 en Response of Cabbage Cultivars to Black Rot Infection
Shimelis, H

Abstract

Yield stability of white cabbage (Brassica oleracea var. capitata) cultivars were assessed to identify high yielding and stable cultivar(s) with adequate resistance to black rot caused by Xanthomonas campestris pv. campestris. Field experiments were conducted with artificial inoculations for three years (1998-2000) in two locations and using 10 selected commercial cabbage cultivar(s). Stability was assessed via joint regression analysis and superiority analysis. The result indicated that cultivars Tenacity, Gideon and Gloria expressed average stability with high yield and adequate resistance. Cultivar Tenacity was selected for its greater mean yield and stability for advanced testing for resistance against black rot disease.
