Abstract

This paper introduces the breeding procession,agronomy characteristics and cultivations of early-season hybrid rice Jinyou 152.It's yield potential is about 7 500 kg·hm-2.Jinyou 152's yields are 0.05%～21.90% higher than control,Boyouzhan19,in variey comparing and regional tests.Its rice qualifies the second grade high-quality rice according to the high-quality rice standards of the Agricultural.Ministry of China.Seeding at proper time and density,enough base fertilizer,transplanting at proper time and density are necessary to get high yield.
