渭北旱地小麦育种,应在稳产基础上求高产。以稳产250kg/亩以上的优质、早熟品种为主攻方向。育种实践证明,在典型条件的地方,能育成类似条件所需性状的理想品种,应逐步把洛川建成旱地小麦育种中心。亲本选配宜选用链式、梯式为好。轮回杂交用于多目标大群体选种也非常方便。今后应在提高单穗生产力和抗倒伏性方面下功夫。
Weibei dryland wheat breeding, should be on the basis of stable production and high yield. To stable yield 250kg / mu above the quality, precocious varieties as the main direction. Breeding practices have proved that in typical conditions, the ideal variety that can cultivate the traits required by similar conditions should gradually be built into a dryland wheat breeding center in Luochuan. Parents should use the optional matching chain, ladder as well. Reincarnation hybrids for multi-target large group selection is also very convenient. In the future, efforts should be made to improve the productivity and lodging resistance of a single spike.
