摘要
采用不完全双列杂交试验法,通过对6组资料71个亲本183个组合分析了甜菜近交系两种配合力在F_1的表现。结果表明,甜菜杂交种一般配合力对F_1产质量的相关性比特殊配合力更密切,即一般配合力对F_1产质量的贡献大于特殊配合力。在优产质量组合部分表现得更加明显,配合力的结合类型也是选择的适宜指标。理想的一般配合力结合模式应为:高×高或高×中类型.
This test conductcd with incomplete diallel crosses method,and andlysis on the combineability of inbred line and hctero tic exprcasion of F_1 with 183 combinations in 71 parentswhich dividcd into 6 groups,the results have shown that GCA of the yield and quality of F_1in corrclation were more close than SCA, and it was more signiricant in the fine yield andquality combinations,the optimum targets for selecttion is the combined type of combine abili-ty,the perfect model of GCA is: High×high or High×middle.
