Rajmah, Germplasm, Variability, Heritability, Genetic Advance, Path AnalysisAbstract
In the present study, the genetic diversity and the association among seventeen morphological and yield traits were assessed among 14 Rajmah (Phaseolus vulgaris L.) landraces collected from different places in the Barak Valley of Assam. The results revealed high estimates of the genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) for plant height, number of seeds per plant, and seed weight. Moderate estimates of GCV and PCV for number of pods per plant, seed weight per pod, average pod weight, seed breadth, 100-seed weight and seed yield. The analyses revealed that selection would be highly effective for the characters like plant height, number of seeds per plant and seed weight per plant, number of pods per plant, seed weight per pod, average pod weight, seed breadth, 100-seed weight, and seed yield as these traits showed high to moderate estimates of GCV and PCV along with high estimates of heritability coupled with moderate to high estimates of genetic advance as per cent of means. Correlation and path analysis revealed that besides seed yield, number of branches per plant, leaf length, leaf breadth, pod length, number of seeds per plant, seed yield per plant, number of pods per plant, number of seeds per pod, seed breadth, 100- seed weight, seed length, and days to 50% flowering are some of the important yield attributing traits in Rajmah.
