【摘要】 采用灰色系统理论 ,构造高油授粉者理想型作为参考组合 ,对多种高油杂交种类型进行分析 ,并对筛选出的高油授粉者和不育单交种进行三利用模式组配。结果表明 :1灰色系统理论具有所需样本少、结果直观明确的优点 ,适合理想高油授粉者的初步筛选 ;2提出的高油授粉者理想型比较符合生产实践 ;3超高油单交种、高油单交种、高油三交种是合适的授粉者类型 ;4已选育出一批含油率接近高油 115的 TEU掺和种更多还原

【Abstract】 The ideal type of high oil pollinator (HOP) as reference corn cross, many kinds of hybrids were selected as HOPs by using grey system theory, and the effects of blending HOPs into CMS hybrids were evaluated. The results show that: ① Grey relation analysis has many favorable benefits of use, such as fewer samples, convenient calculation and visible results and is suitable to be used for screening HOPs;②The concept of ideal type of HOP is much more in line with production practices; ③ (Super) high oil single cross hybrid and high oil three way cross hybrid are all appropriate types for breeding HOPs; ④A series of seed blends have been selected, whose oil content are close to that of Gaoyou 115(one popular high oil single cross hybrid).更多还原
