Abstract
The present invention relates to the selection of the crisp stalk feed rice of a kind of high yield high protein, comprise the following steps: (1) by crisp stalk rice and the single cross of high yield conventional rice, reestablish diplomatic relations, breeding high-yield crisp stalk rice intermediate materials; By crisp stalk rice and the single cross of high protein conventional rice, backcross, seed selection high protein crisp stalk rice intermediate materials; (3) hybridized by high yield crisp stalk rice intermediate materials and high protein crisp stalk rice intermediate materials, breeding high-yield high protein crisp stalk feed rice new lines.Adopt the inventive method, current forage rice kind protein content can be solved not enough, the problem that Conversion of Energy availability is low.
Description
Technical field
The present invention relates to the selection of the crisp stalk feed rice of a kind of high yield high protein, specifically illustrate by single cross, reestablish diplomatic relations, the breeding method of the crisp stalk feed rice of backcross breeding high yield high protein.
Background technology
The purposes of rice has a variety of, both edibles, also can be feeding.The leading indicator of edible rice is that output is high, product are of fine quality, food flavor is good; And forage rice is careless about exterior quality, except pursuing Super-high-yielding, another one important indicator has high protein content exactly.Therefore, the rice varieties selecting high yield high protein content is the main direction of studying of current forage rice.But the protein content of conventional rice is 8% ~ 10% at present, is difficult to satisfy the demand.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to be hybridized by existing crisp stalk rice resource and high yield high protein conventional rice, there is provided the breeding method of the crisp stalk feed rice of a kind of high yield high protein, it is not enough that it can solve current forage rice kind protein content, the problem that Conversion of Energy availability is low.
In order to realize technical purpose of the present invention, the technical solution adopted in the present invention is: the selection of the crisp stalk feed rice of a kind of high yield high protein, the method comprises the steps:
By crisp stalk rice and the single cross of high yield conventional rice, reestablish diplomatic relations, breeding high-yield crisp stalk rice intermediate materials.
By crisp stalk rice and the single cross of high protein conventional rice, backcross, seed selection high protein crisp stalk rice intermediate materials.
(3) hybridized by high yield crisp stalk rice intermediate materials and high protein crisp stalk rice intermediate materials, breeding high-yield high protein crisp stalk feed rice new lines.
Compared with prior art, the crisp stalk feed rice that the present invention selects has following beneficial effect:
(1), by the hybridization with high yield high protein conventional rice, the crisp stalk feed rice selected has the characteristic of high yield high protein, solves the problem of the current feed shortage of China.The protein content of the crisp stalk feed rice new lines obtained after seed selection will apparently higher than conventional rice.
(2), by field observation, find that crisp stalk feed rice stem stalk mechanical strength is firmly crisp, plant height comparatively conventional rice is low, and lodging resistance is better than conventional rice.
(3) crisp stalk feed rice adopts crisp stalk mutant, it is the sudden change that a kind of Culm of Rice fragility increases, this sudden change decreases the crude fiber content in paddy rice, the energy that livestock and poultry decomposition raw fiber consumes can be reduced, greatly can improve the Conversion of Energy availability of nutrient component, crisp stalk feed rice Conversion of Energy availability reaches more than 65%, and common straw feed Conversion of Energy availability is 40%).
(4) crisp stalk feed rice straw is tender and crisp, and the feeding mouthfeel of livestock is good, can directly eat, and when can solve rice harves, the problem of stalk process difficulty, can stop the phenomenon of crop straw burning, can preserve the ecological environment.
Accompanying drawing explanation
Fig. 1 is breeding procedures figure of the present invention.
Embodiment
Material source of the present invention:
Crisp stalk rice material: crisp stalk mutant, can introduce a fine variety from R&D institution, science universities and colleges, as the Chinese Academy of Sciences, academy of agricultural sciences of Jiangsu Province, Agricultural University Of Nanjing, Agricultural College Affiliated to Yangzhou Univ., these materials are opener.
High protein paddy rice intermediate materials: combination (the Japanese rice of town rice 9424/), from generation to generation F
6, protein content 15.8%; Refer to town rice 9424 to hybridize with Japanese rice, then seed selection from generation to generation F6 as high protein paddy rice intermediate materials.
High yield conventional rice: town rice No. 11, even No. 7, round-grained rice.
Breeding method of the present invention is further illustrated below in conjunction with Fig. 1:
(1) obtain 25, seed by crisp stalk mutant and rice No. 11 single crosses of high yield conventional rice town, next year numbering K869 kind is planted, crisp stalk mutant and high yield conventional rice connect round-grained rice No. 7 single crosses and obtain 12, seed, next year numbering K892 kind is planted, crisp stalk mutant and the single cross of high protein paddy rice intermediate materials obtain 56, seed, and next year numbering K902 kind is planted.
(2) take K869 as female parent, K892 is paternal hybrid, obtains 256, seed, and next year numbering L1011 kind is planted; Take K902 as female parent, high protein paddy rice intermediate materials (the Japanese rice of town rice 9424/) is for male parent backcrosses, and obtain 323, seed, next year numbering L1082 kind is planted.
(3) L1011 continues additive selection high yield crisp stalk rice offspring, next year numbering L496; L1082 continues additive selection high protein crisp stalk rice offspring, next year numbering L526.
(4) be female parent with L496, L526 is that paternal hybrid obtains F
1(next year numbering L1033).Next year, field planting L1033, the young fringe getting sword-like leave pulvinus distance 2-5cm in booting stage carries out anther culture, the method of described flower training is: get booting stage sword-like leave pillow apart from 2-5cm young fringe → low temperature 4 DEG C of pretreatment 7-10 day → 6% liquor natrii hypochloritis sterilize 5 minutes → be seeded on inducing culture, to be transferred on differentiation (regeneration) medium process after 21-35 day 15 → to move on to (green seedling) medium of taking root → be transplanted to land for growing field crops → selection fine individual plant.Namely obtain 1556 parts of bloom control, therefrom seed selection is to 2 high yield high protein crisp stalk feed rice ZC-1, ZC-2; Wherein the protein content of ZC-1 is 16.2%, per mu yield 638 kilograms; The protein content of ZC-2 is 15.8%, per mu yield 646 kilograms.High-yield rice town rice No. 11 is 635 kilograms, company's No. 7, round-grained rice is 629 kilograms.
