However, there are also some disadvantages, such as the problem of super sweet and waxy (sh2wx): one is the appearance of the ears of this sweet and waxy grain mixture, especially when it is processed into frozen fresh corn, the sweet grains in it are in the form of blisters, When processed into vacuum-packed corn ears, it is also easy to produce sweet kernels collapse, which is quite diff...

Abstract

The invention relates to a novel sweet-waxy corn and a utilization method thereof. According to the invention, sweet-waxy mutant grains are used as original materials, a sweet-waxy fresh corn inbred line is bred, the novel sweet-waxy corn is obtained, and each grain of the sweet-waxy corn has the sweet and waxy characteristics; the identification standard of the phenotype of the sweet-waxy mutant grains is that the grains are sunken, are fuller than sweet corns, have farinaceous endosperm and are non-waxy, non-transparent, non-crumpled, lusterless in epidermis and crumple-free, and the sweet-waxy fresh corn is sweet and waxy in a real sense, that is, each grain has the sweet and waxy characteristics in a fresh eating period. Due to the fact that the inclusion of sweet-waxy fresh corn seeds is greatly increased compared with that of super-sweet corn, especially compared with that of double-recessive super-sweet corn, the germination rate is high, the germination potential is high, emergence is easy, seedlings are robust, and the problems that the double-recessive super-sweet corn and the super-sweet corn are low in germination rate, low in emergence rate and low in seedling protection rate and seedlings are thin and weak are solved.

[0041] Example 1 Sweet-type fresh food corn and hybrid

[0042] 1. Artificial mutagenesis of sweet fresh food corn

[0043] Using existing artificial mutagenesis technology (see Zhou Hong Sheng, Maize Seeds, China Agriculture Press, 2000, 217-219. The probability of recessive mutation is about 0.1%), mutagenesis with methyl sulfonate (EMS) The pollen of the 玉沉沉 3 (Liaonian Audit No. 490). Specific method is to treat pollen mutagenesis by 10 times the pollen volume of EMS and pollen mix, shake once every 3 minutes, after treatment 45min, apply a brush to the flush that has been packaged in advance, pollination 30 ears, and then The bag is isolated, and the mutagenesis 1 generation (M1) seed is obtained.

[0044] The mutagenesis 1 generation (M1) seed, self-tracing, and mutagenesis 2 generation (M2) cutting. According to the grain depression, the super-sweet corn is full, endosperm powder, non-wax, opaque, non-wrinkled, epidermalless, wrinkled expression characteristic looks for sweet mutants (granules) to obtain 7 grains of mutant particles.

[0045] 2. Expressive identification and taste verification

[0046] Size mutant grains, self-suggest, continue to make phenotype identification of harvested cuttings according to the phenotypic characteristics of sweet fresh food corn; next generation of seeds, self-sufficiency, fresh food taste, with a sweet and 口That is, a technique indicator of a hidden mutation, relying on grain expression type, non-quarantined technical indicators, which distinguishes the known SU1, DU, SH2, WX mutant).

[0047] 3. Breeding of Sweet-type Fresh Corn Self-communication

[0048] Continue to choose self-sufficiency until pureness, select SW56 and other sweet corn self-communications and sister system.

[0049] 4. Preparation of sweet and glutinous fresh food corn

[0050] Take the sweet self-intersection SW56 and SW60 (Embodiment 2) as the parent, the group is equipped with a sweet corn sister system hybrid.

[0051] 5. Implementation effect

[0052] (1) F1 commercial ear grain form consistent. Solved the phenomena of the appearance of sweet and glutinous freeze or vacuum packaging processing.

[0053] (2) The taste effect is sweet and. Sweetness is quite in super sweet corn. It is even more soft, juicy, and more juicy. After cooling, the endosperm does not harder, and the old cooked is not blooming.

[0054] (3) More andd to super sweet corn endosperm, there are many solid content, and the nutritional value is improved.

[0055] (4) There are many endosperm dry materials, and the seed performance is quite equal. High germination rate, strong budness, germination, arch soil, normal seedlings, healthy growth and strong resistance.

[0056] Example 2

[0057] 1. Artificial mutagenesis of sweet fresh food corn

[0058] Using existing artificial mutagenic technology (see Zhou Hong Sheng, Maize Seeds, China Agriculture Press, 2000, 217-219;) Pollen in national jade 2010014. Specific method is to treat pollen mutagenesis by 10 times the pollen volume of EMS and pollen mix, shake once every 3 minutes, after treatment 45min, apply a brush to the flush that has been packaged in advance, pollination 30 ears, and then The bag is isolated, and the mutagenesis 1 generation (M1) seed is obtained.

[0059] 2. Expressive identification and taste verification

[0060] Seeding seeds (M1), self-sustaining last year, self-tracing, and acquisition of 2 generations (M2) cutouts. According to the grain depression, the super-sweet corn is full, endosperm powder, non-wax, opaque, no shrinkage, glossless, wrinkled manifest characteristics, find sweet mutants (granules), and obtain sweet-type mutant particles 5 tablets.

[0061] Seeding the mutant grain, self-sustain, self-suggest, and obtaining single ear, and continues to make phenotype identification for harvested cuttings; next generation of spikes, self-tracing, fresh food taste, with both sweet and 口口Sweet-shaped fresh corn mutant.

[0062] 3. Breeding of Sweet-type Fresh Corn Self-communication

[0063] Continue continuous self-sufficiency until the various characteristics reach pure, and select SW60 sweet corn self-communications and sister system.

[0064] 4. Preparation for sweet and glutinous fresh food corn

[0065] Taking the glutinous corn self-exchange department Shennong 509 (Shen Jing 3's motherhood) as the motherhood, with sweet self-tax SW60 as the father, the group is equipped into a sweet and glutinous corn.

[0066] 5. Implementation effect

[0067] (1) F1 commercial ear grains, glutinous glutinous glutinous glutinous granules = 3: 1, with a sweet and glutinous taste. The F1 commercial ear grain is a parent based on the teleconcuts in the jarm, with the sweet type of self-trail, and the group is equipped into the first generation of hybrid.

[0068] (2) The sweet glutinous glutinous glutinous glutinous grains in the ear is more full, the difference between the sweet globacid and the glutinous particles is reduced during the fast freezing or canned, and the appearance has improved.

[0069] (3) Sweet glutinous gluness is more fulfilled than super sweet corn endosperm, has more solid content, and the nutritional value is improved.

[0070] (4) There are many endosperm dry materials, and the seed performance is quite equal. High germination rate, strong budness, germination, arch soil, normal seedlings, healthy growth and strong resistance.

[0071] Example III, Sweet-type fresh food corn variety breeding

[0072] 1. Breeding of Sweet-type Fresh Corn Self-communication

[0073] Using existing hybridization techniques, the Sw60 of the Sweet Fresh Food Corn Self-communicate SW60 is a non-rotation, with the reincarnation of the Shenlu 350 (Shen Luo No.7, the father), and returns the return. First, the SW60 is hybridized to the parent, starting from the second generation, and will return to the parent for the Qin 350. After 5 rounds, it is baked into a sweet and eaten. The seed grain is depressed, and the super-sweet corn is full, endosperm powder, non-wax, opaque, not wrinkled, the epidermis, no wrinkles. After fresh food, it has a sweet and sense. Sweetted fresh food corn self-communications SW350.

[0074] 2. Preparation of sweet and glutinous fresh food corn

[0075] Taking sweet self-intersection SW350 and SW60 (sweet self-intersection, Example 2) for the motherhood and the parent, the group is equipped with sweet corn hybrids.

[0076] 5. Implementation effect

[0077] (1) F1 commercial ear grain form consistent. Solved the phenomena of the appearance of sweet and glutinous freeze or vacuum packaging processing.
