Description

The selection of a kind of black barley

One, technical field

The present invention relates to the selection of a kind of black barley, belong to the 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, people are more and more diversified to the demand of food, and the big wheat food of black is in great demand on market in recent years very much, and price is 2 times of yellow big wheat food.But the kind of the black barley of using in the production is " ratio difficult to understand ", and its plant height is too high, and is not resistant to lodging, and output is lower, so by the anti-barley of the falling black new varieties of breeding high-yield, can satisfy the demand of people to the big wheat food of black.

Three, summary of the invention

1, technical problem

It is not high to The present invention be directed to domestic black barley production, a kind of black barley breeding method that the problem that lodging resistance is not strong proposes, and the black barley variety of being bred is the output height not only, and lodging resistance is strong, and seed is big, suitable processing.

2, technical scheme

Black barley breeding method provided by the present invention comprises:

Spending 30 to be female parent with two-rowed barley, is male parent with black barley new lines 96717, and the artificial hybridization combo is female parent with F1 for plant, is the samsara male parent to spend 30, repeatedly backcrosses, and notes selecting the black individual plant in backcross process, obtains black barley crossbreed.

Because barley black proterties is to be controlled by single-gene, black is dominance, when the first generation of hybrid of yellow barley and black barley is ripe, seed is a black, its offspring has separating of yellow plant and black plant, is that female parent is done hybridization with hybrid generation, does the samsara male parent with yellow barley malt 30, in doing crossover process, when castrating, plant all is dark green, can not divide yellow plant and black plant, so each plant is only cooked 1 fringe when castrating, to do some tassels more, generally do 10 more than the tassel, can guarantee to gather in the crops and be no less than 3 black barleys hybridization tassels, when seed is ripe, can tell black plant and yellow plant.During results, only receive the crossbreed of black seed, abandon the crossbreed of yellow seed.

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

A plurality of black barley strains system is selected for selfing through 1-2, can cultivate into plant height 80-90cm, anti-ly falls, 15 to 22 of number of grain per ears, the black barley new varieties more than thousand kernel weight 42 grams.

3, beneficial effect

The present invention adopts the method for backcrossing to cultivate black barley new varieties, and it is fast to have speed, and easy selection etc. are effect actively.

1. the method for backcrossing breeding, economical character is stable fast, and quick breeding becomes new varieties easily.

2. because barley black proterties is that black is dominance by single-gene control, and yellow is recessive, and when the first generation of hybrid of yellow barley and black barley was ripe, seed was a black, when generation, separated the back, the black proterties was reproduced easily, is difficult for losing.

3. spend 30 to be high yielding variety of short stem, that fringe is many, fringe is little, grain is big.To spend 30 to be that the parent backcrosses, breed economical character and spend 30 close black barley new varieties, because black barley new varieties tassel granule is big, the photosynthetic product that institute's linear leaf produces is transported in the seed aborning, forms big grain easily.The black barley of big grain is convenient to processing, is received by the market.Characteristics such as that improved line has is of short stem, anti-ly fall, output height, thousand kernel weight height, wide adaptability.In the performance of jiangsu coast area better, its thousand kernel weight is fit to the demand of processing Mai Ren, oatmeal up to more than the 42g, is about at coastal area, Jiangsu Province popularizing planting.
