摘　　要：申优28是以BT型不育系申21A与恢复系申恢26-28配组育成的三系杂交粳稻新组合。申优28制种时,通过调节双亲的生长发育,确保了父母本花期高度相遇。研究了父母本均机插条件下不同父母本行比及母本株距对申优28制种产量的影响,以及在父本机插(行距25cm)-母本机直播(行距20 cm)条件下,母本不同株距对申优28制种产量的影响。结果表明,在父母本均机插条件下,父母本行比2︰8~10、行株距25 cm×14 cm时制种产量高;父本机插-母本机直播条件下,以株距16 cm时制种产量高。通过以上优化栽培方式,确保了杂交粳稻制种高产高效。Shenyou 28 is a new three-line japonica hybrid rice combination developed by combining BT-type male sterile line Shen21A and restorer line Shenhui 26-28.During the seed production process of Shenyou 28,a high level of meeting between parents at flowering period were obtained by regulating the growth and development process of both parents.We studied the effects of different row ratios and row spacing of female parent on the yield of Shenyou 28 seed production under the condition of both male and female parents being mechanically transplanted,and the effects of different plant spacing of female parent on the yield of Shenyou 28 seed production under the condition of all-in-one machine of male parent machine transplanted(line spacing of 25 cm)and female parent machine direct seeding(line spacing of 20 cm).The results showed that under the condition of parents both mechanically transplanted,the seed production yield was higher when the row ratio of parents was 2∶8-10,and the row spacing was 25 cm×14 cm.Under the condition of male parent machine transplanted and female parent machine direct seeding,the seed production yield was higher when the plant spacing of 16 cm.Optimizing the cultivation methods mentioned above can ensure high yield and efficiency in hybrid japonica rice seed production.
