FIELD SCREENING OF SHORT DURATION PIGEONPEA LINES FOR RESISTANCE TO BACTERIAL LEAF SPOT AND STEM CANKER (Xanthomonas campestris pv. cajani)

Abstract

Thirty five determinate and non-determinate pigeonpea types of early duration were screened against bacterial leaf spot and stem canker (Xanthomonas campestris pv. cajani). ICPL 87 and ICPL 85017 in determinate and ICPL Nos. 84048, 85048, 85049 and ICPH.22 in non-determinate types were resistant to bacterial leaf spot. Among these lines, the non-determinate line ICPL 85049 showed resistant reaction to stem canker also. The other five lines showed moderate resistance to stom canker. In general, red-flowered types, whether determinate or non-determinate, were found more susceptible than yellow-flowered types.

Keywords: Pigeon pea, Varietal screening, Bacterial leafspot, Stem canker.
