Evaluation of the yield and some indicators of adaptivity of beans varieties (Phaseolus vulgaris).

Abstract

The article presents the results of environmental testing of five varieties of beans, bred in Research Institute of Field Crops “Selectia" in different agro-climatic zones of Moldova (North, Central, and South) within the State Commission on Crop Varieties Testing trials network. The maximum grain yield of beans was produced in North zone - 2.79 t/ha, 0.38 and 1.65 t/ha higher than medium variety productivity in Central and Southern areas, respectively. The varieties of beans taken in study showed a high degree of potential productivity realization 72,1 - 81,6%. The highest grain yield an average by zones was obtained from varieties Garofitsa - 2.30 t/ha. The studied varieties of beans showed a high percentage of realization of potential productivity 72,1-81,6%. The varieties of beans with the regression coefficient on the environmental conditions above 1 refers to the highly plastic - Garofitsa with bi = 1,30 and Aluna with bi = 1,06.
