Hybrid seed production method for forage maize

The invention discloses a hybrid seed production method for forage maize. In the method, teosinte serves as a male parent and maize tri-crossed hybrid serves as a female parent to produce a forage maize SC2 seed in a hybrid way. The hybrid production comprises the following steps of: 1) sowing the male parents and the female parents at time intervals to obtain the male parents having blossom intervals and the female parents having the blossom intervals; 2) performing hormone spraying and tassel removal on the female parents having the blossom intervals obtained in the step 1) to obtain the tassel-removed female parents having lower plant heights and lower ear heights; 3) trimming the subtending leaves of the tassel-removed female parents having the lower plant heights and the lower ear heights obtained in step 2) to obtain un-pollinated female parents; and 4) collecting the pollen of the male parents having the blossom intervals obtained in the step 1), pollinating the un-pollinated female parents obtained in the step 3) by using the pollen and culturing the pollinated female parents to obtain the forage corn SC2 seeds. Experiments of the invention show that plant obtained by planting the forage maize SC2 seed obtained by the method of the invention is gramineous pasture having high quality.

Selective breeding technique of anthocyanin type purple corn

The invention relates to a selective breeding technique of an anthocyanin type purple corn, comprising the following steps: pyramiding anthocyanin dominant genes of a plurality of locus, and enablingthe anthocyanin dominant genes of the locus to be homozygous; then pyramiding large subtending leaves, high yielding, excellent quality and adversity character and breeding purple corn or purple waxycorn inbred line which has high anthocyanin content by early generation selection and a minimally invasive single kernel identification method; and selectively breeding the anthocyanin type pure purple genotype homozygous or dominant heterozygous corn--the purple waxy corn and the purple corn by matching the purple waxy corn with the purple waxy corn, matching the purple waxy corn with the purplecorn, matching the purple corn with the purple corn or matching the purple corn with other purple recessive character corns. A prepared single cross hybrid has the advantages as follows: 1. seed cases, aleurone layers, rhachises, the subtending leaves, filaments, tassels, anthers are purple and rich in anthocyanin, and stalks, medulla, leaf veins and leaves present purple colors of different degrees and all contain the anthocyanin; 2. the single cross hybrid not only can be used for producing the anthocyanin but also can be used as a fresh food; and 3. the single cross hybrid has high yieldingand can be cultivated on all soils which are suitable for common corns.

InactiveCN103120121AStrong environmental controllabilityEasy to operateHorticulture methodsPlant genotype modificationTasselControllability
The invention discloses a method for determining a thermo sensitive genetic male sterile line through sowing at different stages in a cold water treatment period. Seeds of a sterile line to be treated with cold water are divided into two parts, A and B, wherein the part A is sown on a certain day during April 20th and May 10th and served as an early sterile line, and the part B is sown 9-11 days after the part A is sown and used as a late sterile line; the parts A and B are sown and transplanted under normal field management, the plant morphological change of the part A is closely observed during the end of June and the beginning of July, and the part B is immediately and correspondingly barreled and put into a cold water treatment tank to be treated for 6-8 days and then is taken out during a flat pulvinus period of the part A; and the last and penultimate tassels which have a pulvinus distance of+/-1cm are selected, and the residual tassels are removed by scissors, so that the thermo sensitive genetic male sterile line is obtained. The method has the advantages of simplicity, efficiency, low cost, strong environmental controllability and convenience in operation.
