Analysis on Combining Ability and Utilization of Major Agronomic Characteristics in Hybrid Rice Combination
摘要
Abstract
An analysis on the combining ability of the agronomic characters of 6 male sterile lines(Quan-fengA, GufengA, TianfengA, Guangkangl3A, Rongl8A and Ⅱ - 32A) and 5 restorer lines ( YRL577, YR2292,YR3003,YR4245 and YR7633)of 30 hybrids were conducted by means of incomplete diallele cross (NCⅡ design). The agronomic characteristics of Fl generation were analyzed, The results showed that the specific combining ability (SCA) of panicle length (PL) , spikelets panicle number (SN) , seed setting rate (SSR) , 1000 -grain weight(GW) and the grain weight of per plant(GWP) was higher than that of general combining ability (GCA) , which indicated that most of the characters were mainly affected by non - additive effect; the characters of panicle length, effective panicle number ( EPN) , full spikelets panicle number (FN) , spikelets panicle number, 1000 - grain weight were influenced by restorer lines more greatly than by sterile line. Considering their combining ability and heritability, Guangkangl3A/YR7633 and E - 32A/ YR2292 are high-yield hybrid combinations.关键词
