【 摘 要 】

A study to evaluate the resistance and performance of six varieties of pigeon pea (Cajanus cajan [L.] Huth) against major insect pests was conducted at Bunda College of Agriculture, Malawi during the 2017/2018 cropping season. The experiment was arranged in a Randomized Complete Block Design (RCBD) with three replicates. Results indicated that cultivars varied in number of days to flowering with ICPL 87105 (82 days) and ICPL 93026 (97 days) flowering earlier than the rest of the treatments. In addition, significant differences (p-1) and ICPL 9145 (1009.6 kg ha-1) having higher grain yield (kg ha-1) and less damaged pods than the rest of the cultivars. Cultivars ICEAP 00040 and ICEAP 01514/15 had significantly lower damaged pods 23.08% and 26.55% respectively as compared to other cultivars followed by ICPL 87105, ICPL 9145 and ICEAP 00557 respectively. There is potential of realizing high yields in late maturing varieties such as ICPL 00040 and ICEAP 9145 grown without the application of any pesticide.
