SOWING DATES AND ADAPTABILITY OF TYPICAL WINTER BARLEY AND FACULTATIVE VARIETIES

Winter barley production includes typical winter varieties and facultative (dual-purpose) varieties that can be sown both in autumn and spring. These groups differ in their genetic nature, and their type of development is determined by the presence of three pairs of genes in the genotype.冬大麦生产涵盖典型冬性品种与可于秋、春两季播种的兼性（两用）品种（facultative (dual-purpose) varieties）。两类品种的遗传特性存在差异，其发育类型由基因型（genotype）中的三对基因所决定。
