摘要
考察结果表明 ,主要推广品种本身均具有广泛的基因容量和遗传背景 ,如亲本选配妥当 ,能在一定时期内抵抗不同的不良生存环境且能在较广的生态区域内种植 ,具有较好的适应性。但主导品种仍属于近亲种植 ,遗传基础相当狭窄 。
The pedigree analysis of Henan wheat extension varieties showes that some of them have rich gene content and diversity genetic background. If their parents are matched properly, the varieties derived from them would have a good genetic adaptation to stress environments. The main tested varieties, however, have a narrow genetic basis. More attention should be payed to the germplasm and breeding materials in wheat breeding work.
