用6个玉米自交系进行双列杂交,共15个单交组合,通过估计一般配合力和特殊配合力效应,研究了这些自交系对茎腐病、穗腐病、黑粉病、丝黑穗病的抗性遗传。在匈牙利的毛尔通瓦沙尔,人工和自然接种条件下评价了这些试材。在收获时期根据1～9级的分级等级,在每一小区逐株记载茎腐和穗腐病的发病率。黑粉病和丝黑穗病则调查每一小区完全成熟植株的病株百分率。试验按完全随机区组设计,
A total of 15 single crosses were crossed with 6 maize inbred lines. By estimating the general combining ability and the special combining ability, the effects of these inbred lines on stalk rot, ear rot, smut, silk Hertzian inheritance of resistance. The samples were evaluated under manual and natural inoculation in Huntsville, Hungary. At the harvesting stage, the incidence of stem rot and ear rot was recorded in each plot according to the grading scale of 1 to 9 levels. Smut and silk smut were investigated for the percent of diseased plants in fully mature plants in each plot. The trial was designed according to a completely randomized block design
