Abstract
The invention discloses a method of cultivating nutrition and health care type red corn coenospecies. The method of the cultivating nutrition and health care type red corn coenospecies includes the following steps that 1) natural ear seed grains are all red corn selfing line msf 232 red are found in the yellow corn selfing line msf 232 breeding field. 2) The msf 232 red of the step 1) is arranged as a female parent. The yellow corn selfing line of Reid blood resources is arranged as transmigration male parent hybridization. The nutrition and health care type red corn coenospecies are hybridized in a returning mode and the nutrition and health care type red corn coenospecies are selfing hybridized. The red corns, namely Reid blood resources red selfing lines are selected from selfing hybridization progeny. 3) The msf 232 red of the step 1) is arranged as a female parent, yellow corns selfing line of non- Reid blood resources is arranged as the transmnigration male parent hybridization, returning hybridization and selfing again. The red namely non- Reid blood resources red selfing line is selected from the selfing hybridization progeny. 4) The red selfing line in the step 2) is arranged as a female parent. The red selfing line in the step 3) is arranged as a male parent. The red selfing line in the step 2) and the red selfing line in the step 3) are prepared and combined with hybridization, thus the red corn coenospecies of high combining ability are sifted.
Description
A kind of method of cultivating the red corn hybrid seed of health-care nutritive
The invention discloses a kind of method of cultivating the red corn hybrid seed of health-care nutritive.The natural mutation that the corn inbred line msf232 that is characterized in 200 meters north of a road, Luo Ji grain distribution station, Li Cang town, Mengcheng County, Anhui west (this inbred line belong to auspicious moral blood source) breeding Tanaka finds an i.e. tassel seed be all the corn of redness.Find that some is red November when Hainan adding generation (through the bagging selfing) results then, some is yellow.The reservation of redness, yellow is whole superseded immediately.Add 6 generations of generation (passing through the bagging selfing) through continuous 3 years Hainan and this locality, red corn inbred line does not just separate, and has namely cultivated red stable corn inbred line, with name for msf232 red.
Red with red corn inbred line msf232 is maternal, make the samsara male parent with the arbitrary yellow corn inbred line with auspicious moral blood source, 5 generations of continuous backcross, each all select tree characteristics to tend to the samsara male parent from the colony of backcross progeny and seed is red corn, and then continuous 5 generations of selfing, select red corn inbred line from the offspring of selfing, yellow eliminates.Namely select the red corn inbred line with auspicious moral blood source.
Red with red corn inbred line msf232 is maternal, arbitrary yellow corn selfing with Fei Ruide blood source is samsara paternal hybrid and continuous backcross, namely when the recurrent parent selfing is reserved seed for planting, get the individual plant that in its pollen and backcross progeny, the complete red tree characteristics of seed is tended to recurrent parent and backcross.Through backcrossing for 5 generations, select the last time individual plant that the complete red tree characteristics of seed is analogous to recurrent parent 5 generations of selfing again in backcross progeny, select the inbred line of good seed redness in the offspring of selfing, isolated yellow seed inbred line is all eliminated, and namely cultivates the red corn inbred line with Fei Ruide blood source.
Take the red corn inbred line that contains auspicious moral blood source as maternal, take the red corn inbred line that contains Fei Ruide blood source as male parent, preparing hybrid makes up, and therefrom filters out the red corn hybrid seed of high-combining ability, plants its offspring's seed of red corn hybrid seed and remains red.
In production, the corn hybrid seed major part of plantation is all yellow, and red corn hybrid seed is extremely rare, and red corn contains the multiple trace element useful to human body, and is anti-oxidant, anti-aging.Red corn is of high nutritive value with it, and listed price is high wins victory, and the blank of the red corn hybrid seed of China has been filled up in the seed selection of the red corn hybrid seed of health-care nutritive and utilization, occupies leading domestic status.
Claims (4)
- A kind of method of cultivating the red corn inbred line of health-care nutritive.A kind of method of cultivating the red corn inbred line of health-care nutritive comprises the following steps:1. find that yellow corn inbred line msf232 breeding Tanaka a tassel seed of natural sudden change is all red corn.Then namely the red corn seed of a fringe of natural sudden change at Hainan adding generation, during results, through the bagging selfing, some is red, some is yellow, red reservation, yellow superseded.Add 6 generations of generation through Hainan and this locality, red corn inbred line does not just separate, and namely cultivates red corn inbred line, name into msf232 red.
- 2. red with red corn inbred line msf232 is maternal, make the samsara male parent with the arbitrary yellow corn inbred line with auspicious moral blood source, 5 generations of continuous backcross, each all select tree characteristics to tend to the samsara male parent from the colony of backcross progeny and seed is red corn, and then continuous 5 generations of selfing, select red corn inbred line from the offspring of selfing, yellow eliminates.Namely select the red corn inbred line with auspicious moral blood source.
- 3. red with red corn inbred line msf232 is maternal, arbitrary yellow corn selfing with Fei Ruide blood source is samsara paternal hybrid and continuous backcross, namely when the recurrent parent selfing is reserved seed for planting, get the individual plant that in its pollen and backcross progeny, the complete red tree characteristics of seed is tended to recurrent parent and backcross.Through backcrossing for 5 generations.The individual plant of selecting the complete red tree characteristics of seed to be analogous to recurrent parent in backcross progeny the last time backcrosses.Through backcrossing for 5 generations.Select the last time individual plant that the complete red tree characteristics of seed is analogous to recurrent parent 5 generations of selfing again in backcross progeny.Select the inbred line of good seed redness in the offspring of selfing, isolated yellow seed inbred line is all eliminated, and namely cultivates the red corn inbred line with Fei Ruide blood source.
- 4. take the red corn inbred line that contains auspicious moral blood source as maternal, take the red corn inbred line that contains Fei Ruide blood source as the combination of male parent preparing hybrid, therefrom filter out the red corn hybrid seed of high-combining ability, plant its offspring's seed of red corn hybrid seed and remain red.
