以4个常用自交系作母本,5个经过EMS化学诱变处理并经多代自交纯合的材料作父本,按NCII设计配成20个杂交种,研究了其中3个品质性状的杂种优势表现。结果表明:①杂交种在脂肪含量上的平均表现介于雌亲平均数和雄亲平均数之间;在淀粉含量上既低于雌亲平均数又低于雄亲平均数;在蛋白质含量上既高于雌亲平均数又高于雄亲平均数;②离中优势较为普遍,有53.3%的性状-组合存在显著的离中优势,尤其是蛋白质含量,离中优势显著的组合达85%;③有18.3%的性状-组合存在显著的超高亲优势,有11.7%的性状-组合存在显著的超低亲优势;④在蛋白质含量上,材料M04003、M04008、M04010所配制的组合几乎都表现出超亲优势,为较好组合。
Four common inbred lines were used as female parent, five were chemically mutagenized by EMS and were self-fertilized and homozygous for many generations. Twenty hybrids were designed according to NCII design. Three quality traits Heterosis performance. The results showed that: ① The average performance of hybrids in the fat content ranged from the average number of females to the average number of males; the starch content was lower than the average number of females and the average number of males; the protein content of both Higher than the average number of females and higher than the average number of males; ② advantage from the more common, with 53.3% of traits - there is a significant combination of advantages from the center, in particular, the protein content, from the superiority of the combination of up to 85%; ③ 18.3% of the traits - the combination of significant super high pro-dominant, 11.7% of the traits - the combination of significant low pro-dominant advantage; ④ protein content, the material M04003, M04008, M04010 prepared combinations almost all showed super Pro-dominant, for a better combination.
