Cowpea fresh pods are consumed as green vegetables in many countries in Southern Europe. Among cowpea cultivated material, a relatively large number of landraces can be found, maintaining species genetic diversity. To assess the value of these landraces in breeding programs, the characterization and estimation of diversity levels is therefore required. In the present study, an estimation of the diversity and evaluation of cowpea landraces originating from Portugal, Spain and Greece, in terms of their fresh pod traits, was performed, aiming to assist with the problem of low cowpea production in Southern Europe.
A notable mean total phenotypic diversity (H = 0.57) was observed in the whole collection. The Spanish cv. - gr. unguiculata collection exhibited the highest value of total phenotypic diversity (0.56). Landraces did not differ significantly from each other regarding the three countries of origin. Landraces such as Cp4906, Vg60 and BGE038478 presenting higher values of some traits studied could contribute to the breeding of new cowpea varieties for fresh pod production. Positive correlations were observed, indicating the feasibility of breeding for preferable traits regarding fresh pod consumption.
The present study has revealed a wide diversity among and within cowpea landraces that could enhance fresh pod production in South European countries. © 2017 Society of Chemical Industry.
在南欧的许多国家，豇豆鲜荚被作为绿色蔬菜食用。在豇豆栽培材料中，可以发现数量相对较多的地方品种，它们保持着物种的遗传多样性。因此，为了评估这些地方品种在育种计划中的价值，需要对其进行特征描述和多样性水平估计。在本研究中，对源自葡萄牙、西班牙和希腊的豇豆地方品种的鲜荚性状进行了多样性估计和评价，旨在解决南欧豇豆产量低的问题。
在整个收集样本中观察到显著的平均总表型多样性（H = 0.57）。西班牙的cv. - gr. unguiculata收集样本表现出最高的总表型多样性值（0.56）。就原产国这三个国家而言，地方品种之间没有显著差异。一些所研究性状值较高的地方品种，如Cp4906、Vg60和BGE038478，可有助于培育用于鲜荚生产的新豇豆品种。观察到了正相关关系，表明针对鲜荚消费的优良性状进行育种是可行的。
本研究揭示了豇豆地方品种之间以及品种内部存在广泛的多样性，这可以提高南欧国家的鲜荚产量。© 2017化学工业协会。
