Inheritance of seed coat color of Ethiopian mustard (Brassica carinata A. Braun)

Abstract

The inheritance of seed coat color was investigated in Brassica carinata in F1, F2, F3 and backcross progenies of crosses between brown- and yellow-seeded pure lines. Seed coat color in B. carinata was not influenced by xenia effect. Segregation pattern followed a mono-genic incomplete dominance inheritance model The occurrence of yellow/light yellow-brown seed trait in B. carinata may be due to an interaction between brown seed coat color gene and dominant repressor (Rp) genes. Key words: Brassica carinata, inheritance, seed coat color, dominant repressor
