Study regarding the variability of the pods productivity of a Phaseolus vulgaris var. nanus landraces.

Abstract Utilization of local genetic resources can lead to improvement of genetic progress in plant breading programs. There are many untested bean landraces with high potential for plant breading. Our study was performed on 56 bush bean landraces (Phaseolus vulgaris var. nanus) collected from Western and South-Western Romania, which were compared with some cultivars cultivated in that region. Two main characters were studied: the number and weight of seeds per pod. It was concluded that inside the collection there is a high variability for the two characters, which are dependent to the interaction with the environment. The specific condition from the experimental periods influenced significantly the average values for the two characters. There were local landraces with seeds larger than those of commercial varieties. Regarding the number of seeds in a pod, we could not discover useful cultivars. Exploitation of variability in populations can lead to detection of specimens, superior for their characters.
