Evaluating Field Pea Genotypes for Resistance against Key Insect Pests

Abstract

In the rabi season of 2020-21, a field trial was executed at the Breeder Seed Production Farm, JNKVV, Jabalpur, M.P., aimed at assessing the resistance of 71 field pea genotypes against Aphid, Leaf hopper, and Gram pod Borer. Through weekly observations and subsequent statistical analysis, genotypes were categorized into distinct resistance groups. Prominent findings revealed that JP-180, Matar Rangpur, and Aman 1-206 exhibited high resistance to aphids and pod borers. Additionally, Kashi Samriddhi, JP-180, and Matar Rangpur demonstrated resistance to leafhoppers. Conversely, B-22, DDR-39, and KPMR-485 displayed high susceptibility to Aphids, while Batri patiram, VL-3, and VL-3 were highly susceptible to Gram pod borer. KPMR-485, VL-3, and VL-1 were found to be susceptible to both Aphid and Gram pod borer. The study further revealed that the genotype KPMR-485 achieved the highest pea yield, closely followed by Jayanti and IPF-99-25. In contrast, Safed Batra Gudda, Matar Rangpur, and Aman 1-206 exhibited the minimum yield. These findings provide valuable insights into the resistance patterns of field pea genotypes, aiding in the selection of cultivars with enhanced resistance and productivity for sustainable agricultural practices.
