本研究采用单花针注法接种,以病小穗数为统计单位,对1个感病品种和6个抗病品种杂交取得的F_1、F_2、B_1、B_2及其P_1和P_2进行了抗性调查,研究了这6个小麦品种抗赤霉病性的遗传,结果表明:6个抗性亲本抗性由强到弱的顺序为繁60096、苏麦3号、宁7840、翻山小麦、龙79B-1165、克80F_(3-119),抗病性以加性效应为主,显性效应不可忽视,互作效应不重要,抗病性呈部分显性,抗感病亲本之间存在3—4对基因之差异。
In this study, single flower needles were used for inoculation, and the number of spikelets was used as a statistical unit to test the resistance of F_1, F_2, B_1, B_2 and P_1 and P_2 obtained from one susceptible and 6 resistant cultivars Investigation and study on the inheritance of the resistance of these six wheat cultivars to FHB showed that the order of the resistance of the six resistant parents was 60096, the intensity of the resistant parents was 40096, that of Sumai 3, Ning 7840, 79B-1165 and 80F_ (3-119). The disease resistance was mainly additive effect, the dominant effect was not negligible, the interaction effect was not significant, disease resistance was partially dominant, and there was 3 -4 pairs of genes differences.
