Abstract:

The aim is to compare the characteristics of a large number of kale varieties and their characteristics of flowering and seed setting, screen out the excellent varieties, clarify the current seed production pathways of kale and provide references for the targeted introduction, separation and utilization of the varieties. At the same time, the seeds of the introduced offspring can be further utilized to innovate resources. A total of 28 kale varieties from home and abroad were collected as samples to compare the field comprehensive traits and flowering and seed setting characteristics. At present, compared with foreign varieties, China’s domestic kale varieties have been greatly improved in terms of comprehensive characteristics, some varieties even surpass foreign varieties and can be widely promoted. Among the 28 materials, 20 are fertile and 8 are infertile, and 6 of the infertile varieties are from domestic Jingyan series. It indicates that the current kale seed production mainly adopts the self-incompatibility pathway, and China has taken the lead in using the male sterile.

Key words: Brassica oleracea var. acephala, plant characteristics, flowering and seed setting characteristics, breeding
