Abstract

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.

Key words: hybrid late-maturing japonica rice, new varieties, grey comprehensive evaluation, screening
