棉花组织培养植株再生的基因型分析

Genotype Analysis in Cotton Tissue Culture and Plant Regeneration

棉花组织培养体细胞胚胎发生和植株再生是由多基因控制的数量遗传性状，该性状可通过系统选育或杂交育种的方式传递给后代。美国的珂字棉、原苏联的１０８夫、澳大利亚的Ｓｉｏｋｒａｌ１－３和国内的冀合３２１、鲁棉系列较易获得体细胞再生植株；原苏联、澳大利亚、中国棉花组织培养较易成功的品种大多是由美国珂字棉通过系统选育或杂交育种而获得的。在棉花组织培养中。

Cotton somatic embryogenesis and plant regeneration was a genetic character that was controled by many genes, the character could transfered into progeny by system breeding or cross breeding. The varieties that was easy to obtain regenerative plants were Coker cotton in USA, 108 φ in Soviet, Jihe 321 and Lumian in China, Sikral 1 3 in Australia. Most of the varieties that was easier to obtain somatic embryos and regenerative plants in Australia, Soviet and China came from the progeny of Coker cotton. The ablility of plant regeneration could be improved by conscious screening.
