Abstract

The inheritance of resistance to leaf blight caused by Alternaria tenuissima was studied in pigeonpea (Cajanus cajan). The Fl, F:z, BCl and BC2 generations involving seven resistant and a susceptible parents were evaluated. The dominance of susceptibility in Fl generation and segregation into 3S:1R ratio in F2 indicated that resistance is governed by single recessive gene in each of the varieties used in this study. The monogenic nature of disease resistance was confirmed by back-eross analysis.
