A method for creating germplasm resources of ornamental cabbage sprouts

Abstract

A method for creating germplasm resources of ornamental cabbage, which is characterized in that it includes the following steps: taking Suzhouqing Q8, a conventional variety of common Chinese cabbage, as the female parent and Guangdong Caixin inbred line G1 as the male parent, and crossing the two to obtain the first generation of hybrid seeds F1; F2 is obtained by self-crossing F1 of the first generation; F3 is obtained by self-crossing the single plant with the shortest petiole length in F2; F4 is obtained by self-crossing the single plant with compact plant type and short petiole and small leaves in F3; plant type selection F5 was obtained by self-crossing a single plant with compact, short petiole, small leaves, and dark green stalk; F6 was obtained by self-crossing a single plant with compact plant shape, short petiole, small leaves, dark green stalk, and short nodes; F7 is obtained by selfing a single plant with short and small leaves, oily green stalk color, short nodes and erect leaves; select a single plant with rosette-shaped leaf clusters, no obvious jointing at the base when bolting, short stems, long flowering period and large flower volume. Get F8. The leaf and flower viewing period of the ornamental vegetable stalk germplasm of the invention is 40 to 60 days, can enjoy leaves and flowers during New Year's Day and Spring Festival, has a large amount of flowers, and has good ornamental effect.

Description

technical field [0001] The invention relates to the field of flower breeding, in particular to a method for creating germplasm resources of ornamental cabbage sprouts. Background technique [0002] In terms of plant taxonomy, cabbage belongs to Brassicaceae Brassica species Brassica non-heading cabbage subspecies cabbage variety, also known as cabbage heart, cabbage tip, and cabbage mustard. The edible organs are flower sprouts and attached sprout leaves, which are the original The characteristic vegetables produced in our country are one of the types of vegetables that ordinary people like to eat. Ornamental vegetable sprouts, as the name suggests, are vegetable sprouts selected for the main purpose of viewing, and are generally edible. [0003] Suzhou is located in the lower reaches of the Yangtze River. Although there has been a trend of warmer winters in recent years, sometimes the lowest temperature can still reach -7°C. There are few types of herbal flowers that can b...

AI Technical Summary

Problems solved by technology

Using common Chinese cabbage variety Suzhouqing Q8 and Guangdong Caixin inbred line G1 as parent materials, using conventional cross-breeding techniques and pedigree selection methods, not only gathered a variety of known excellent traits of the parents, but also gathered a variety of traits that the parents did not show. It can be used as an excellent ornamental trait, and a basic germplasm material that can be used as an ornamental cabbage breeding has been created, which can solve the lack of herbaceous flower varieties that bloom naturally in winter in the middle and lower reaches of the Yangtze River and the lack of flowering varieties of existing natural flowering varieties in winter. Problems such as single color and small amount of flowers
