Abstract
The present invention relates to ear riched hybrid sorghum parent and new combination breed selection, propagation and breeding method. It is characterized by that pedigree method is adopted in hybrid sorghum male sterile line breed selection, bagging self-cross is adopted in cultivated head progeny row pedigree in breed selection of male maintenance line, bagging self-cross is adopted in cultivated plant pedigree also, the selected maintenance line and sorghum sterile line are hybridized, then the backcross method is adopted to transform sterile line, etc. The new variety of hybrid sorghum breed-selected by said method possesses the advantages of saving water, resisting drought, high yield and good quality.
Description
The present invention relates to a kind of seed selection, breeding, producing method for seed of hybrid sorghum.
Jowar has very strong drought resistance and resistance to overhead flooding injury.Before the liberation, China's jowar kind is grown area and is only second to paddy rice, wheat, occupies the 3rd.After liberation, rice breeding, corn breeding techniques raising along with China, the amount of increase in production of paddy rice and corn is big, it is increasing to make the kind of paddy rice and corn grow area, conventional in addition jowar yields poorly, poor quality, factors such as tannin content height make the pretty right disappearance in a lot of provinces of China of this ancient traditional crop of jowar, nobody shows any interest in.Because paddy rice and corn large tracts of land are promoted, and make the province lack of water of the original water resource deficiency of China seem more obvious, suffer from drought every year.Particularly Yangze river and Huai river watershed area lack of water phenomenon is more outstanding, and drought had become rule in 5 years three, and drought has perplexed cadres and masses' work of this area, causes farmers' income low, rural economy difficulty, slower development.China will join WTO after 2000, and agricultural production need constantly be transformed agricultural production along with market economic development changes.Seed selection high-quality hybrid sorghum variety develops water-saving agriculture for this reason, industry restructuring, and the extension industry chain has crucial meaning.
The objective of the invention is to: a kind of breeding time weak point, water saving, drought-enduring, high yield, parent of fine quality and seed selection, breeding, the producing method for seed of new combined hybrid jowar are provided.
The technical solution that realizes above-mentioned purpose is such.
Seed selection, breeding, the producing method for seed of ear riched hybridized Chinese sorghum parent and new combination, the pedigree method seed selection is adopted in its seed selection, it is characterized in that:
The seed selection of hybrid sorghum
(1), the seed selection of hybrid sorghum male sterile line
(1.1), the seed selection of male maintenance line
Utilize the hybrid sorghum breeding material, the concrete steps of screening hybrid sorghum male sterility maintainer line are as follows:
(1.1.1), select the single fringe of good jowar;
(1.1.2), plantation head progeny row spectrum: selected plant blade profile attitude unanimity, breeding time is identical, flowering habit is good, the head progeny row that pollen amount is big, and bagging selfing in selected head progeny row are selected single fringe, eliminate the inconsistent head progeny row of proterties;
(1.1.3), plant the plant pedigree: above-mentioned single fringe of obtaining is used for plantation, and enlarges plantation colony, select the good strain system of typical proterties, continue the bagging selfing, the menu fringe is eliminated the inconsistent strain of proterties system, with its material as the transformation male sterile line;
(1.2), the seed selection of male sterile line
The method transformation male sterile line of backcrossing is adopted in jowar breeding material that the above-mentioned male sterile confining force of obtaining is high and the hybridization of jowar male sterile line again, and its concrete operations step is as follows:
Jowar male sterile line * jowar individual plant

Breeding male sterile lines
(2), the hybrid sorghum male sterile line recovers the seed selection and the combo of system
From the jowar breeding material, select comprehensive proterties good and have a strain of restoring force, hybridize with the jowar male sterile line that above-mentioned seed selection obtains, obtain the F1 seed, with F1 seed and male parent and other hybrid sorghum plantation same period that obtains, observe breeding time, growth potential, resistance and the heterosis, hybrid vigor of F1 and male parent and other jowar,, select the hybrid sorghum of high yield, high-quality, resistance newly to make up by indoor species test and quality testing.
The breeding of hybrid sorghum male sterile line
(1), sowing time: in Anhui early April sowing, the late June heading is sowed to earing about 75 days; The early June sowing, the early August heading, sowing is to earing about 60 days;
(2), father and mother's one's own profession ratio: hybrid sorghum sterile line propagation father and mother one's own profession ratio is 2: 3 or 2: 4;
(3), seeding row spacing: be 20cm * 50cm, around the hybrid sorghum breeding field in 300 meters scopes, the jowar with the breeding male sterile lines heading same period, flowering can not be arranged, in case influence male sterile line purity;
(4), pollination: adopt artificial pollination, adopt powder morning, pollen is collected in the paper web, when female parent is bloomed, pollinate with springing paper web and gentle breeze adopting the paternal pollen that comes, it is solid that female parent is pollinated;
(5), results: receive male parent earlier during the seed maturity of breeding field, receive maternal again; During results, list is received, is singly taken off, dries, and the packing warehouse-in is in case mix.
The production of hybrid seeds of hybrid sorghum
(1), sowing time: the sowing of Anhui production of hybrid seeds early April to early June all can, father and mother sow this same period:
(2), the strict isolation: the jowar that the heading same period, flowering can not be arranged with the seed farm male sterile line in 300 meters scopes around the hybrid sorghum seed farm;
(3), father and mother's one's own profession ratio: 2: 3 or 2: 4;
(4), seeding row spacing: 20cm * 45cm or 20cm * 50cm;
(5), pollination: adopt artificial pollination, adopt powder morning, pollen is collected in the paper web, when female parent is bloomed, pollinate with springing paper web and gentle breeze adopting the paternal pollen that comes, it is solid that female parent is pollinated;
(6), results: receive male parent during the seed farm seed maturity earlier, receive maternal again; During results, list is received, is singly taken off, dries, and the packing warehouse-in is in case mix.
The present invention has the advantage of several respects:
One, method of the present invention row easy and simple to handle, easy is applicable to China each province.
Two, the new combined hybrid jowar of adopting this method to cultivate has following many-sided advantage:
1, breeding time is short: hybrid sorghum, all can be planted in China each province about the 100 days time of infertility in Anhui sowing mid-June.
2, water saving is drought-enduring: hybrid sorghum and sowing hybrid maize same period, only fall under the situation of 35mm rainwater emerging to heading, and the corn total crop failure, and the hybrid sorghum normal growth, ear, blossom and bear fruit, shown that the hybrid sorghum drought resistance is strong.
3, output height: several about 4000 of the real grain of hybrid sorghum list fringe, thousand kernel weight 33 grams, single fringe weighs about 125 grams, calculates with every mu of kind 6000 caves, and per unit area yield can reach about 750 kilograms.
4, product are of fine quality: the hybrid sorghum seed is white endosperm, tannin content about 3%, and content of starch is about 66%, amino acid content height, cane sugar content height.
5, the hybrid sorghum seed can be made liquor-making raw material, improves the mouth matter of wine.With its cane ammoniumization, development sheep raising, cowboying can promote animal husbandry development.
