摘 要:青藏高原平均气温低,昼夜温差大,降雨量少,光照充足。在春小麦品种的选育中,无论在形态性状和生态特性方面,还是在抗逆性方面,育种的选择指标,与平原及沿海地区相比,都有较大的不同。本文总结了作者35年来在青海从事作物育种和引种的经验及他人的智慧,制定了选育适应高原地区丰产优质小麦品种的常规目标。在穗、叶、茎、根及生育期特性的选择方面,提出与内地小麦育种不同的选育指标。为适应高原地区的特点,提出了个体增产潜力的选择优先于群体性状的原则。In Qinghai-Tibet highland Spring wheat variety development by selection and Index of breeding of spring wheat, both morphological character and ecological character and resistance should be different from inland and coastal area because of lower mean temperature, large temperature difference between day and night, lower rainfall and full sunshine. In order to suit to local production condition, this paper gives the normal objection of spring-wheat seed selection with high yield and high qrality, the selection index of spring-wheat character such ad growing season,ear,leaf, stem and so on,and the principle that the potential of individual yield is priority selection, to population characters.
