TL;DR
Morphological rice seedling traits at the three-leaf stage were significantly correlated with RGM oviposition preference, as validated using natural populations and an F2 segregating population, suggesting a role in antixenosis.
Rice gall midge, Orseolia oryzae (Wood-Mason), is a major pest of rice that causes significant yield losses in India. The present study was conducted during Kharif 2023 at Krishi Vigyan Kendra, Malyal, Mahabubabad district, Telangana, to evaluate four rice genotypes carrying genes conferring resistance to gall midge (W...

Background: Brown planthopper (Nilaparvata lugens) is a major insect pest of rice that causes severe yield losses through direct feeding and hopperburn. The emergence of virulent populations and increasing concerns over insecticide resistance necessitate the identification of rice germplasm with effective host plant re...

Local rice germplasm is a valuable genetic resource for developing bacterial leaf blight (BLB)-resistant and high-yielding rice cultivars. However, information on the resistance of Southwest Aceh local rice to Xanthomonas oryzae pv. oryzae (Xoo), particularly during the generative stage, remains limited. Previous studi...

Rice (Oryza sativa L.) is a crucial food crop, but its productivity is greatly affected by insect pests, particularly the yellow stem borer, Scirpophaga incertulas (Walker). This study evaluated rice cultivars for resistance to this pest under natural field conditions during the Rabi 2025-26 season at the Regional Agri...

Key traits such as anaerobic vigor index, shoot length and coleoptile length were identified as major contributors to AG tolerance, whereas the bending moment, section modulus and panicle weight were critical for lodging resistance and yield.

Bacterial leaf blight (BLB) of rice, caused by Xanthomonas oryzae pv. oryzae, is a major constraint on rice production, and the use of resistant genotypes is an important approach to disease management. The present study screened 40 rice genotypes for BLB resistance using morphological evaluation and molecular markers...
