八倍体小偃麦与普通小麦杂交选育抗旱小麦品种的研究

A STUDY ON THE DEVELOPMENT WITH DROUGHT RESISTANCE OF WHEAT VARIETY THROUGH CROSSES BETWEEN OCTOPLOID TRITIELYTRIGIA TYPES AND TRITICUM AESTIVUM

利用八倍体小偃麦与普通小麦杂交，通过连续选择选育出抗旱小麦品种小偃５９７。试验结果表明，小偃５９７抗旱，叶组织细胞膜的稳定性（７．６％），叶片持水力（５１．６０％）和叶组织相对含水量（７７．０６％）高。株高８５ｃｍ，白粒，角质，品质优。每公顷６７５０ｋｇ。

With crossing between octoploid Tritielytrigia types and Triticum aestivum ,the drought resistant wheat variety Xiaoyan 597 was bred by continuous selection.The results tested show that Xiaoyan 597 is resistant to drought.Stabilty of the cell membrane in the leaves (7.6%),water holding capacity of the leaves (51.6%) and relative water content (77.06%) are higher.Plant height is 85 cm.The kernels are hard,white and good quality.Grain yield is 6750 kg/hm 2.
