Description

A kind of selection of black barley

One, technical field

The present invention relates to a kind of selection of black barley, belong to crop breeding technical field.It is exclusively used in the production of black barley.

Two, background technology

Along with the raising of people's living standard, the demand of people to food is more and more diversified, and black barley food is commercially in great demand in recent years very much, and price is 2 times of yellow large wheat food.But in production, the kind of the black barley of application is " ratio difficult to understand ", and its plant height is too high, not resistant to lodging, and output is lower, so by the anti-fall black barley new varieties of breeding high-yield, can meet the demand of people to black barley food.

Three, summary of the invention

1, technical problem

The present invention be directed to domestic black barley output not high, a kind of black barley breeding method that the problem that lodging resistance is not strong proposes, not only output is high for the black barley kind be bred as, and lodging resistance is strong, and seed is large, suitable processing.

2, technical scheme

Black barley breeding method provided by the present invention comprises:

Spend 30 for maternal with two-rowed barley, with black barley new lines 96717 for male parent, artificial hybridization combo, with F1 generation plant for female parent, to spend 30 for samsara male parent, repeatedly backcross, attentional selection black individual plant in backcross process, obtains black barley crossbreed.

Because barley black proterties is by Dominant gene, black is dominant, when the first generation of hybrid of yellow barley and black barley is ripe, seed is black, its offspring has being separated of yellow plant and black plant, be that female parent does and hybridizes with hybrid generation, samsara male parent is done with yellow barley malt 30, doing in crossover process, when emasculation, plant is all dark green, can not divide yellow plant and black plant, so each plant is only cooked 1 fringe during emasculation, some tassels will be made more, generally make more than 10 tassels, can guarantee that results are to being no less than 3 black barley hybridization tassels, when Grain Ripening, black plant and yellow plant can be told.During results, only receive the crossbreed of black seed, abandon the crossbreed of yellow seed.

Each black barley hybridization tassel plants into head progeny row separately, be used as hybridization maternal, to spend 30 for samsara male parent, backcross, the individual plant of plant height 80-90cm, anti-fall, number of grain per ear 15 to 22, thousand kernel weight more than 42 grams, black seed is selected in second time backcross progeny, only receive the plant of black seed in the selection process, abandon yellow seed plant, obtain a collection of black barley strain.

Multiple black barley strain for self cross and selection, can cultivate into the black barley new varieties of plant height 80-90cm, anti-fall, number of grain per ear 15 to 22, thousand kernel weight more than 42 grams through 1-2.

3, beneficial effect

The present invention adopts Backcrossing methods to cultivate black barley new varieties, has speed fast, and easily selection waits good effect.

1. Backcrossing methods breeding, economical character is stable fast, and easy quick breeding becomes new varieties.

2. because barley black proterties is by Dominant gene, black is dominant, and yellow is recessive, and when the first generation of hybrid of yellow barley and black barley is ripe, seed is black, and during for rear separation, black proterties is easily reproduced, and not easily loses.

3. 30 are spent to be of short stem, that fringe is many, fringe is little, grain is large high yielding variety.To spend 30 to backcross for parent, be bred as economical character and spend 30 close black barley new varieties, aborning because black barley new varieties tassel granule is large, the photosynthate translocation that institute's linear leaf produces, in seed, easily forms large grain.The black barley of large grain is convenient to processing, is received by the market.Improved line has of short stem, anti-fall, the feature such as output is high, thousand kernel weight is high, wide adaptability.In Littoral Jiangsu Province performance better, its thousand kernel weight, up to more than 42g, is applicable to the demand of processing Mai Ren, oatmeal, is about at Coastal Area of Jiangsu Province popularizing planting.
