Abstract

The invention discloses a selection method of ornamental red cabbage oilseed rapes. The selection method comprises the following steps: classifying red cabbage oilseed rape seeds found in the lishui river basin in Changde, Hu'nan into three groups, one for preservation, one for selection as a male parent which is hybridized with 'No. 886-9' serving as a female parent to obtain F1, and the other one for selection as the female parent which is hybridized with 'No. 886-9' serving as a male parent to obtain F2; hybridizing F1 and F2 to obtain F3; performing selfing to obtain F4, performing quality analysis, selecting each generation according to two standards of ornamental property and high oil content for reasonable cultivation, performing selfing for 5 generations, and selecting to obtain a new type of the ornamental type red cabbage oilseed rapes. The new type has the two characteristics of 1, large petal size, red color, long flowering period, a large number of flowers, plant height greater than 150 cm and pest damage resistance; 2, higher shattering resistance; more than 150 kg of rapeseeds are produced per mu; the oil content of the rapeseeds is 39 percent, the cake sulfur glucoside content is less than 17 [mu]mol/g, the erucic acid content is 0, the oleic acid content is 43 percent, and the linolenic acid content is 10 percent.

Description

A kind of selection of sightseeing type safflower cabbage type rape

Technical field

The present invention relates to the seed selection of rape variety, the selection of a kind of sightseeing type safflower cabbage type rape.

Background technology

Rape, is again pakchoi, bitter dish, Latin literary fame: Brassica campestris L. Cruciferae, brassica plant, originates in China, and its stem color is dark green, and flower is yellow.Rape Main Cultivation (kind) type is at present: turnip type rape (Brassica rapa (campestris) L.), mustard type rape (Brassica juncea L.) and cabbage type rape (Brassica napus L.).

Rape is mainly distributed on the ground such as Anhui, Henan, Sichuan, Hunan.Rape is nutritious, and wherein Vitamin C content is the highest.Rape is typically grown in the place that weather moistens relatively, mainly the south of China.The main use of rape is to use rapeseed oil；Rise and development along with travel industry, it is found that rape is possible not only to rapeseed oil, also find that in spring, the flavous rape flower of large area is one beautiful scenery, Hunan Province just has multi-disc rape flower to view and admire tourist district, has attracted the visitor of many to go to sightseeing tour when rape flower blooms.But at present, rape flower color is single, petal is little, the florescence is short, meets wind and the most easily lodges, and 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 having the rape of sightseeing type flower class crop, the present invention proposes the selection of a kind of sightseeing type safflower cabbage type rape.

The selection of this sightseeing type safflower cabbage type rape, it is characterized in that, the strain safflower cabbage type rape seed that changde, hunan province city Lishui River Basin finds is divided into three parts, a retention, male parent is done in second part of seed selection, " No. 886-9 " does hybridization of female parent, obtains F1；Female parent is done in 3rd part of seed selection, " No. 886-9 " does paternal hybrid, obtains F2；F1 and F2 hybridization obtains F3；Then selfing obtains F4, carries out attributional analysis, and per generation selects according to viewing and admiring two standards oily with height, rationally cultivates, after selfing 5 generation, selects to obtain sightseeing type safflower cabbage type rape new varieties.

" No. 886-9 " is Linli County, changde, hunan province city villager Shen Kequan, Shen Chang was good for father and son in 1978, the 3 strain florescences found from Guizhou mountainous area are long, the Wild Rape that growth structure is good, improve the rapeseed breeding material that the yield cultivated is high, for this Shen Kequan, Shen Chang is good for father and son and obtains the title of honour of 2014 touching service ten VIPs, the feature of " No. 886-9 " material is up to more than 15, the branch of plant mobile jib, resistant to lodging, premature senescence resistance, more than plant height 160cm, per mu yield rapeseed is up to 155kg, rapeseed oil content 40.5%, below grouts glucosinolate content 16 μm ol/g, content of erucic acid is 0, oleic acid content is 44%, linolenic acid content is 10.5%.Shen Changjian now stays in Yang Qiao village, "four news" (new ideas hilllock town, Linli County, changde, hunan province city Wu Xi group, postcode 415207, and for the peasant household of breeding of making scientific researches, " No. 886-9 " material is available at any time should.

Described selection standard: 1, pattern is redness, petal is big, florescence length, flower number are many, plant height more than 150 centimetres, and once effective branch more than 10, without pest and disease damage, do not lodge；2, shattering resistance is preferable, and every per mu yield rapeseed more than 150 kilograms, rapeseed oil content 39%, below grouts glucosinolate content 17 μm ol/g, content of erucic acid is 0, and oleic acid content is 43%, and linolenic acid content is 10%.

Described reasonable cultivation: 1. early sowing in good time: nursery Suitable Sowing Period in lower Yangtze area 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, culturing and transplanting seedlings rational density is 0.8-1.1 ten thousand plants/acre, during fertility higher level, density 0.8-0.9 ten thousand plants/acre, during fertility reduced levels, density 1.0-1.1 ten thousand plants/acre；3. apply fertilizers scientifically: heavy base fertilizer application, mu sealing fertilizer 50 kilograms；Imposing seed manure, when 5-8 sheet true leaf, mu executes 10-15 kilogram of urea；Must execute boron fertilizer, bottom application borax every mu 1-1.5 kilogram, tongue phase spraying concentration is the borax soln of 0.2%；4. controlling disease: in grave illness district attention control sclerotiniose, spraying dimethachlon, dimethachlon consumption and concentration in initial bloom stage one week after is that every mu of 100g dimethachlon is watered 50 kilograms.

The sightseeing type safflower cabbage type rape new varieties of the present invention have following two features: 1, petal is big, and red, the florescence is long, and flower number is many；2, every per mu yield rapeseed more than 150 kilograms, rapeseed oil content 39%, below grouts glucosinolate content 17 μm ol/g, content of erucic acid is 0, and oleic acid content is 43%, and linolenic acid content is 10%.
