Abstract
SUMMARY: Yield stability in beans from diverse sources in Malawi was estimated using the statistical parameters of genotype X environment variance, slope and standard error from regression. The heterozygous F2 and the most complex synthetic mixture were very stable, although not significantly different from some pure genotypes. The mean yields of most mixtures were marginally higher than the average of their components. There was a linear relationship between magnitude of diversity and stability. Evidence for heterozygote advantage was demonstrated.This publication has 11 references indexed in Scilit:
