Embodiment Construction

[0012] Experimental materials and methods

[0013] The breeding method of the new variety of hybrid cabbage radish plant as a new line wants to be implemented by the microspore mutation method. However, in the microspore culture developed by the present inventors, the average embryo emergence rate in each culture vessel was only 0.9 (Hong and Lee, 1995), so this method is not suitable as a mutation induction method. Therefore, an experiment of treating with 0.01 μg / L of NMU mutagen was carried out while establishing a culture method with a slightly higher embryo emergence rate. Select an experiment with more embryos out of multiple experiments, induce the embryos obtained from this experiment into plants, and collect seeds for the progeny. As a result, there were individuals with more seeds collected in indoor artificial hybridization than existing hybrid cabbage radish. (A project of the Ministry of Agriculture and Forestry (ARPC), the final report of "Research on the main ...

Abstract

The present invention relates to a method for breeding a novel plant variety of high fertility xBrassicoraphanus with stabilized seed productivity, and discloses a method for breeding a novel plant variety of xBrassicoraphanus, which involves performing a mutant treatment on xBrassicoraphanus seeds by treating the xBrassicoraphanus seeds with 0.01 [mu]g / L of mutagen NMU, sowing the xBrassicoraphanus seeds, gathering the xBrassicoraphanus seeds, sowing the xBrassicoraphanus seeds again, performing artificial crossing in an indoor area to check seed productivity, and checking the uniformity of the variety using an AFLP primer.

Description

technical field [0001] The invention relates to a new hybrid cabbage radish plant variety whose seed productivity has been improved. Background technique [0002] The present inventors have bred "hybrid cabbage radish (commonly known as: xBrassicoraphanus, genome: aarr, 2n=38)" as an intergenus hybrid plant between cabbage and radish, and obtained a patent right (Korean Patent No. 0492518, patent name : New hybrid cabbage radish variation plant and breeding method thereof, date of authorization: on May 23, 2005). Later, according to the confirmation of the present inventors, it was found that although the plant can be widely used as edible vegetables for seedlings, edible vegetables for immature plants, vegetables for wrapping rice, radish vegetables, vegetables for kimchi and health care food, etc., However, the two common problems of distant hybrids have not been fully resolved. [0003] The first is the problem of low seed productivity. Although the plant is capable of...
