Abstract

Background: The green gram (Vigna radiata L.) is the major legume crop in India. Dry root rot(DRR) incited by M. phaseolina is a serious problem to the green gram production area in the world and India; Dry root rot has in recent years become a major obstacle to the successful and gainful growing of green gram, which can lead to significant losses in green gram production. The host plant resistance is the best alternative to management the DRR of the green gram, it is an economical and eco-friendly way to disease management. In the experiment, Twenty-five green gram germplasm has been tested for resistance to DRR, a serious disease caused by Macrophomina phaseolina. Methods: M. phaseolina sand maize meal inoculum was applied to the field in sufficient amounts to maintain the sick plot before planting green gram germplasm, each germplasm was planted in three rows of 5 m in length, maintaining a distance between plants of 10 cm, the incidence of DRR was recorded using a disease rating scale. Based on disease reaction, green gram germplasm was grouped into different categoriesResult: From 25 green gram germplasm, four germplasm showed a resistant reaction to dry root rot, namely IPM-02-03, G-2, MH-2-15, MUM-2, while this has been observed. Susceptibility of green gram germplasm to dry root rot such as RMG-26.
