Genetic correlation between various traits in F2 populations derived from crosses involving specialty varieties of rabi sorghum

The genetic nature of character association for various traits was studied in Rabi sorghum using F2 populations derived from four crosses of M 35-1 with specialty varieties viz., AKJ-1 (flaking), KMJ - 1 (popping), and SMJ-1 & RSJ-1 (hurda purpose). These varieties derived from landraces are recommended for cultivation in Northern Dry Zone of Karnataka. Grain yield per plant and fodder yield per plant were significantly and positively correlated with all the yield components studied plant height, panicle length, panicle breadth, panicle weight and 100 seed weight in the crosses M 35-1 x AKJ-1 and M 35-1 x KMJ-1. Positive and significant association was observed among these yield components in these crosses. |
