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.
