ABSTRACT
In the F2 generation of the cross between burley varieties,Ky 14 andKy Ex 42, estimates of additive genetic variance were significant for yield, days to flower, and number of leaves. All estimates of dominance variance, additive X additive variance, and interactions between genetic variances and years were smaller than twice their standard errors. The gain expected from selecting and recombining the best 10% of theF 2 plants ranged from 4% for number of leaves to 8.6% for yield. Additive genetic correlations between pairs of agronomic characters were positive. Yield and number of leaves were negatively correlated with total alkaloids.
