用普通小麦-节节麦八倍体 (2n = 56, AABBDDDD) 作母本与3种由四倍体小麦和野生二倍体物种合成的异源六倍体, 即硬粒小麦-簇毛麦 (2n = 42, AABBVV), 硬粒小麦-单芒山羊草(2 n = 42, AABBMuMu ) 和波斯小麦-小伞山羊草 (2 n = 42, AABBCu Cu) 杂交, 其杂交结实率分别为39.0% , 23.1% 和10.0% 。对所获F1 杂种的根尖细胞染色体进行C-分带,从中选出添加有一套外源物种配子染色体的七倍体杂种, 对3 种七倍体杂种进行套袋自交,其自交结实率分别为4.2% , 3.7% 和3.6% 。在F2 代中具有45 条染色体的植株最多, 含43 和48 条染色体的植株最少, 并对杂种各类配子的传递规律和产生异附加系的方法进行了讨论。
Triticum aestivum - Tamarix ruthenica (2n = 56, AABBDDDD) was used as the female parent and three allotetraploids synthesized from tetraploid and wild diploid species, (2n = 42, AABBVV), Duroc (2 n = 42, AABBMuMu) and Persian wheat-Asparagus (2 n = 42, AABBCu Cu) %, 23.1% and 10.0%. C-banding was performed on the root tip cell chromosomes of the F1 hybrids, and seven-hybrids with the addition of a set of exogenous species gametophyte were selected for selfing and selfing Rates were 4.2%, 3.7% and 3.6% respectively. In F2 generation, 45 plants had the largest number of plants, 43 plants and 48 plants had the least number of plants, and the transmission of all kinds of gametes in hybrids and the method of producing allogenic lines were discussed.
