Comparing the yield of promising white bean lines in Shahrekord

In this study, 10 promising lines of white bean (Phaseolus vulgaris L.) along with Dorsa and Paak control cultivars were evaluated in a randomized complete blocks design with three replications over two years. During the growing season, the status of the lines was determined in terms of growth type, number of days from planting to flowering and maturity, number of pods per plant, number of seeds per pod, 100-seeds weight, single plant yield and total yield. Results of combined analysis of variance over two yearsfollowed by LSD test showed that grain yields of lines 7, 3 and 6 were 49%, 42% and 41% higher than the control, respectively. Of these three lines, line 3 was superior because of its higher 100-seedsweight. Therefore, this line is suitable for Shahrekord and similar areas. Correlation coefficients of grain yield and its main components were positive and significant. Further experiments to introduce Line 3 as a new cultivar will take place in the coming years.
