Inheritance of resistance to damage by Thrips tabaci Lindeman (Thysanoptera: Thripidae) in cabbage

The inheritance of resistance in cabbage (Brassica oleracea var. capitata ) to damage caused by Thrips tabaci Lindeman was studied in progeny from four crosses between resistant and susceptible inbred lines. In two families sharing the same susceptible parent, the narrow-sense heritability was calcu...

Description
Summary:The inheritance of resistance in cabbage (Brassica oleracea var. capitata ) to damage caused by Thrips tabaci Lindeman was studied in progeny from four crosses between resistant and susceptible inbred lines. In two families sharing the same susceptible parent, the narrow-sense heritability was calculated to be high (> 90%), using the Warner method of calculation. The other two families, also sharing a susceptible parent, had very low narrow-sense heritability (0-11%). In three of the four families, however, the validity of the Warner calculations were called into question due to significant epistatic interactions.
