Prospects of phaseolin application as a molecular marker in common beans (Phaseolus vulgaris L.) breeding

Abstract

During the study, the phaseolin types in 24 bean varieties from the Novosibirsk SAU collection were determined: 20 varieties are of T-type, 2 varieties - S-type. Two varieties showed a type of phaseolin previously undetermined by polymerase chain reaction (PCR) method. It was conditionally designated as N-type by us. Statistical analysis of the relationship of phaseolin type with economic and valuable traits showed a reliable relationship with the mass of 1000 seeds and the number of seeds from the plant. A number of other traits showed evidence of differences uncertainty between phaseolin types. Further research with a large number of varieties is therefore required. In the early stages of the breeding process, however, the phaseolin type can be used in the selection of forms with valuable breeding traits.
