گزینش صفات مطلوب برای بهبود عملکرد ارقام ماش تحت شرایط خشکی

In order to study the relationships between traits affecting grain yield in six Mungbean cultivars two seprate random complete block designs were conducted in three replicates under normal and drought. Conditions Correlation analysis showed that phenological traits had the most positive and significant correlation with seed yield. Stepwise regression performed two traits namely, days to pod and days to 50 percent flowering, respectively and models was totally identified  99.9  percent of yield changes. Path analysis for yield of plant traits showed that days to pod emergence had direct and negative effects on yield was also the trait days to flowering and -50 percent flowering had the highest direct positive effects on yield. Therefore, this trait can be good for using in breeding programs to increase yield performance of mungbean cultivars.
