Abstract:
Chickpea (Cicer arietinum L.) is used extensively in developing countries for human nutrition due to its high protein content, for cattle feed, and for improving soil fertility due to its ability to fix atmospheric nitrogen into a form useable by plants. However, its yields are very low (approximately 0.8 t ha -1 ) due to several fungal diseases attacking the crop throughout the growing season. Among these diseases, Ascochyta blight (AB), Botrytis grey mold (BGM), Fusarium wilt (FW), and dry root rot (DRR) are destructive and cause severe losses in grain yield worldwide. Growing resistant cultivars is the most economical way to manage these diseases. Cultivars resistant to FW are available, but they are susceptible to other diseases. Similarly, the available cultivars moderately resistant to AB, BGM, and DRR are susceptible to FW. Therefore, our quest continues to identify chickpea accessions with multiple disease resistance that could be used in breeding resistant cultivars to successfully combat these four diseases. Through this study, 211 chickpea accessions were screened for resistance to these diseases using standard protocol under the controlled environment of a greenhouse. The accessions were selected to represent the diversity of the entire collection of chickpea germ plasm. Combined resistance to BGM and FW was found in 11 accessions, 3 were moderately resistant to both FW and DRR, 2 were moderately resistant to both BGM and DRR, 1 was moderately resistant to both AB and BGM, 46 were resistant to FW, and 6, 3, and 55 accessions were moderately resistant to DRR, AB, and BGM, respectively.
