In the present research, we aimed to detect and evaluate the level of long terminal repeat (LTR) retrotransposons (WIS2, Wilma, Daniela, and Wham) intraspecific variability and intron polymorphism for...
中国春(T.aestivum)与黑麦(Secale cereale)可交配性基因与Ta1基因的关系。
黑麦(Secale cereale)的染色体组型分析
黑麦
2008/1/4
本试验用涂片法制片,以低渗、酶解、火焰干燥以及分带等处理我国“甘肃黑麦”和加拿大黑麦“Kustro”的根尖细胞。从形态、C 带带型分析和比较了其染色体组型。两个品种无显著差异。其染色体的端粒带、核仁缢痕带都显著而较稳定。着丝点带也常出现。中间带变化较大。所有染色体分为三组:中部着丝点染色体;亚中部着丝点染色体;随体染色体。
摘要ph2a。用中国春回交F_1取得了成功,回交结实率分别为1.06％、0.73％、2.52％和11.40％。利用ph1b、ph2b基因可以将黑麦中有益基因直接遗传转移给小麦,ph2a在导入黑麦有益基因方面不宜利用,或其效果不及ph1b、ph2b,回交结实率与染色体配对有关。
