普通小麦与硬粒小麦正反杂交差异研究
A Difference Study on Reciprocal Crosses of Common Wheat with Durum Wheat
摘要
Abstract
Durum w heat contains some useful traits such as multi-floret ,etc .In order to evaluate the degree of difficulty for transferring such excellent trait to common wheat ,the reciprocal cro-sses were made between one durum wheat and three common wheat genotypes .The seed setting rate of hybridization and the germination rate and setting rate of hybrids were studied .The result showed that the seed setting rate of hybridization was higher when durum wheat was used as fe-male parent (51 .19% in average) .The seed germination rate of hybrids was higher when durum wheat was used as male parent (86 .67% ) ,while the germination rate of the cross Shijiazhuang 11 × Zhoumai 22 was zero .In addition to the cytoplasm difference between common wheat and du-rum w heat ,the genotype diversity of common w heat played an important role in the germination rate of hybrids .关键词
