We analyzed fruit and seed sets after self-pollination in 3 apple cultivars. Between 1998 and 2001, we carried out self-pollination of cultivars ‘Megumi’, ‘Orin’ and ‘Fuji’, which exhibit different le...
河流型水牛与沼泽型水牛杂交后代(2n=49) 染色体遗传与繁殖力的研究Studies of Chromosomal Heredity and Fertility of Progenies (2n=49) Crossed between River and Swamp Buffalo
三品种杂交水牛 2n=49核型 染色体分离 繁殖力 异常配子
2007/12/30
摘要通过2n=50和2n=49两种核型三品种杂交水牛繁殖记录分析和其中2n=49三品种杂交水牛联会复合体及其精子染色体研究，结果表明，后者虽然公母都是可育的，由于它产生两种正常配子（n=24，n=25）和两种异常配子（n=24+1，n=25-1），自群繁殖导致其子代染色体多态性（2n=50，2n=49和2n=48）；其异常配子，与正常配子结合，则产生非整倍性，致其繁殖力降低，表现为情期配种受胎率降...
