Study on microspore culture of the hybrids between Chinese cabbage and turnip
Microspores of six hybrids between non-headed Chinese cabbage(Brassica campestris ssp. chinensis) and turnip (B. campestris ssp. rapifera Matzg) were cultured . The embryoid yield varied with the different materials used, and the two genotypes with the highest embryoid yield, B. campestris ssp. chinensis cv. aijiaohuang and shuzhouqing crossed with B. campestris ssp. rapifera Matzg cv. qisihai produced 21.2 and 17.2 embryoids per flower bud. The optimum period of inducing embryo was uninucleate period. Preheat of 33 ℃ for 24 h before the microspores were transferred to the culture condition of 25 ℃ could obviously enhance the yields, and the active carbon could improve embryo quality.
