- 摘要:
- 为促进优质、高产水稻新品种牡育稻49的推广，本文从其选育过程、品种特征特性、栽培技术、高效绿色试验示范等方面进行介绍。牡育稻49是黑龙江省农业科学院牡丹江分院以牡05-1205为母本，莎莎妮/明丰40为父本杂交，经系谱法选择育成。2020年7月通过黑龙江省农作物品种审定委员会审定，审定编号为黑审稻20200017。2017－2018年区域试验平均产量8 508.7 kg·hm-2，较对照品种龙稻5号增产7.8%；2019年生产试验平均产量8 148.5 kg·hm-2，较对照品种龙稻5号增产7.9%。牡育稻49生育日数139 d左右，适宜黑龙江省第二积温带≥10 ℃活动积温2 600 ℃区域种植。
- Abstract:
- In order to promote the extension of new rice variety Muyudao 49 with good quality and high yield,in this paper,the breeding process,variety characteristics,cultivation technology,high-efficiency green test and demonstration were introduced.Muyudao 49 bred by genealogy method is a new Oryza sativa Geng Group variety in cold region,derived from female parent Mu05-1205 and male parent Shashani/Mingfeng 40.It was approved by Heilongjiang Provincial Crop Variety Approval Committee in July 2020,and the variety approval number is Heishendao 20200017.The average yield of the regional trial was 8 508.7 kg·ha-1 in 2017 and 2018,which was 7.8% higher than that of the control variety Longdao No.5,and that of the production trial was 8 148.5 kg·ha-1 in 2019,which was 7.9% higher than that of the control variety Longdao No.5.Its growth days is about 139 days,and it is suitable for planting in the second accumulated temperature zone of Heilongjiang ≥10 ℃ active accumulated temperature 2 600 ℃.
