Description
Technical field
The invention belongs to the selection of New Crop Varieties, be specifically related to a kind of selection of chrysanthemum New Glutinous Rice Variety.
Background technology
Paddy rice is rice seed in grass family, and Chinese sorghum is Chinese sorghum kind in grass family, belongs to equal not of the same race between them.Paddy rice is the low-carbon (LC) plant in grass family, and Chinese sorghum belongs to grass family medium high carbon plant.Paddy rice is wet crop, and both non-refractory, not low temperature resistant again; Chinese sorghum is dry crop, the both high temperature of resistance to 40～50 ℃, low temperature that again can cold-resistant resistance to 13 ℃.Paddy rice is to have photorespiration, and organic matter accumulation is not high; Chinese sorghum is without photorespiration, and organic matter accumulation is high.Paddy rice takes root shallow in soil, and stem stalk is thin, a little less than lodging tolerance; And Chinese sorghum takes root deeply in soil, stem stalk is sturdy, and lodging tolerance is strong.From flowering time, both also have difference.The Rice Flowering time generally from the morning 8 up at 2 o'clock in afternoon, can not resist the harm of high low temperature; And the flowering time of Chinese sorghum generally from the morning 5 up at 10 o'clock in the morning, and can just carry out self-control with temperature, when temperature is higher than 30 ℃, just bloom 5 o'clock mornings, temperature is in the time of 15 ℃, at 10 o'clock in the morning just bloomed.Paddy rice and Chinese sorghum chasmogamy rate have height not: the pollen of paddy rice male flower is 90% to the fertilization rate of female flower, and the pollen of Chinese sorghum male flower is 100% to the fertilization rate of female flower.The rice of paddy rice belongs to cold food, and sorghum rice is warm nature food.As can be seen here, the character of paddy rice and Chinese sorghum is completely contradicted, if by paddy rice and Sorghum Hybrid success, can be in harmonious proportion mutually, and the proterties that not only can be in harmonious proportion separately, and can improve a meter matter, improve edibility.
Yet because paddy rice and Sorghum Hybrid belong to plant edge sexual hybridization far away, difficulty is very big, is difficult for successfully.
Summary of the invention
The problem existing for prior art, the object of the invention is to the technical scheme that design provides a kind of selection of chrysanthemum New Glutinous Rice Variety.
The selection of described a kind of chrysanthemum New Glutinous Rice Variety, is characterized in that comprising the following steps:
1) accurately selecting sorghum variety ring carving glutinous is male parent, and the black Xian of rice varieties is glutinous is maternal, wears sowing planting, carries out distant hybridization between section, obtains F1 generation, then plants into F2 generation;
2) from F2 generation, screening plant height is that the plant of 80～100cm is planted into F3 generation, then from F3, to screen plant height generation be that the plant of 90～100cm is planted into F4 generation;
3) from F4 generation, screening plant height is that the plant of 90～100cm is planted into F5 generation, F5 is for the plantation that continues to go down to posterity, screening, until obtain plant height, be stabilized in 90～100cm, ripening rate is higher than more than 85%, thousand kernel weight is 25～28g, sterile lemma is with Chinese sorghum shape, and peeling grain of rice kind skin is red waxy plant, obtains chrysanthemum New Glutinous Rice Variety.
The selection of described a kind of chrysanthemum New Glutinous Rice Variety, it is characterized in that by Chinese sorghum and paddy rice florescence, observing in described step 1), determine both pollination times, and determine both sowing time separately, both florescences are coincide, cut off maternal 1/3 clever shell simultaneously, birchleaf viburnum root powder is descended slowly and lightly naturally and on paddy rice pistil column cap, carry out spontaneous pollination.
The present invention is glutinous and glutinous distant hybridization and the continuous multi-generation seed selection kind of carrying out of the black Xian of rice varieties by sorghum variety ring carving, obtain new varieties chrysanthemum glutinous rice, according to relevant mensuration, in this chrysanthemum glutinous rice, be rich in microelements of calcium, magnesium, iron, zinc and the selenium of needed by human body, wherein the content of calcium, magnesium, iron and zinc is higher more than 14 times than general rice content, the content of selenium is higher more than 2 times than general rice content, and output is than other red glutinous rice volume increase 20-30%, and per mu yield can reach 600 kilograms of left and right.
The key point that the present invention can cultivate chrysanthemum New Glutinous Rice Variety is:
1, selecting properly sorghum variety: the Chinese sorghum of selection must be stablized by hereditary factor, and morphological feature is good, and the kind that pollen grain is less and paddy rice carry out sexual hybridization, the chrysanthemum glutinous rice variety of guarantee incubation is excellent like this, output is high.The present invention selects Fuyang Chinese sorghum ring carving glutinous, and its pollen grain is thinner than existing birchleaf viburnum root powder, and its morphological feature is better, has stable hereditary factor, and this kind has had the plantation of centuries historical in area, Fuyang.
2, selecting properly rice varieties: the rice varieties of selection must be stablized by hereditary factor, and morphological feature is good, and ovule is larger.The glutinous pistil stigma of the black Xian of paddy rice that the present invention selects expose and ovule larger, it has now planted number generation, morphological feature is consistent, and has stable hereditary factor.
3, adopt spontaneous pollination: by paddy rice with Chinese sorghum blooms separately and definite sowing time separately of the reckoning of the time of pollinate, its florescence is coincide, take paddy rice as maternal, cut off 1/3 clever shell, the pollen of Chinese sorghum maturation is descended slowly and lightly naturally on paddy rice pistil stigma, carry out nature insemination.Sorghum pollen quietly completes pollination and fertilization process in the situation that constantly descends slowly and lightly and between paddy rice, has solved that artificial pollination opportunity is inaccurate and pollination frequency is limited with this, can not guarantee fertilization and be subject to extract Iuality and the unsuccessful difficult problem of breeding.In addition, fact proved, adopt spontaneous pollination of the present invention to exceed hundreds of times than the success rate of artificial pollination.So just increased the fertilization probability of parent.
