分析了黑龙江省东部地区的自然地理状况,及以往小麦高产育种依靠多穗夺高产存在的弊端和依靠大粒夺高产的不稳定性,进而提出了以“根据东部地区的地理特性,稳定穗数,争取大穗、多粒高粒重,提高单穗重”为主要选择目标的选育策略,为高产小麦育种特供参考。 Based on the analysis of the natural geography in the eastern part of Heilongjiang Province and the malpractice of the high yield of wheat relying on the multiple spike yield and the instability of relying on the large yield of the high yielding wheat breeding in the eastern region of Heilongjiang Province, , Strive for the big spike, high grain weight and improve the single spike weight "as the main selection target breeding strategy for high yield wheat breeding for reference.
