Abstract

Evaluation of winter wheat cultivars has been carried out in relation to their crop capacity, ecological stability, and plasticity under conditions of the light grey forest soils of the Nizhny Novgorod oblast. In 2012–2016, the crop capacity of the cultivars included into the study was 53.0 centner/hectare on average (V = 23.3%) varying from 16.3 to 89.2 centner/ha; the year-to-year and cultivar-to-cultivar difference reached 51.7 and 12.4 centner/ha, respectively. The crop productivity was influenced mainly by weather conditions (73%), whereas the cultivar contribution made only 9%. The maximum stability and plasticity were observed for the soft winter wheat cv. Nemchinovskaya 57 bred by the Nemchinovka Federal Research Center. The cultivar demonstrated a low variation coefficient (33%) and the highest homeostaticity (1.59) and stress resistance (47.4). This cultivar was also determined as the most adaptive one under conditions of the Nizhny Novgorod region.

下诺夫哥罗德州条件下冬小麦品种的产量，生态稳定性和可塑性的评估

摘要

在下诺夫哥罗德州的浅灰色森林土壤条件下，已针对冬小麦品种的作物产量，生态稳定性和可塑性进行了评估。在2012–2016年，纳入研究的栽培品种的平均产量为53.0厘米/公顷（V = 23.3％）从16.3至89.2分/公顷 年与品种间的差异分别达到51.7和12.4仙/公顷。作物生产力主要受天气条件影响（73％），而品种贡献仅占9％。观察到软冬小麦的最大稳定性和可塑性。Nemchinovskaya 57由Nemchinovka联邦研究中心培育。该品种表现出低变异系数（33％）和最高稳态（1.59）和抗逆性（47.4）。在下诺夫哥罗德地区的条件下，该品种也被确定为适应性最强的品种。
