Correlation and path analysis in F2, F3 and biparent crosses of mustard
Keywords: Mustard, Correlation co-efficient, Path co-efficient analysis
AbstractThe genetic study of F2 crosses in mustard was undertaken with a view to identify the potential F2 crosses for their use in individual plants selection. Three F2 crosses were C-I (Varuna X RH-819), C-II (Ashirwad X RH-819) and C-III (ACN-9 X Geeta) raised during rabi 2012-13 and data were recorded on six characters i.e. days to first flower, days to maturity, plant height, number of primary branches per plant, number of siliqua per plant and seed yield per plant. The correlation studies at genotypic level revealed positive significant association of seed yield per plant with number of siliqua per plant and with number of primary branches per plant in all the crosses studied and with plant height in some cases. The study on path analysis indicated the significance of number of siliqua per plant and number of primary branches per plant as the promising characters to increase seed yield per plant either directly or indirectly.
