山葡萄抗寒力在种间杂交后代中的遗传

INHERITANCE OF Vitis amurensis Rupr.COLD RE I TANCE IN INTER PECIFIC HYBRID PROGENY

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.
