The purpose of the research was to substantiate the assortment of Aсtinidia deliciosa cultures for cultivation in Russian humid subtropics according to the criteria for the adaptability of varieties using parameters of productivity, ecological stability and economic efficiency. Productivity parameters (potential, absolutely stable, long-term average) were established using multiple regressions model of the influence of weather factors on harvest variety in system “weatherharvest”. Ecological stability was determined for 14 years by the coefficient of crop variability, ecological plasticity, periodicity and fruiting stability. Cost-performance of varieties was evaluated by profitability of each variety on the base of the long-term productivity and quality of fruit by mass. In humid subtropics conditions the cultivation of late varieties (Hаyward K-10, Hаyward K-12, Hаyward K-17 and Kivaldi) is most appropriate. |
