三个高蛋白与三个高脂肪品种进行完全双列杂交,研究以籽仁重、蛋白质和脂肪含量为主的15个性状的配合力、遗传相关及杂种优势.结果表明:两种配合力的方差分析F值均达显著标准,但加性效应占主要优势,总配合力与杂种实际表现高度相关.郑71—3是高产高脂肪的理想亲本,奇科可作为高蛋白材料加以利用.在性状间相关中,蛋白与脂肪为显著负相关,但二者与籽仁产量呈弱的正、负相关,有利高产高油分和高产高蛋白品系的选育.花生杂种一代有明显优势,但营养生长性状、结实性状和脂肪含量趋向高亲,而出仁率、百仁重和蛋白含量趋向低亲. Three high-protein and three high-fat varieties were completely diallel crossed to study the combining ability, genetic correlation and heterosis of 15 traits mainly including kernel weight, protein and fat content.The results showed that the two combining ability The F value of variance analysis reached a significant standard, but the additive effect accounted for the main advantage, and the total combining ability was highly correlated with the actual performance of the hybrid Zheng 71-3 was the ideal parent with high yield and high fat, and Chico could be used as the high protein material. There was a significant negative correlation between protein and fat in traits, but there was a weak positive and negative correlation between seed yield and yield, which was beneficial to high-yielding and high-yielding oil and high yielding high protein lines. Growth traits, fruit traits and fat content tended to be higher progenies, while kernel yield, protein content and protein content tended to be lower progenitors.
