摘要
在贵杂四号杂交制种适宜播期条件下,通过不同父母本行比和行位试验研究结果表明:父母本行比为1∶6、行位为南北向的制种产量最高(48.56 kg/667m2),较其余处理显著或极显著增产,其产量构成较其它处理更为合理,易获得更高的制种产量。
The experiment was conducted to investigate effects of different row ratio between male and female parents and row orientation on seed yield of Guiza 4 under the rational seeding time. The results showed that the highest seed yield （48.56 kg/667m^2） could be gained when the row ratio between male and female parents was 1 ： 6 and the row orientation was northsouthward and the seed yield was significant and very significant higher than other treatments because of its rational yield composition.
