In the regional trial of Hubei Province in 1991, its yield was 4.4% higher than that of the CK Weiyou 48-2, being significant at 0.05 level. In the same year, in another regional trial of Sichuan Province, its yield was 8.9% higher than that of the CK Weiyou 48-2, being significant at 0.01 level. It has the highest yield among all tested varieties in both provincial trials. It has shown good grain quality with 60% head rice recovery and moderate resistance to rice blast.展开更多

Its average yield in two-year provincial production trials was 9.53 t/ha, 15.2% higher than the CKs Liaoyan 5 and Fengjin, respectively. Liayannuo is of moderate resistance or resistance to blast, bacterial blight of rice, sheath and culm blight of rice, rice aspergillus, response to fertility and endurance to saline and alkaline, drought and cold temperature.展开更多
