在5种密度下研究了小麦杂交种及亲本的产量性状表现。结果表明,小麦杂交种对密度的适应能力很强,群体产量都比较稳定。群体产量之所以稳定是因为单株穗数起了主要的调节作用,然后依次为每穗粒数和千粒重.低密度时杂种小麦的结实率更高,建议杂种小麦适当降低播种密度;杂种小麦的高产育种应在杂交种有分蘖潜力的基础土主攻粒大、粒多.
The yield traits of wheat hybrids and their parents were studied at five densities. The results showed that the ability of wheat hybrids to adapt to the density is very strong, the population yield is relatively stable. The reason why population yield is stable is that the number of spikes per panicle plays a major role in the regulation, followed by the number of grains per spike and grain weight per hectare. The seed setting rate of hybrid wheat is higher at low density, Breeding of high-yielding hybrids should have tillering potential of the main foundation of the main grain, grain and more.
