Hybrid cereal seed production

Disclosed is a method of producing hybrid seeds, in particular hybrid cereal seeds, comprising crossing a stand of shorter female (male sterile) plants (shorter than the fertile plants) with a stand of taller male fertile plants (taller than the sterile plants). The method comprises limiting the proportion of self-fertilized male seed in the final produced seed stock. In particular, the method limits the seed development on male plants after pollination to reduce or eliminate the proportion of self-fertilized male seed in the final produced seed stock. The method limits this proportion of self-fertilized male seed in the final produced seed stock, under a threshold value, preferably under a value to be compliant with a regulatory hybridity level. Limiting the seed stock of male plant comprises passing, at least once, a tool extending above the height of the shorter female plants, but below the level of the height of the taller male fertile plants, between anthesis, preferably end of anthesis, and harvest. The tool is intended to prevent or reduce normal development of these male fertile plants standing above this height. The crossing of female and male fertile plants comprises sowing the seeds as a mix or drilling male sterile seeds and male fertile plant seeds in separate lines. Preferably, said eliminating tool has means to apply an herbicide, preferably systemic, such as glyphosate.

METHOD FOR PRODUCING AGAVE CULTURES FOR TEQUILA

A method to expedite the growth of the agave plant by growing the plant tissue from a cell culture in a laboratory utilize incubator cells that are taken from the leaf of an agave plant and grown in a medium containing all the nutrients required for the production of new cells and the maturation of those new cells. The cells are then exposed to photosynthetic active radiation and fed with extra carbon dioxide, causing the cells to undergo photosynthesis and form the sugars that are found in a naturally growing agave plant. These cultivated cells are given an optimum amount of light and carbon dioxide to promote an unexpected and substantially higher growth rate than heretofore achieved.

TRANSCRIPTION FACTOR-MEDIATED PROMOTION OF DIRECT SOMATIC EMBRYOGENESIS
20220144900 · 2022-05-12 ·

A recombinant protein for use in a liquid culture medium for photo-autotrophic micropropagation of Cannabis sativa L. is disclosed. The recombinant protein comprises a fusion of a growth induction part and a uptake enhancement part. The growth induction part comprises an Arabinogalactan protein and/or a plant transcription factor associated with plant growth and development. The uptake enhancement part comprises a cell penetrating peptide sequence and a nuclear localization signal encoded by the peptide sequence SEQ ID NO 1.

AN IN VITRO RESCUE METHOD FOR IMMATURE EMBRYO OF AVOCADO

Provided is an in vitro rescue method for immature embryo of avocado, and the method includes: collecting immature avocado hybrid fruits, stripping immature zygotic embryos from the sterilized fruits; inducing maturation of zygotic embryos in different mediums selected according to the maturities of zygotic embryos; and avocado seed embryos growing to normal plants under light conditions after germination. Provided is a technology for the in vitro culture rescue of immature embryo of avocado, wherein the zygotic embryos at different developmental stages are induced to maturation under in vitro conditions, and after maturation, the seed embryos are induced to germinate and form healthy plants. The technology of the present invention can effectively improve the survival rate of hybrid avocado zygotic embryo, increase the success rate of hybrid avocado, rescue the hybrid offspring, reduce the loss of hybrid offspring, ensure the genetic integrity of hybrid group, and provide the key technology for hybrid breeding and genetic research of avocado, etc.
