Production method of germplasm resource of ornamental flowering Chinese cabbages

Abstract

A production method of a germplasm resource of ornamental flowering Chinese cabbages is characterized by comprising steps as follows: a conventional variety of common cabbages, that is, Suzhongqing Q8, used as a female parent and Guangdong cabbage selfing line G1 used as a male parent are hybridized to form first hybrid generation seeds F1; first hybrid generation seeds F1 have selfing to form F2; single plants with shortest petioles are selected from F2 to have selfing to form F3; single plants with compact plant types, short petioles and small leaves are selected from F3 to have selfing to form F4; single plants with compact plant types, short petioles, small leaves and glossy dark green cabbage color are selected to have selfing to form F5; single plants with compact plant types, short petioles, small leaves, glossy dark green cabbage color and short joints are selected to have selfing to form F6; single plants with compact plant types, short petioles, small leaves, glossy dark green cabbage color, short joints and upright leaves are selected to have selfing to form F7; single plants with lotus-throne-shaped leaf clusters, unobvious base jointing during cabbage drawing, short stems, long flowering period and large flower amount are selected to has selfing to form F8. The ornamental period of the germplasm leaves and flowers of the ornamental flowering Chinese cabbages is 40-60 days, leaves and flowers can be enjoyed during the New Year's Day and the Spring Festival, the flower amount is large, and the ornamental effect is good.

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
