Problems solved by technology

[0003] Regarding the quality breeding of Chinese cabbage, in the past due to the limitation of manpower, conditions and other factors, there were few domestic and foreign researches for many years. It is a by-product obtained by crossing Chinese cabbage and turnip during the breeding of clubroot-resistant materials. However, due to the poor quality, the color is easy to change during processing, and the promotion area has not been large so far.
At that time, our country also introduced several times, but it was very unsuitable to the climate conditions in Beijing. This variety had poor resistance to viral diseases and poor quality, so it could not be directly used.

Embodiment Construction

[0019] Describe the embodiment of the present invention below:

[0020] The present invention uses 902361 as the female parent and 91545 as the male parent to prepare the first-generation Beijing Juhongxin hybrid.

[0021] 1. Key points of seed production technology:

[0022] First of all, pure hybrid seeds of the first generation must be prepared at the isolation point in spring, and the breeding requirements must be strictly followed. Generally, in Beijing, seedlings are sown at a staggered time in protected areas (sun beds or greenhouses) from late December to early January (parent 902361 is earlier than 91545) Sow for 10 days), separate the seedlings with 2 to 3 true leaves, and plant 7 to 8 true leaves (in the middle and late March) in the open field. It is best to use mulch when planting. The planting density can be controlled at about 4000 plants, and seed collection is required The point is more than 1,000 meters away from the surrounding cruciferous crops that are ea...

Abstract

The present invention breeds first-filial generation of Beijing Chinese cabbage with reddish orange core by using Chinese cabbage 902361 as female parent and Chinese cabbage 91545 as male parent. Theseeding period difference is 10 days with the female parent being seeded earlier and the seedling spacing between the female parent and the male parent is over 1000m. The hybrid Chinese cabbage has reddish orange core, disease resistance higher than that of imported Japanese species, high quality and high yield.

Description

Technical field: [0001] The invention belongs to the technical field of crop heterosis utilization, and in particular relates to a cabbage heterosis utilization technology. Background technique: [0002] Chinese cabbage is native to my country, rich in resources, and has a long history of cultivation. In addition to China, there are many countries that grow Chinese cabbage in the world, including Japan, North Korea and Southeast Asia. The country that studied Chinese cabbage earlier in the world is Japan. As early as the 1950s, it was engaged in the research on the use of heterosis in Chinese cabbage. In 1966, the first generation of Japanese Chinese cabbage hybrids was popularized throughout the country. Our country has been engaged in Chinese cabbage selection for a long time, but in the past it was mainly limited to the general selection of folk vegetable farmers. Over the years, many local varieties suitable for local ecological types have been formed in various parts o...
