Abstract
To evaluate the yield and grain quality performance of rice varieties under rice-ratoon rice cultivation in northern Guangdong, a four-site field experiment was conducted from March to November of 2025 in Liannan and Lianshan counties of Qingyuan City and in Liucheng and Shangguan townships of Dongyuan County, Heyuan City, respectively. Seven rice varieties were evaluated: Qingxiangyou 19xiang (QXY), Nanjingxiangzhan (NJXZ), Jiangliangyouhuazhan (JLYHZ), Guiliangyou 6177 (GLY), Weiliangyouyuzhan (WLYYZ), Guiyouxinzhan (GYXZ), and Jiulixiang (JLX). The results showed clear differences in grain yield and grain quality among varieties and ecological sites. QXY generally showed the highest grain yield, especially in the ratoon crop, and ranked first in annual grain yield among the four sites, with values ranging from 10.26 to 11.63 t ha−1. However, the quality advantage differed among sites and varieties. JLYHZ showed the best quality performance in Lianshan County and Dongyuan County (Shangguan Township), GLY showed the best quality performance in Liannan County, and JLX showed the best quality performance in Dongyuan County (Liucheng Township). These results indicated a yield–quality trade-off among the tested varieties. Therefore, QXY may be considered a promising yield-oriented variety for the tested sites in northern Guangdong, whereas JLYHZ, GLY, and JLX may be more suitable where grain quality is prioritized.
