辽宁省冬麦北移种植中品种筛选问题的探讨

The Exploration of Cultivar Screening for Growing Winter Wheat in Northem Region of Liaoning proving

自１９９１年在辽宁省引种试种冬小麦。经过６年的试验研究，认为品种筛选是冬麦北移种植初期的一项核心内容。对品种的要求应该是抗寒、耐旱、早熟及高产。品种来源应该是南种北引与北种南引相结合以及对引进品种的改良。筛选方法是通过多年多点试种鉴定，在高胁迫环境下，对引进品种的抗寒性进行再选择。

Summary introduction of some winter wheat cultivars since 1991,these have been experimented for 6 years It could conclude that during initial growing winter wheat in northern region the key contents are cultivar screening The requriments of cultivar should be freeze resistant,drough resistant,early maturing and high-yield The source of cultivars should be introdution of cultivars from norther region combining with from southern region,and improvement of these cultivars The screening method is identification and test growing of these cultivars in many plots over many years,under high stress environment reselection for freeze resistance
