摘要
[目的]介绍早籼615的选育与栽培技术。[方法]早籼615由安徽省农业科学院水稻研究所于1999年以早籼14为母本、Y134为父本进行杂交,通过系谱选择法选育而成。描述了该品种的产量表现、特征特性和栽培要点。[结果]早籼6152007～2009年连续2年参加安徽省早籼区域试验,平均产量7419.8kg/hm2,较对照竹青增产8.12%;2009年参加安徽省早籼生产试验,平均产量7243.8kg/hm2,较对照竹青增产9.12%。该品种株型较紧凑,茎秆较粗壮;中抗白叶枯病和稻瘟病,苗期耐寒能力较强;米质较好,综合指标达4级食用稻品质标准。[结论]该品种具有产量较高、米质较好、抗性较强、生育期适中的特点,在安徽省双季稻区具有广阔的推广利用前景。
[Objective]The study aimed to introduce the breeding and cultivation technique of an early indica rice variety Zaoxian 615.[Method]Zaoxian 615 was bred by using the pedigree method through the cross between female Zaoxian 14 and male Y134 by Rice Institute,Anhui Academy of Agricultural Sciences.The yield performance,variety characteristic and main cultural technique of the variety were described.[Result]In continuous 2-year participation of early indica rice variety area trial from 2008 to 2009 in Anhui Province,Zaoxian 615 had the average yield of 7 419.8 kg/hm^2,8.12% higher than CK variety Zhuqing;in the participation of early indica rice prodction trial in 2009,Zaoxian 615 had the average yield of 7 243.8 kg/hm^2,9.12% higher than CK variety Zhuqing.The variety was characterized by the compact plant type,stronger stem,the moderate resistance to rice blast and bacteria leaf blight and stronger tolerance to low temperature at seedling stage.Its grain quality was better,with the comprehensive indicator meeting the 4th grade of rice quality standard issued by Ministry of Agricultural of China.[Conclusion]Zaoxian 615 has characteristics of high yield,good grain quality,strong resistance and moderate growth,so it shows the wide prospect of generalization and utilization in double-season rice area of Anhui Province.
