Embodiment 1

[0044] The present embodiment provides the breeding method of Brassica napus variety Ganyou 105, comprising the following steps:

[0045] 1. Combined Configuration and Field Trials

[0046]In 2007, spring and semi-winter Brassica napus breeding resources from different sources were selected, and there were 10 spring Brassica napus varieties, namely Dunkeld, Monty, Bronowski ( Bronowski), Defender, Altex, Global, Green Oil No. 14, Sponsor, Comet, Surpass440, Semiwinter There are 16 varieties of Brassica napus, namely Gui 416, Qianyou 23, Qianyou No. 9, Yuyou No. 2, Zhongyou 821, Glycerin No. 5, Xiangyou No. 13, Ganyou No. 12, Xiuyou No. 1, Qinyou No. No. 1, Huyou No. 18, Shengli Qinggeng, Chuanyou No. 1, Yiyou No. 13, Zheshuang No. 6, and Zheyou No. 3. In May 2007, it was planted in a test field in Xining City, Qinghai Province according to conventional cultivation techniques. Each variety was sown in 2 rows, and each row had 15 seedlings. When flowering in July 2007, the spr...

Embodiment 2

[0057] The present embodiment provides the breeding method of Brassica napus variety Ganyou 526, comprising the following steps:

[0058] 1. Combined Configuration and Field Trials

[0059] In 2013, spring and semi-winter Brassica napus breeding resources with excellent comprehensive traits were selected. There were 10 spring Brassica napus varieties, namely DHQ2, DHQ4, DHQ5, DHQ7, DHQ10, Global, Qingyou 14, Buri Bullet, Erra, Rioklas, and 17 semi-winter rapeseed varieties, namely Zhongshuang 9, Zhongshuang 11, Zheyou 28, Sunshine 2009, Huyou 15. Huyou 18, 283B, Xiangyou No. 15, Ganyou No. 18, R210, Huyou 21, Ganyou 105, Zhejiang Youyou 5002, Sunshine 2008, DH730, SY116, 9818, among them, the DHQ used in this example The series of germplasm resources come from the Crop Research Institute of Jiangxi Academy of Agricultural Sciences. In May 2013, it was planted in the experimental field in Xining City, Qinghai Province, according to conventional cultivation techniques. Each va...

Abstract

The invention belongs to the technical field of crop breeding, and specifically relates to a breeding method for an early-maturing brassica napus variety. The breeding method comprises three steps ofcombination configuration and field test, parent dominant group screening and parent dominant group offspring identification. The breeding method for the early-maturing brassica napus variety on the basis of the parent dominant group is provided for the first time; excellent comprehensive characters of a semi-winter brassica napus dominant group variety are introduced into a spring brassica napusdominant group variety with early maturity by combining analysis of the general combining ability of parents and the special combining ability of hybridized combinations; thus, excellent comprehensivecharacters and early maturity can be better combined; the early-maturing brassica napus variety can be screened and identified more easily; the breeding efficiency is improved; the uncertainty of variety screening in the prior art is avoided; meanwhile, the method provided by the invention is easy to implement and low in cost.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, and in particular relates to a breeding method for early-maturing Brassica napus varieties. Background technique [0002] Rapeseed is an important oil crop in my country. There are three types of rapeseed cultivated in China: brassica oleracea, Chinese cabbage-type rape and mustard-type rape. Brassica oleracea belongs to the family Cruciferae (Cruciferae) Brassica (Brassica). It is the second largest bulk oil crop in the world. It is the main source of edible vegetable oil and an important oil crop that provides biodiesel and other industrial raw materials. [0003] my country consumes a large amount of vegetable edible oil every year, and rapeseed has become the most important oil crop to ensure the safety of vegetable edible oil supply in China; winter rapeseed in the Yangtze River Basin does not compete with rice, corn and other summer grain crops, and the production area of ​​early-matu...
