NOVEL PLANT VARIETY BRASSICA CAMPESTRIS L. SSP. CHINENSIS HONGKYEONGCHAE, AND METHOD FOR BREEDING THE SAME

摘要

The present invention provides novel Brassica campestris L. ssp. chinensis Hongkyeongchae, and a seed thereof by abandoning an interspecific hybrid F₁ of Brassica campestris var. chinensis and Brassica koreana Lee var. redleaf for the stabilization of a hybrid embryo; back crossing a F₂ plant by using Brassica campestris var. chinensis as a seed parent; obtaining various strains of plants having the shape of conventional Brassica campestris var. chinensis and showing red color; obtaining a plurality of red Brassica campestris var. chinensis from the progenies obtained by back crossing various strains of B₁F₁ plants selected from the obtained plants with Brassica campestris var. chinensis; and carrying out strain acclimation and a self-incompatibility test, a seed productivity test and a local adaption test of a remarkable strain of a plant having the shape of conventional Brassica campestris var. chinensis and showing red color.
