A NEW PLANT VARIETY OF BRASSICA CAMPESTRIS L. SSP. CHINENSIS HONGKYEONGCHAE AND METHOD OF BREEDING THE SAME

摘要

The present invention promotes stabilization of hybrid embryo by inducing interspecific hybrid F1 of Brassica campestris var. Chinensis. and Brassica koreana Lee var. redleaf. F2 plants are backcrossed by using Brassica campestris var. Chinensis. as a seed parent to yield plants in various pedigrees in existing Brassica campestris var. Chinensis. shape with red color. B1F1 plants in various pedigrees selected from the plants yielded in the previous step are backcrossed to Brassica campestris var. Chinensis. as a seed parent to obtain a lot of Brassica campestris var. Chinensis. with red color among progenies. The pedigree purification, verification of self-incompatibility, verification of seed production, and local adaption rearing test are repeatedly performed to plants in a superior pedigree in a Brassica campestris var. Chinensis. shape with red color to provide a novel Brassica campestris L. ssp. chinensis Hongkyeongchae of the present invention and seeds thereof.
