研究亲本对丝黑穗病的抗病性及抗病性遗传,对指导抗丝黑穗病育种有重要意义。为此,1981～1983年研究了一些丝黑穗病抗源的抗病性遗传,现介绍如下。一、材料和方法研究材料选用 Tx622A、Tx623A、Tx624A、麦卡 A4个免疫不育系,营4A1个高抗不育系,3197A1个感病不育系,晋粱五/恢7、多穗高粱两个免疫恢复系,298/4003、怀来/4003、怀来/渤粱一、三尺三/白平、铁恢6、白平、4003、锦恢75、忻粱52、三尺三、0—30、523、654、627、307、5—26、121、晋辐1等18个感病恢复系,组配的杂交组合42个。每年将上述亲本及其杂交种按顺序排列种
Studying the parents’ resistance to head smut and the inheritance of disease resistance are of great significance to guide the breeding of resistant head smut. To this end, from 1981 to 1983 studied a number of resistance to head smut disease resistance genetic, are presented below. Materials and Methods The research materials used were Tx622A, Tx623A, Tx624A, McCardina A4 immune CMS, Camp 4A1 high resistance CMS, 3197A1 susceptible CMS, Jinliwu / Hui 7, multi-spike sorghum Two immune recovery lines, 298/4003, Huailai / 4003, Huailai / Bo Liang, three feet three / white flat, Tiehui 6, white flat, 4003, Jin Hui 75, Xin Liang 52, three feet three, 0-30,523,654,627,307,5-26,121, Jinfu 1 and other 18 susceptible restorer lines, with a combination of 42 combinations. The above-mentioned parents and their hybrids are arranged in order each year
