Problems solved by technology

However, unlike hybrid crop varieties, the seeds of most conventional self-bred crop varieties are easy to reproduce and produce, and the risk of seed production is small, which increases the difficulty of intellectual property protection of new varieties

Embodiment 1

[0029] Using Huang Huazhan as a material for intellectual property protection of a new species, the genome editing technology mediated by CRISPR / Cas9 engineering nuclease was used to edit the temperature-sensitive gene TMS5 in the genome of Huang Huazhan (HHZ), and create a thermosensitive dual-purpose nuclear sterile Huang Huazhan S with the loss of TMS5 function. (HHZ-tms5). Utilizing the "dual pressure selection method of natural low temperature environment and artificial low temperature environment" (Yang Yuanzhu, et al. Breeding strategy and progress of light-temperature-sensitive dual-purpose nuclear sterile line of Yangtze River early indica rice. China Agricultural Science and Technology Herald, 2004, 6 (6) : 36-40) stress selection, and bred Huanghuazhan male sterile line (HHZ-tms5) with low starting point temperature for fertility conversion, stable fertility, good fertility and good outcrossing. Select a base with ecological advantages for breeding, and carry out la...

Embodiment 2

[0031] Using Huanghuazhan as the intellectual property protection material of the new variety, the two-line GMS strain 1S was used as the female parent to cross with Huanghuazhan (HHZ), and Huanghuazhan was used as the recurrent parent for continuous backcrossing for 5-8 generations and then self-crossed. In the process of backcrossing, combined with TMS5 gene-specific marker detection and genomic background analysis of genome-wide markers (such as SSR, SNP, etc.), select the single plant that contains the tms5 allele and has the closest genome background to Huanghuazhan and backcrosses with Huanghuazhan until 99% of the background is the same as that of Huang Huazhan, self-breeding and breeding, further using the "double pressure selection method of natural low temperature environment and artificial low temperature environment" (Yang Yuanzhu, et al. Breeding strategy for early indica rice photothermosensitive dual-purpose nuclear male sterile line and progress. China Agricultu...

Abstract

The invention relates to crop variety breeding and preparation of market seeds, and particularly discloses a preparation method of a novel conventional cultivar for crops. According to the preparation method of the conventional cultivar for crops, provided by the invention, through breeding and production of mixed homogeneity seeds (produced seeds comprise selfed seeds of material A1 and hybrid of materials A1 / A2 ), the condition that illegal seed enterprises steal seeds for self propagation is effectively avoided, infringement action of conventional selfed crop new species is reduced to a certain extent, and the intellectual property protection force to the conventional selfed new species of the seed enterprises is reinforced.

Description

technical field [0001] The invention relates to the breeding of crop varieties and the preparation of commercially available seeds, in particular to the preparation of conventional crop seeds. Background technique [0002] The development of agriculture is inseparable from the development of the seed industry, and the support of the development of the seed industry is the selection and development of new crop varieties. With the development of the marketization of my country's seed industry and the entry of multinational seed industry groups, strengthening the protection of intellectual property rights for new crop varieties will encourage and support technological innovation in the seed industry, the cultivation of new plant varieties and the transformation of achievements, and ensure the protection of the seed industry market. Fairness and justice, healthy development, are of great significance. [0003] With the promulgation and implementation of a series of laws and regu...
