Studies on variability, correlation and path coefficient of Asalio (Lepidium sativum L.)

Abstract

Variability present among the eight asalio lines was studied. Phenotypic correlations and their direct and indirect effects were estimated for eleven traits using path analysis. Variability among the morphological, yield and quality traits were assessed. Seed yield per ha, number of siliqua per plant and test seed weight traits showed good variability among the traits. The line MLS-1007 was found as superior line with respect to seed yield. A positive coefficient of phenotypic correlation was found between plant height, days to 50% flowering, days to maturity, number of branches per plant, test seed weight, length of siliqua, oil percentage and oil yield per hectare with seed yield per hectare. However, path analysis revealed that days to 50% flowering, number of branches per plant, test seed weight, length of siliqua, number of siliqua per plant and oil yield per ha exhibited significance at high level in positive direction.
