Synopsis

Synopsis

Seedling vigor and fall growth habit of the 91 diallel crosses among 14 alfalfa clones were scored in 3 and 4 states, respectively. Estimated, variance components for general (by far the largest component) and specific combining ability and the interaction of these with locations were all highly significant for both characters. Clones differed in their contributions to both additive and nonadditive genetic variances. The two characters were highly correlated (range +0.82 to 0.93), and interlocation correlations for each character were likewise high.
