Оценка продуктивных и адаптационных способностей озимой пшеницы сорта меляг в различных агроклиматических зонах Молдовы

Abstract

The article presents the results of a study of the winter soft wheat variety Meleag, zoned in Moldova, according to the parameters of adaptability and productivity in various agroclimatic zones of the country - southern and northern. The predecessor of winter wheat was grain peas. The productivity of the Meleag variety varied greatly depending on the conditions of the year and the agroclimatic zone. In the northern zone, grain yield varied from 5.51 t/ha (2021) to 8.58 t/ha (2018), being the zone average of 7.10 t/ha. Under the conditions of the southern zone, the productivity of the Meleag variety varied from 3.88 t/ha (2022) to 6.15 t/ha (2021), being an average for the zone of 5.40 t/ha. The variability of the productivity of the Meleag variety in the northern zone was average (v=11.8%), and in the southern zone low (v=4.4%). The Meleag variety showed higher stress resistance in the southern zone - 2.77, in the northern zone it was 3.07. The index of genetic flexibility of the variety in the southern zone was 5.27 and higher in the northern zone - 7.05, which indicates a high degree of correspondence between the geneticist and environmental factors.
