Embodiment 1

[0016] A binary hybridization method of quinoa, comprising the following steps:

[0017] 1) Breeding of quinoa female parent plant: In the winter of 2017, in the Yuanping experimental greenhouse, there was a quinoa flower on Jiaqi Baiqin No. 8 (the whole plant was green), showing the characteristics of flower opening, and the pistil matured before the stamen. Quinoa flowers serve as the female parent plant for binary crosses.

[0018] 2) Use the fuchsia quinoa numbered JQ-778 as the male plant to pollinate the female plant, and then produce seeds. In the spring of 2018, the fuchsia F1 plant was sown in the Pinglu Jiaqi experimental field, proving the success of the hybridization .

Embodiment 2

[0020] A binary hybridization method of quinoa, comprising the following steps:

[0021] 1) Breeding of quinoa female parent plants: use ethyl methanesulfonate solution with a concentration of 0.8 mol / L to soak the original quinoa seeds M 1 6 hours, shaking on a shaker for 6 hours, washing with water for 2 hours, sowing seedlings in the treated seed plugs, and transplanting the seedlings to the field after they grow to 8 true leaves. The batch processing date is June 5, 2017, June Transplanted to the Pinglu experimental field on the 27th, and harvested the seeds on September 10. M 2 , on March 25, 2018, M was sown in Yuanping Greenhouse 2 After flowering, a plant whose pistil matures before the stamen and the flower is fully opened is selected as the hybrid female plant.

[0022] 2) Reasonable sowing date: in the pair M 1 During the mutagenesis period, the male plant was planted by sowing at intervals. In this example, the Jiaqi quinoa resource with the number JQ-00077 was...

Abstract

The invention discloses a binary hybridization method of quinoa and relates to the technical field of crop breeding. The binary hybridization method solves the problem that the quinoa hybridization has strong labor intensity, incomplete castration and pistil damage causing hybridization failure. The method comprises: selecting female and male plants needing hybridization, and carrying out binary hybridization on quinoa through an artificial pollination method, wherein the flower of the female plant used by binary hybridization has a pistil mature in advance of a stamen and is fully opened whenthe pistil is mature and the stamen is immaturate and the pistil is fully exposed. The specific quinoa female plant can break through the trouble of the complicated artificial emasculation and laterbreeding, and realize hybridization through matching of a breeding target and a male parent. The method breaks through the quinoa breeding technology and is fast, accurate and efficient.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to a binary hybridization method of quinoa. Background technique [0002] Quinoa (Chenopodium quinoa willd) belongs to Chenopodiaceae, dicotyledons, monoecious, self-pollination, outcrossing rate is reported to be 5-10%. Quinoa as a food crop has been paid attention to by breeders for nearly 30 years, and only in the past 10 years have breeders carried out cross-breeding of quinoa. However, the hybrid breeding method adopted at present is still based on artificial castration, and then artificial pollination to obtain hybrid offspring, by selecting homozygous inbred lines with excellent traits from the offspring. [0003] From the point of view of the bred hybrid varieties, the hybrid advantage of quinoa is obvious, so the hybrid breeding of quinoa will be an indispensable and important way to change the shape of quinoa in the future, improve the yield, improve the quality, an...
