摘要
对 30 个杂交晚粳稻新品种进行单晚栽培筛选,并用灰色综合评判法对 8 项性状进行综合评判,结果表明:甬优 1540、甬优 12 等 10 个品种的灰色综合评判值(G)>0.65,为优等品种;甬优 69、甬优 15 等 11个品种的 G介于 0.60~0.65,为良等品种;甬优 7826、甬优 1516 等 9 个品种的G<0.60,为差等品种.据此,提出甬优 1540、甬优 12、甬优 7850 等 10 个综合性状优良品种可在浙北嘉兴生产应用.
Abstract
Cultivation screening was conducted on 30 hybrid late-maturing japonica rice varieties,and a comprehensive evaluation of 8 traits was carried out using grey comprehensive evaluation method.The results showed that 10 varieties,including Yongyou 1540 and Yongyou 12,had G values greater than 0.65,indicating excellent quality;11 varieties,including Yongyou 69 and Yongyou 15,had G values ranging from 0.60 to 0.65,indicating good quality;and 9 varieties,including Yongyou 7826 and Yongyou 1516,had G values less than 0.60,indicating inferior quality.Based on this,it is proposed that 10 varieties with excellent overall traits,such as Yongyou 1540,Yongyou 12,and Yongyou 7850,can be used for production in Jiaxing,northern Zhejiang.
