Abstract: The characteristics of 8 hybrid rice varieties series of‘Minhui 3301’registered in Fujian province were analyzed in this paper to investigate their yield potential and conduct further research on the breeding of high quality-yield hybrid rice varieties. The results showed that: the heavy panicle rice varieties, including the medium rice varieties‘Hua2you 3301’‘, Minfengyou 3301’‘,Ⅱyou 3301’and‘Quanyou 3301’, all had high yield advantages in grain number per panicle (174.0 to 220.5), 1 000-grain weight (28.9 to 30.2 ) and single panicle weight (4.39 to 5.19 ). The late rice varieties‘Tianyou 3301’,‘Guyou 3301’,‘Lianyou3301’and‘Taifengyou 3301’belonged to the panicle-kernel rice varieties. Among the 8 rice varieties,‘Guyou 3301’had better resistance to rice blast. Chalkiness and chalky rice rate were the main influence factors on grain quality. In future cultivation of hybrid rice, it is important to highlight regional distribution and cultivation techniques, give consideration to chalkiness, chalky rice rate and improve the resistance of hybrid rice to rice blast.
