Abstract
The invention discloses a breeding method of sightseeing white flower brassica napus. The breeding method comprises the following steps: dividing white flower brassica napus seeds which are discovered from the lishui river basin, Changde City, Hunan Province into three parts, preserving one part, breeding the second part as a male parent, and hybridizing 'zhongshuang No. 11' as a female parent with the male parent to obtain F1; breeding the third part as the female parent, and hybridizing the 'zhongshuang No. 11' as a male parent with the female parent to obtain F2; hybridizing F1 and F2 to obtain F3; then performing selfing to obtain F4, carrying out quality analysis, selecting each generation according to two standards of sightseeing and high oil, and carrying out reasonable cultivation; and performing selfing for five generations, and selecting and obtaining the new variety of the sightseeing white flower brassica napus. The new variety disclosed by the invention has two characteristics that 1 the sightseeing white flower brassica napus is large in petal, white, long in flowering phase and large in flower number; the plant height is greater than 150cm; and plant diseases and insect pests can be resisted; 2 the shattering resistance is relatively good; over 150kg of rapeseeds can be produced per mu; the oil content of the rapeseeds is 39%; the glucosinolate content of a seed cake is less than 15mu mol/g; the erucic acid content is 0; the oleic acid content is 43%; and the linolenic acid content is 11%.
Description
Technical field
The present invention relates to the seed selection of rape variety, namely a kind of sightseeing type spends the selection of cabbage type rape in vain.
Background technology
Rape, is pakchoi again, bitter dish, Latin literary fame: BrassicacampestrisL. Cruciferae, brassica plant, and originate in China, its stem color is dark green, and flower is yellow.Current rape Main Cultivation (kind) type is: turnip type rape (Brassicarapa (campestris) L.), mustard type rape (BrassicajunceaL.) and cabbage type rape (BrassicanapusL.).
Rape is mainly distributed in the ground such as Anhui, Henan, Sichuan, Hunan.Rape is nutritious, and wherein Vitamin C content is very high.Rape generally grows in the relatively moistening place of weather, mainly the south of China.The main use of rape is with rapeseed oil; Along with the rise and development of travel industry, it is found that rape not only can use rapeseed oil, also find that the flavous rape flower of large area in spring is one beautiful scenery, Hunan Province just has multi-disc rape flower to view and admire tourist district, has attracted many visitors to go to sightseeing tour when rape flower blooms.But rape flower color is single at present, petal is little, the florescence is short, meets wind and also easily lodge, is a unavoidable shortcoming as sightseeing type flower class crop.
Summary of the invention
In order to seed selection one can not only be extracted oil, and there is the rape of sightseeing type flower class crop, the present invention proposes the selection that a kind of sightseeing type spends cabbage type rape in vain.
This sightseeing type spends the selection of cabbage type rape in vain, it is characterized in that, spend the strain that changde, hunan province city Lishui River Basin finds in vain cabbage type rape seed and be divided into three parts, a retention, male parent is done in second part of seed selection, " in two No. 11 " does hybridization of female parent, obtains F1; Female parent is done in 3rd part of seed selection, " in two No. 11 " does paternal hybrid, obtains F2; F1 and F2 hybridization obtains F3; Then selfing obtains F4, carries out attributional analysis, and per generation is selected with height oil two standards according to viewing and admiring, and rationally cultivates, after selfing 5 generation, selects to obtain sightseeing type and spend cabbage type rape new varieties in vain.
" in two No. 11 " is that seed selection is successful under the subsidy of national " 863 ", " 973 ", science and technology supporting project and national Rape industry technical system, have passed national region test and variety certification smoothly, overcome high oil and high yield, high oil and disease-resistant, high oil and two three low large contradictions in rapeseed breeding.This kind rape seed Average oil concentration reaches 49.04%%, and every per mu yield rape seed is up to 167.3 kilograms, its pair of low-quality excellence, and content of erucic acid has dropped to zero; In addition, this kind also has disease resistance and the strong feature of lodging resistance.But this kind only on the south Huaihe River, Jiangsu Province, on the south Huaihe River, Anhui Province, Zhejiang Province, Shanghai City winter rape main producing region popularizing planting, in Hunan plantation seldom.
Described selection criteria: 1, petal is large, white, the florescence is long, and flower number is many, plant height more than 150 centimetres, and once effective branch more than 8, without damage by disease and insect, does not lodge; 2, shattering resistance is better, and every per mu yield rape seed more than 150 kilograms, rapeseed oil content 39%, grouts glucosinolate content 15 μm of below ol/g, content of erucic acid is 0, and oleic acid content is 43%, and linolenic acid content is 11%.
Described reasonable cultivation: 1. in good time early sowing: lower Yangtze area nursery Suitable Sowing Period is in 9 months, the last ten-days period, in 10 months, the last ten-days period transplant; 2. rational close planting: under medium fertility level, seedling raising and transplanting rational density is 1.2-1.5 ten thousand plants/acre, during fertility higher level, density 1.2 ten thousand plants/acre, during fertility reduced levels, density 1.5 ten thousand plants/acre; 3. apply fertilizers scientifically: heavy base fertilizer application, mu sealing fertilizer 50 kilograms; Impose seed manure, when 5-8 sheet true leaf, mu executes urea 10-15 kilogram; Must execute boron fertilizer, bottom application borax every mu of 1-1.5 kilogram, tongue phase spraying concentration is the borax soln of 0.2%; 4. controlling disease: in grave illness district attention control stalk break, sprays dimethachlon in one week after initial bloom stage, and dimethachlon consumption and concentration are that every mu of 100g dimethachlon is watered 50 kilograms.
Sightseeing type of the present invention is spent cabbage type rape new varieties in vain and is had following two features: 1, petal is large, white, and the florescence is long, and flower number is many; 2, every per mu yield rape seed more than 150 kilograms, rapeseed oil content 39%, grouts glucosinolate content 15 μm of below ol/g, content of erucic acid is 0, and oleic acid content is 43%, and linolenic acid content is 11%.
