three groups was established among the accessions in relation to quantitative characters, highlighting the high values of average number of seeds per plant, seed thickness, number of locules per mature pod, length of the main stem and average number of seeds. mature pods per plant. The promising accession was 14ac with respect to the highest average number of mature pods, average number of seeds and average weight of seeds per plant.

秘鲁伊尼亚 PALLAR(Phaseolus lunatus L.)GERMOPLASMA 采集的植物学特征和植物多样性
背景:Pallar(Phaseolus lunatus)是秘鲁一种具有重要社会经济意义的谷物豆类,过去曾被前西班牙文化驯化。研究目的对秘鲁国家农业创新研究所种质库的 Pallar 国家保藏品中的 36 个品种进行农业形态学鉴定。方法:使用描述性分析、方差分析和斯科特-诺特检验、相关性、主成分和层次分组法对 16 个定性特征和 10 个定量特征进行比较。结果主茎长度与每株成熟豆荚的平均数量、每株种子的平均数量、每株种子的平均重量和种子的平均重量之间存在正相关;同样,每株成熟豆荚的子房室数量与种子的长度和平均重量之间存在负相关。影响:为了保护原产于秘鲁的遗传资源,有必要对 pallar 进行农业形态学特征描述。结论因此,在定量特征方面,发现了三个群体,即每株平均种子数、种子厚度、每个成熟豆荚的子房数、主茎长度和每株成熟豆荚的平均种子数。有希望的品种是 14ac,其平均成熟豆荚数、平均种子数和平均单株种子重量最高。

期刊介绍: The journal is an international peer-reviewed publication devoted to disseminate original information contributing to the understanding and development of agroecosystems in tropical and subtropical areas. The Journal recognizes the multidisciplinary nature of its scope and encourages the submission of original manuscripts from all of the disciplines involved in this area. Original contributions are welcomed in relation to the study of particular components of the agroecosystems (i.e. plant, animal, soil) as well as the resulting interactions and their relationship/impact on society and environment. The journal does not received manuscripts based solely on economic acpects o food technology.
