摘要
对4种杂交模式82个杂交组合的7927株杂种苗抗寒力进行了调查,统计结果表明:在简易覆盖越冬条件下,(AA×BB)×AA*的抗寒力最强,正常萌芽植株占杂种苗总数的93.0%;(AA×BB)×(AA×BB)次之,占87.5%;AA×BB居第三位,占67.2%;(AA×BB)×BB后代抗寒力最弱,仅占43.8%。
The cold resistance oi 7927 cross seedlings whinh.came from 82 cross combinations of 4 cross models was investgated. The calculaled result showed that:in the condition of simple and easy cover through the wiater the cold resistance of(AABB)×AA was the strongest,the normal,spreat plant made up 93.0 percent of the tolalcross seedlings; the second was (AA×BB)×(AA×BB),making Up 87.5 percent; the third was AA×BB, making up 67.2 percent;the wasg wax(AA×BB)×BB,making up only 48.3 percent.
