Embodiment 1

[0022] Breeding of Example 1 Cytoplasmic Male Sterile Line 118A

[0023] (1) Breeding objectives: crisp and sweet taste, many branches, strong resistance and strong combining ability.

[0024] (2) Creation of breeding materials: A plant with light green leaf color, For plants with thin wax powder and many branches, the taste of cabbage shoots is very good through early adopters. They were bagged and self-bred during the flowering period of the year, and the quality inspection was carried out after harvest, which reached the double-low standard. The harvested seeds were planted in the autumn of 2005. Through observation, there was a separation phenomenon. In the spring of 2006, a single plant with good taste, many branches, and thin wax powder was selected for self-bagging, and the disease-free plants were harvested in the mature stage. Carry out quality testing; in the autumn of 2006, individual plants will be selected for branch planting, and in the spring of 2007, direction...

Embodiment 2

[0035] Example 2 Breeding of restorer line 927

[0036] (1) Breeding objectives: crisp and sweet taste, early growth and strong resistance.

[0037] (2) Breeding process: The female parent is Zhongshuang 11 (National Inspection Oil 2008030) bred by the China Oil Crops Research Institute, and the early-maturing new line P4 is used as the male parent, and it is produced by self-selection for multiple generations. . Among them, P4 is the female parent of Hui 5, the male parent of Xiangzayou 3 (Xiangpinshen 317) bred by Changde Agricultural Science Research Institute, and Zhongshuang 6 (Guojianyou 2003027) was crossed from the male parent, and then selected through continuous directional selection for 6 consecutive generations.

[0038] The specific breeding process of the restorer line 927 is as follows:

[0039] F0: In the spring of 2012, Zhongshuang 11 was used as the female parent and P4 was used as the male parent for crossing.

[0040] F1: In the spring of 2013, 10 plant...

Embodiment 3

[0048] Example 3 Breeding of Youtai 929

[0049] In the spring of 2016, 118A was used to prepare a hybrid combination with the new line 927, and the combination was identified in 2016-2017, and the sowing period, emergence period, budding period, bolting period, and main sprouting period of each combination were recorded separately, and the growth period was selected. ; Select the taste of cabbage sprouts through the combination of fresh taste in the field and fried taste; through the statistics of the root number of 20 consecutive cabbage plants in each combination, select the combination with strong regeneration ability; through disease resistance and cold resistance Investigate to understand the resistance of each combination; finally count the actual harvest yield of commercial sedges for each combination. Based on the above selections, the hybrid combination of 118A and the new line 927 has the advantages of early development, crisp and sweet taste, good disease resistanc...

Abstract

The invention belongs to the technical field of crop breeding, and particularly relates to a breeding method of a novel rape variety oil moss 929 for early-maturing high-yield flowering Chinese cabbage. According to the method, a cytoplasmic male sterile line 118A is selected as a female parent, a self-selected restoring line 927 which is crisp and sweet in taste, early in development and high in resistance is selected as a male parent for hybridization, an F1 generation is obtained and subjected to combined identification, and a combination 118A * 927 which has the characteristics of being early in development, crisp and sweet in taste, good in lodging resistance, disease resistance and cold resistance and high in flowering Chinese cabbage yield, namely the oil moss 929 of the variety is obtained. The oilseed rape 929 bred through the breeding method breaks through the single oil function of traditional oilseed rape, the vegetable function of the oilseed rape is expanded, the fructose content is high, the taste is crisp and sweet, the prematurity is good, compared with the oilseed rape Zhongshuan No.11, the flowering Chinese cabbage appears on the market 80-90 days earlier, the yield of the flowering Chinese cabbage per mu is increased by 700-800 kg, the blank of the flowering Chinese cabbage before the spring festival of Hunan is filled up, and the flowering Chinese cabbage 929 is worthy of popularization and application. The rape planting benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, and in particular relates to a breeding method for a new early-maturing and high-yielding rapeseed variety Youtai 929. Background technique [0002] Traditional rapeseed cultivation is mainly based on harvesting rapeseed and pressing oil. The output value per mu is about 600-750 yuan. After removing the production cost, the net profit per mu is about 100-250 yuan. The low planting efficiency has seriously affected the development of rapeseed. In order to improve the benefit of rapeseed planting, in recent years, more and more attention has been paid to the multifunctional development of rapeseed for vegetable, fertilizer, feed, ornamental and honey. Rapeseed sprouts are emerald green in color, rich in vegetable flavor, and contain a variety of vitamins and trace elements that are beneficial to human health. It is a new type of sprout vegetable. However, the rapeseed sprouts currently on th...
