INFLUENCE OF SEGREGATING GENERATIONS ON CHARACTER ASSOCIATION IN SESAME

Published on

Analysis of character association in the F3 and F4 generations of three sesame crosses
revealed differences in mean and variance for maturity duration, primary branches,
productive capsules and seed yield. The association between seed yield and number of
capsules was highly positive and consistent over generations in all the crosses. Similarly,
the positive association of primary branches with seed yield, number of capsules and days
to maturity was also consistent over generations in all the three crosses. The association of
seed yield with oil content which was generally nonsignificant indicated that selection
cannot be practiced for oil improvementin segregatinggenerations. Further, character pairs
showing medium to moderate associations showed high degree of fluctuation in the
correlation coefficients.
