摘要
南粳盐1号是江苏省农业科学院粮食作物研究所以沈农9903为母本、耐盐粳稻品种盐丰47为父本杂交,于2017年育成的一个优质、早熟、综合丰产性好的耐盐粳稻新品种。该品种株型紧凑,群体整齐度好,抗倒性较强,全生育期148.8 d,比对照盐稻12号早熟2.7 d。南粳盐1号株高88.1 cm,穗长15.4 cm,有效穗数19.0万个/667 m^(2),总粒数123.3粒/穗,结实率86.8%,千粒质量25.5 g。2018—2019年2年的稻瘟病综合指数均为5.0,穗颈瘟损失率最高级均为5级,白叶枯病抗性2年最高级均为5级;2018年条纹叶枯病发病率为13.3%,表现为3级;2019年条纹叶枯病发病率为21.8%,表现为5级。2019年0.5%土壤盐浓度下苗期耐盐级别为5级,0.3%盐浓度下全生育期鉴定为3级。稻米品质达农业行业标准NY/T 593—2021《食用稻品种品质》2级。2021年通过国家农作物新品种审定委员会审定,审定编号为国审稻20210451,适宜在江苏省、山东省沿黄稻瘟病轻发的粳稻区土壤含盐量0.5%以下的盐碱地用淡水灌溉种植。
Nangengyan No.1 is a new salt-tolerant geng rice variety with good quality,early maturity,and a high-yielding ability.It was derived from the cross of Shennong 9903 as the maternal parent and Yanfeng 47,a salt-tolerant geng rice variety,as the paternal parent,and the breeding was conducted by Institute of Food Crops,Jiangsu Academy of Agricultural Sciences.Nangengyan No.1 has the characteristics of compact plant-type,good population uniformity,and strong lodging resistance.Its whole growth period was 148.8days,which was 2.7 days earlier than that of the control rice variety Yandao 12.It had the plant height about 88.1 cm,the panicle length of 15.4 cm,the effective panicle number about 190000/667 m^(2),the total grain number per panicle of 123.3,the seed setting rate of 86.8%,and the 1000-grain weight of 25.5 g.It showed moderate susceptibility to rice blast disease,stripe disease,and bacterial blight.It had strong salt tolerance that reached level 5 under 0.5%salinity treatment in seedling stage and reached level 3 under 0.3%salinity treatment during whole growth period.Its grain quality reached the standards of the second class of the Quality of Edible Rice Varieties(NY/T 593—2021).Approved by National Variety Appraisal Committee of China in 2021,Nangengyan No.1 is suitable for growing in lands with a soil salt content lower than 0.5%in the northern area of Jiangsu Province and the area along Yellow River in Shandong Province.
