Genetics of Heat Tolerance during Reproductive Development in Common Bean
Common bean (Phaseolus vulgaris L.) is grown in regions where high temperatures during reproductive development reduce yields. The purpose of this study was to identify sensitive growth stages during reproductive development and to investigate the genetics of heat tolerance during these stages. Exposure to high temperatures during two reproductive growth stages, namely flower bud formation and ...
متن کاملApplication of Stress Indices for Heat Tolerance Screening of Common Bean
Common bean is adapted to relatively cool climatic conditions and temperatures of>30 Cduring the day or>20 C at night result in yield reduction. The long-term goal of breeding for heat tolerance is the development of germplasm with improved field level tolerance under variable temperature conditions. Using previously developed stress indices, this studypresents results fromhigh temperature scre...
متن کاملMorpho-Physiological Characterization Related to Drought Tolerance of Common Bean (Phaseolus Vulgaris L.) Genotypes
Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...

متن کاملTepary Bean: A Short Duration Summer Crop in Virginia*
INTRODUCTION Wheat farmers in Virginia and southeastern US could benefit greatly from the availability of a shortduration summer crop that could be produced during the period between wheat harvest in middle of June and before planting of the next wheat crop during October. Some wheat farmers plant soybean as a double crop system, but the productivity of double-cropped soybean is extremely low a...
