摘 要 ：本工作以改进八倍体小黑麦与六倍体小黑麦的经济性状为目的,对60个杂交组合 F_1的田间出苗率、结实率、杂种后代的性状分离、新类型的形成以及细胞遗传的若干问题进行了探讨,观察到 F_1田间出苗率、结实率以八倍体为母本的杂交组合显著好于以六倍体为母本的杂交组合。由于杂种是普通小麦、硬粒小麦、黑麦三个物种种质的再度组

Abstract:In order to improve some economic characters of octoploid and hexaploid triticales,60 combinations of cross between octoploid triticale andhexaploid triticales were made.When the octoploid triticales were usedas female parent the germination rate of hybrid seeds is much betterthan that of their reci
