【摘要】 随着人们对玉米异交不亲和性认识的不断深入,在国内外玉米育种及生产上,开始进行高配合力且性状优良的玉米异交不亲和系的选育,但是由于受到其本身异交不亲和的因素的影响,一些常规转育方法受到限制。对目前玉米育种中玉米异交不亲和性性状转育可行的三种方法进行比较研究,结果表明,在系谱株行选择法、单穗半分选择法和稀植单株双穗法这三种选择方法中,稀植单株双穗转育法是优良的玉米异交不亲和性性状的田间转育方法,在此方法中采用上位果穗做测交选择,下位果穗做自交留种的方式是单株双穗转育法中最好的技术手段。更多还原

【Abstract】 The Cross-incompatibility of Maize were breeding that were the high combining ability and the character fine Along with improving of level of understanding for The Cross-incompatibility of Maize in the domestic and foreign Maize breeding and the productions,but because receives its itself Cross-incompatibility factor the influence,some conventional Trans-breeding methods to be restricted.Three Trans-breeding methods of Cross-incompatibility of Maize were hereby studied.Finally indicated that Trans-breeding method of plants-thinly double-ear selection was the best in Pedigree strains of row selection,half of a Single ear selection and plants-thinly double-ear selection,and the plants-thinly double-ear is the field trans-breeding method,and it is the best technical means of plants-thinly double-ear selection in this method to test selection by using upper ear and to self-trans-breeding by using lower ear.更多还原
