Relationships between Panicle Traits and Yield Components in Rice

AbstrcatUsing the main varieties and region test ones altogether 33 rice varieties of LiaoNing province, the relationships between panicle traits and yield components were analyzed.The results showed that grain yield was closely correlated with panicle numbers,grains/panicle and spike setting density affect grain yield significantly, because panicle numbers and grains/panicle contributed to yield improvement while spike setting density have a negative effect on it.
