以7个旅系与2个外杂选系组配的14个组合和对照种郑单958为材料,采用随机区组设计,3次重复试验,分析由旅系组配的组合产量、抗性、农艺性状和考种性状与对照间的差异。结果表明,旅系的产量一般配合力较高,抗性、穗粗和穗长等方面优于对照,但耐密性、抗倒性、封顶性、子粒深度、含水量和出籽率等方面与对照还有差距,且生育期长于对照。
A total of 14 combinations and 7 types of Zhengdan 958 with 7 foreign lines and 2 foreign lines were used as materials. Randomized block design and 3 replicates were used to analyze the combined yield and resistance , Agronomic traits and test variety and control of the difference between the characters. The results showed that the tourism output was higher than that of the control in terms of general combining ability, resistance, ear diameter and spike length, but the characters of tolerance, lodging resistance, captivity, depth of seed, water content and seed yield There is a gap with the control, and the growth period is longer than the control.
