摘要 介绍了杂交水稻赣优明占品种的特征特性.并对其产量构成因素的相关及对产量的贡献进行分析,明确4个产量构成因素中,每穗总粒数与产量的关系最密切,次为有效穗数,结实率、千粒重与产量的密切程度较低.每穗总粒数对形成产量的贡献率最大(Pr=0.5141),次为每穗总粒数(Pr=0.3913),每穗总粒数与有效穗数对产量的贡献率之和达90.54%.据此提出赣优明占高产栽培主要策略:培育足够有效穗的基础上争大穗多粒. This paper summarized characteristics of Ganyoumingzhan and analyzed yield forming factors and their contribution rate to yield, results showed among the 4 factors, total spikelet per panicle has most close correlation with yield, followed by effective panicle, seed setting rate and 1000-grain weight have lower correlation. Total spikelet per panicle was the biggest rate of contributed factor to rice yield ( Pr =0.5141 ) , the following was effective panicle ( Pr=-0.3913 ) , both of which take account for 90.54%. Therefore, this paper proposed the strategy of high production cultivation of Ganyoumingzhan that realize large panicle with more spikelets on the basis of sufficient population.
