TOMLEKOVA, N., L. KRASTEVA, I. PORYAZOV and P. IVANOV, 2000. Conformity of electrophoretic families of Phaseolus vulgaris L. collection samples in Bulgaria with morphological and economic indexes. II. Plant growth habit, presence of fiber in pods. Bulg. J. Agric. Sci., 6: 17-20
Domestic germplasm, selection lines and cultivars of common beans P. vulgaris species were studied. It was established that there is a correlation in the distribution of Bulgarian genotypes of the Andean and meso-American gene pools according to their phaseolin types that account for their allocation in these two groups, on the one hand and the morphological indexes such as plant growth habit and presence of fiber in the pods, on the other.
The representatives of the Andean gene pool in the Bulgarian collection are related predominantly to determinate growth habit and absence of fiber in the pods. The genotypes of the meso-American germplasm have a prevailingly indeterminate growth habit and presence of fiber. The "Ca" phaseolin type is fully related to determinate growth habit and absence of fiber in the pods. The objective of this study is to establish the relationship between the phaseolin type and the morphological indexes such as plant growth habit and presence of fiber in the pods.
Key words: Phaseolus vulgaris L., gene pools, phaseolin types, plant growth habit, presence of fiber in the pods
