Abstract

Abstract: The pollen mother cells(PMC) meiosis of BC₁ derived from allotriploid(AAC) and diploid Chinese cabbage(AA) were studied,and both farm characteristics and pollen character of BC1 were evaluated at reproductive stage,using diploid Chinese cabbage(codenamed 85-1,2n = 20) as a control. The results showed that the chromosome division during PMC meiosis appeared complicated. Multi-synapsis types(8Ⅱ + 2Ⅲ,10Ⅱ + 2Ⅰ,9Ⅱ + 1 Ⅲ + 1Ⅰ) were observed at diakinesis stage. Single or a few isolated free chromosomes were funded during metaphaseⅠ andⅡ. The frequency of chromosome lagging or losing was very high during anaphaseⅠandⅡ. The results mentioned above may be the main reasons which caused a variety of ways of chromosomes separation. There were a few valuable gametes with 11 chromosomes appeared. In addition,field observation showed that both the growth vigor and pollen quantity or viability of a2 were weaker or lower than that of 85-1. A2 had smaller leaves,flowers and flower buds,and had earlier bolting and flowering trait,comparing with 85-1. All the results mentioned above provided a theoretical basis for progeny planting population setting up and regulating flowering date in cross-breeding of Chinese cabbage.
