引进品种的生育期和其原产地分布之间有着密切的关系:分布在与新疆同纬度地区的品种生育期较为适中;自新疆职北地区引进的品种过于晚熟;自新疆以南地区引进的品种较早熟。抗寒能力在引入新疆以后并没有太大的改变,而抗锈特性则有明显的变异。引进品种在条件更好时具有较大的丰产能力;在条件不頁的情况下较地方品种的适应性弱。 There is a close relationship between the growth period of introduced varieties and the distribution of their origin. The distribution of varieties in the same latitude with Xinjiang is more moderate; the varieties introduced from the northern part of Xinjiang are too late to be ripe; the varieties introduced from the south of Xinjiang Premature. The ability of cold resistance did not change much after the introduction of Xinjiang, while the anti-rust properties showed obvious variation. The introduction of varieties in the better conditions have a greater yield capacity; in the case of non-conditions less adaptability than the local varieties.
