Description
Technical field
The present invention relates to crop breeding fields, and in particular to a kind of selection of two rib naked barleys.
Background technique
Two rowed barley is a subspecies in vulgare kind, scientific name H.vulgare ssp. distichon Hs ü.Fringe
For shape in flat, two rib barley Grain starch contents height, malt is high-quality.But the naked barley currently planted is mainly more ribs
Naked barley, low output and lodging tolerance is poor.
Summary of the invention
The purpose of the present invention is to above-mentioned defects in the prior art, provide a kind of breeding side of two rib naked barleys
Method.
To achieve the goals above, technical solution provided by the invention are as follows: a kind of selection of two rib naked barleys, including
Following steps:
1) with two--rowed malting barley Fa Wawei specially for female parent, the naked Wild Barley ZYM0981 of two rib of Tibet is male parent, and artificial hybridization is matched
Group obtains Fa Waweite × ZYM0981 Hybrid F1 ' for plant, F1 ' 2 rows of generation sowing；
It 2) is female parent, the Fa Waweite × ZYM0981 Hybrid F1 obtained with step 1) with high-quality stable barley strain 9810 '
It is male parent, artificial hybridization combo, second year sowing F1 generation kind for plant；
3) F1 generation that step 2 obtains sows 2 rows, and unified mixing harvest, air-dries and save, obtain F2 generation after mature；
4) in the F2 generation that step 3) obtains, sows 50 rows, row long 1.5m, line-spacing 0.25m, spacing in the rows 6.0cm, every row program request 26, group
Various 2 rows of standard variety in front and back are closed, field largely selects single plant, and carries out single plant harvest, air-dries and saves, obtains F3 generation；
5) the F3 generation that step 4) obtains, single plant 2 rows of sowing, row long 1.5m, line-spacing 0.25m, spacing in the rows 6.0cm, every row program request 26,
Various 2 rows of standard variety in combination front and back carry out single plant harvest after selecting single plant, air-dry and save, obtain F4 generation,
6) acquisition in F5 generation and F6 generation is the operation for repeating step 5), finally obtains F7 generation；
7) in the F7 generation that step 6) obtains, selects to stablize naked barley strain, is named as naked barley strain 0406-17.
Further, the selection of above-mentioned two rib naked barley of one kind, the artificial hybridization of the step 1) and step 2
In the process, each plant is only cooked 1 fringe when emasculation, to make 5 tassels or more, and when Grain Ripening, mixing harvest is air-dried and protected
It deposits, respectively obtains F1 ' for cenospecies and F1 generation kind.
Further, the selection of above-mentioned two rib naked barley of one kind in the step 4)-step 6), selects single plant
It is to select plant height 80cm, anti-fall, number of grain per ear 20 or more, 42 grams of mass of 1000 kernel or more, the single plant of naked grain in generation after hybridization.
The invention has the benefit that a kind of selection of two ribs naked barley provided by the invention, has speed fast, easily
The good effect of selection.In this breeding method, two rib barley Fa Waweite and the naked Wild Barley ZYM0981 of two ribs are selected first
It is assembled for parents, character is stablized fastly, is easy quick breeding into new varieties；Secondly selection is high-quality, high yield, extensively fits, coordinate force
For high barley Fa Wawei specially for female parent, improved line has the characteristics that anti-fall, yield is high, mass of 1000 kernel is high, wide adaptability；Again
Select Xizang Wild naked barley ZYM0981 for male parent, improved line can more preferably be suitable for China naked barley (highland barley) planting area.
Specific embodiment
Embodiment 1:
