Abstract The bean fly (Ophiomyia spp) is one of several yield limiting insect pests of common bean (Phaseolus vulgaris L.) in eastern and southern Africa. High performing common bean cultivars with the bean fly resistance, good agronomic traits and market-preferred attributes are yet to be developed in the region. The objective of this study was to evaluate the bean fly resistance and agronomic performance of common bean accessions adapted to the eastern and southern African regions and to select parental lines for breeding. Ninety-nine common bean accessions were evaluated in bean fly hotspot areas in two locations in Malawi during the 2018 and 2019 growing seasons. Damage severity (BDS), plant mortality rate (PMR) and pupa count (PC) were measured to evaluate resistance to the bean fly. The following agro-morphological traits were assessed: the length between first internode and fifth internode at first flowering (FIL), number of nodes at the first flower (NFF), stem diameter (SD) at 50% flowering stage, days to 50% flowering (DTF), days to 90% physiological maturity (DTM), number of pods per plant (NPP), number of seed per pod (NSP) and grain yield in kg ha−1 (GYD). The analysis of variance revealed significant genotypic variation (p

在选定的普通豆 (Phaseolus vulgaris L.) 种质中选择豆蝇 (Ophiomyia spp) 抗性和农艺性能

摘要 豆蝇（Ophiomyia spp）是非洲东部和南部常见豆类（Phaseolus vulgaris L.）的几种减产害虫之一。该地区尚未开发具有抗豆蝇、良好农艺性状和市场偏好属性的高性能普通豆品种。本研究的目的是评估适应东部和南部非洲地区的常见豆类种质的豆蝇抗性和农艺性能，并选择亲本系进行育种。在 2018 年和 2019 年生长季节期间，在马拉维两个地点的豆蝇热点地区评估了 99 种常见的豆类种质。测量损害严重程度 (BDS)、植物死亡率 (PMR) 和蛹数 (PC) 以评估对豆蝇的抗性。评估了以下农业形态特征：第一次开花时第一个节间和第五个节间之间的长度 (FIL)，第一朵花的节数 (NFF)，50% 开花期的茎直径 (SD)，50% 开花的天数 (DTF)，天数到 90%生理成熟度 (DTM)、每株豆荚数 (NPP)、每豆荚种子数 (NSP) 和以 kg ha−1 为单位的谷物产量 (GYD)。方差分析揭示了显着的基因型变异（p
