七十年代我省为选育亩产800斤的迟播早熟品种,曾以“阿波”的高产稳产结构为基础进行分析与设想,把降低株高,限制叶量与提高穗数结合起来;把利用品种特性,提早穗子分化,延长小穗分化期,与多花多粒结合起来,使提高穗数与保持穗重得以统一。根据这些设想提出了矮秆、多穗、多粒的选育方向。这一时期在继“繁六”、“繁七”、“980—16“、“川育5号”等之后,又先后选育出“绵阳11号”、“川育6号”、“1190—1”、“77—2753”等品种。它们有的已在大面积生产上应用,有的正在扩大推广,有的还在参加区域性鉴定。这些品种的高产潜力接近或略高于“繁六”,其产量水平在大面积上可稳定在700—750斤/亩,小面积可达800斤/亩左右。这是进一步
Seventies in our province for the selection of 800 kg per mu yield of late sowing precocious varieties, once ”Abo“ high yield and stable structure as the basis for analysis and imagination, to reduce plant height, limiting the amount of leaves and increase the number of spikes; The use of species characteristics, early ear differentiation, to extend the spikelet differentiation period, combined with the flowering and more grains, to improve the number of spikes and to maintain the weight of the ears to be unified. According to these ideas, we proposed the breeding direction of dwarf, multi-spike and multi-grain. During this period, following the success of ”Fanliu“, ”Fanqi“, ”980-16“ and ”Chuanyu 5“, he successively produced ”Mianyang 11“, ”Chuanyu 6“ and ” 1190-1 “,” 77-2753 “and other varieties. Some of them have been applied in large-scale production, some are expanding their promotion, and some are still participating in regional appraisal. The high yield potential of these varieties is close to or slightly higher than that of ”Fanliu", and its output level can be stabilized at a large area of 700-750 kg / mu and the small area can reach 800 kg / mu. This is further
