摘 要 ：从株高平均、超亲优势、回归和配合力等方面,比较不同矮秆系的致矮力。并对控制玉米矮生性的基因类型及微效多基因矮秆系的基因效应和基因对数进行了研究。结果表明,在本研究所用材料中,以隐性单基因矮秆系出现的频率最低,微效多基因矮秆系次之,而大部分矮秆系则是隐性单基因和微效多基因的重叠效应系。当这些矮秆系与中、高

Abstract:The dwarfing abilities of different dwarf-lines of maize were compared according tomean plant height,heterosis,combining ability and regression.And the types of genes thatcontrol the dwarfness in corn,number of alleles and their gene effects of minor polygenedwarf-lines were identified as well.The r
