应用微机进行小麦亲本选配和配置杂交组合的方法研究

Research on Application of Computer in Choice and Hybridization of Wheat Parents

将1987年70份亲本材料(8个性状)及1985年、1986年364个单交组合输入微机中建成数据库,并编写程序。该程序为BASIC语言,汉字提示,具有配置杂交组合、查找亲本、查找组合等功能。对所配组合进行跟踪调查表明,微机配的组合各世代入选率高,F_6对F_1的保留率达20％,而人工配的组合各世代入选率低,F_6对F_1的保留率仅为1.8％,微机配置的组合比人工配置组合的效率提高10倍,且利用微机配的组合选出了有苗头品系。

Data of 8 straits of 70 parents in 1987 and 364 single crosses in 1985-1986 were put into computer and a programme for research on parents and hybridizations was established. The programme had functions of choosing parents, making crosses and accumulating information on performance of them BASIC Language and Chinese character explanation were used in this programme, which was easy to learn and had a great practicability. The investigation on F6 lines showed that 20% of crosses made by computer was retained with comparison of 1.8% of crosses retained made manully. Some elite lines were selected from crosses made by computer.
