| Abstract | Powdery mildew disease caused by the fungus Erysiphe polygoni D.C. is an important disease of mungbean. Loss can be more serious if the disease attacks at seedling stage. In this paper, we report genetics of the resistance to powdery mildew disease in mungbean using a recombinant inbred line (RIL) population derived from a cross between the susceptible parent “KPS1” and the resistant parent “VC6468-11-1A”. Five hundred and ninety-two RILs were developed by random descending from 200 F$_{2}$ plants. The population was evaluated against the fungus in field and greenhouse conditions. The data were analyzed following a nested design for selfpollinating plants to determine genetic heritability of powdery mildew resistance. The severity of the infestation was measured by using disease index (DI) and area under disease progress curve (AUDPC). Both values showed continuous distribution in the RILs. Under field conditions, the narrow-sense heritability of DI and AUDPC were 0.67 and 0.48, respectively. While under greenhouse conditions, the values were 0.68 and 0.62, respectively. The results suggested that the resistance is quantitatively inherited with high heritability and predominantly additive gene action. To develop powdery mildew-resistant mungbean varieties, the plant breeder can select for resistant lines by using standard selection procedures for self-pollinating crops, viz. pedigree selection, bulk selection, early generation testing, and single-seed descent. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
