- 摘要:
- 对普通小麦与中间偃麦草远缘杂交后代中选育的八倍体小偃麦—麦草9号进行了形态学和细胞学鉴定。结果表明：麦草9号植株高大，结实性较好，籽粒饱满，生长旺盛；根尖细胞染色体数目为2n=56，对其进行花粉母细胞减数分裂观察，中期Ⅰ具有一定数量的单价体、环状二价体、棒状二价体；后期Ⅰ、后期Ⅱ与四分体时期都出现不同数量的落后染色体、染色体桥、微核等现象。这些现象表明中间偃麦草的 E组染色体进入了普通小麦的基因组，影响ABD组染色体配对。
- Abstract:
- Morphological and Cytogenetics of octoploid trititrigias-Maicao No.9，distant bred from the progeny of common wheat and thinopyrum intermedium were studied.The result showed that the plant of Maicao No.9 was tall，with good fecundity，fully filled grain and vigorous growth.The chromosome number of the root cells was 2n=56，through the observation of pollen mother cells meiosis，there were a certain amount of univalents，ring bivalents and bar bivalents in PMCM.Different numbers of lagging chromosomes，chromosome bridges and micronucleus were found in anaphaseⅠ，anaphaseⅡ and tetraspore.Those showed that the Echromosome of thinopyrum intermedium inserted the genome of common wheat，and it disarranged the original matching of chromosome.
