CORRELATION DEPENDENCES BETWEEN TWENTY-ONE TRAITS OF SOME BULGARIAN COMMON BEAN GENOTYPES

The main aim of this investigation was to estimate the interrelationships between common bean quantitative traits using correlation coefficients, as well to select the most perspective of the investigated genotypes, which possess the best traits interesting for further breeding works.
Three-year investigations (2003–2006) were conducted into thirty-one Bulgarian common bean genotypes.
Twenty-one important seed, pod and plant traits were evaluated.
Strong positive correlations were determined between the following traits: weight of pods with seeds and length of pods; number of pods with weight of seeds per plant; weight of seeds per plant with weight of over grounded plant part and number of first pod-bearing nodes; number of pods per plant with number of pod-bearing nodes; weight of over grounded plant part with number of pod-bearing nodes, thickness of hypocotyls and number of pods per plant.
Negative correlations were found between the following traits: height of the set on lowest pod with number of pods (under 10 cm), weight of seeds per plant, number of branches, pod-bearing nodes, pods per plant and seeds per pod.
Breeders can use all these correlations for further work in breeding programs.
