根据田间成株期抗病性和3个水平抗性因素(病斑数量、病斑面积和单位病斑面积的产孢量)的鉴定结果,利用11个正常细胞质的玉米自交系,通过双列杂交研究分析病级及3个水平抗性因素的遗传规律。按Griffiug的方法2[P(P+1)/2]模式I分析配合力。结果表明,一般配合力方差和特殊配合力方差都达极显著水准(P=0.01),说明加性与非加性基因效
According to the identification of resistance to disease at the adult plant stage and three levels of resistance (number of spikes, lesion area and sporulation of the lesion area per unit area) in the field, 11 normal cytoplasmic maize inbred lines Column hybridization analysis of the disease level and three levels of genetic resistance genetic factors. Combine force was analyzed by Griffiug’s method 2 [P (P + 1) / 2] mode I. The results showed that the variance of general combining ability and the special combining ability reached the extremely significant level (P = 0.01), indicating that additive and non-additive genotypic efficiency
