Abstract
The present investigation entitled, âAssessment of Genetic Variability in F1 hybrids of Indian Mustard (Brassica juncea L.) for Yield and its Contributing Traitsâ was conducted at Crop Research Centre, SVPUAT, Meerut, Uttar Pradesh during 2024-25 crop season. The study aimed to evaluatethe extent of genetic variation present among the hybrids and the parents of Indian mustard for yield and its contributing traits. The experiment followed a complete randomized block design (CRBD) with three replications. The phenotypic coefficient of variation was greater than genotypic coefficient of variation suggesting environmental influence. High heritability coupled with high genetic advance as percent of mean was recorded for traits such as seed yield per plant followed by biological yield and test weight indicating the predominance of additive gene action. The results underlined the potential of exploiting genetic variability for improving yield and accelerating genetic gains in mustard breeding programs.
