Використання непрямих ознак та індексів у селекції квасолі звичайної на стабільну продуктивність

Abstract

The article presents the results of the studies of the productivity and 11 in- dex characteristics of garden bean collection of different ecological-geographical origin under the conditions of forest-steppe of Ukraine. 11 sources of the complex of economically valuable characteristics and 5 stable productivity sources are defined and recommended for practical selection. The productivity pleiads (productivity, HI, Mx, AI, I, ГІ with the HI detector-characteristics) and harvest index (HI, productivity, Mic, AI, SI) are defined in the groups of determinantal and indeterminantal varieties at the level of intervarietal phenotypic correlations r≥ 0,5. HI and ГІ are recommended to use for the increase of estimation reliability of the breeding lines at the early breeding stages as the secondary characteristics
