tailieunhanh - Genetic variability and trait association studies in Indian mustard (Brassica juncea L. Czern & Coss)

The basic requirement for crop improvement program is existence of genetic variability for selection of superior genotypes. For efficient indirect selection of complex characters it is important to know the association between traits. With the aim to study the genetic variability and correlation between traits among thirty Indian mustard genotypes, these genotypes were evaluated in Randomized Block Design during Rabi 2016-2017. Study revealed that number of secondary branches, seed yield per plant and seed yield per plot exhibited high to moderate GCV accompanied with high to moderate PCV indicating that selection may be effective based on these traits. High to moderate heritability with high to moderate genetic advance was found for number of secondary branches and number of siliqua per plant. Correlation studies indicated seed yield per plot showed positive and significant correlation with days to 50% flowering, days to maturity, number of siliqua per plant, length of siliqua and number of seeds per siliqua. The path coefficient analysis revealed that seed yield per plot, days to 50% flowering and plant height has positive direct effect on seed yield per plant which suggests that direct selection for these traits can be done for improvement of yield. | Genetic variability and trait association studies in Indian mustard (Brassica juncea L.
