摘要

采用自然加倍和秋水仙碱+DMSO化学加倍的方法，对京可诺2000、克念1号、皖诺2000、冀可诺99和冀可诺20 5个糯玉米杂交种的单倍体种子进行了处理。结果表明，京科诺2000、万诺2000、克年1号、吉科诺20和吉科诺99的平均加倍率分别为0.30%、0.18%、0.53、1.30和1.05%。在不同生态环境下，南滨试验场的单倍体加倍率均高于双阳试验场。不同加倍方法的单倍体加倍率不同。结果表明，针刺生长点法的加倍效果略好于浸泡芽法，但差异很小，可以灵活使用。对于不同浓度的秋水仙碱溶液，0.08mg/l溶液对糯玉米单倍体的加倍效果最好，平均加倍率为7.96%，最高加倍率为10.70%。Bangladesh J.Bot.52（2）：523-5282023（June）Special

Haploid doubling effect of waxy maize under different ecological environment

The haploid seeds of five waxy maize hybrids, Jingkenuo 2000, Kennian 1, Wannuo 2000, Jikenuo 99 and Jikenuo 20, were treated with natural doubling and colchicine + DMSO chemical doubling. Results showed that the average doubling rates of Jingkenuo 2000, Wannuo 2000, Kennian 1, Jikenuo 20 and Jikenuo 99 were 0.30, 0.18, 0.53, 1.30 and 1.05%, respectively. The haploid doubling rates of Nanbin test site were higher than those of Shuangyang test site under different ecological environment. The haploid doubling rates of different doubling methods were different. Results showed that the doubling effect of needling growth point method was slightly better than that of soaking bud method, but the difference was very small, so it could be used flexibly. For different concentrations of colchicine solution, 0.08 mg/l solution had the best doubling effect on the haploid of waxy maize, with an average doubling rate of 7.96%, and the highest doubling rate of 10.70%.

期刊介绍： Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments. Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December. Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
