近几年来,禾谷类作物的属间杂交工作有很大进展。这里主要阐述有关黑麦分别与各种大、小麦杂种杂交产生三属杂种的情况以及各品种在杂交亲和性上所表现的差异。试验根据杂交中胚乳容易败育的现象,在授粉后24小时和48小时,用注射器将75ppm的GA_3注射到每朵花内。大—小麦杂种授以Prolific黑麦的花粉后,Emir×中国春组合得到了4.0％最高结 In recent years, great progress has been made in the intergeneric hybridization of cereal crops. Here mainly elaborated on the rye, respectively, with a variety of large, wheat hybrids produce three genus hybrids and hybrid varieties of the performance of the differences. The test was based on the phenomenon of easy abortion of the endosperm in the cross and, at 24 hours and 48 hours after pollination, 75 ppm of GA_3 was injected into each flower with a syringe. Large-wheat hybrids pollinated with Prolific rye gave the Emir × Chinese Spring combination a 4.0% maximum knot
