Genetic Analysis of Quantitative Traits, Gall Midge and Brown Spot Tolerance in Rice (Oryza sativa L.) Genotypes under Irrigated Ecosystem

P. Gonya Nayak, P. Madhukar, B. Laxmi Prasanna & B. Srinivas · International Journal of Environment and Climate Change · 2023

Gall midge and brown spot of rice are a fungal disease that affect both seedlings and mature plants. To investigate resistance of rice to this disease twenty nine rice cultures were evaluated under irrigated ecosystem at Regional Agricultural Research Station, Jagtial during khar...

Phenotypic Screening of Advanced Breeding Lines for Blast Resistance in Rice (Oryza sativa L.)

Umamahesh. P, P. Gonya Nayak, B. Laxmi Prasanna & T. Yella Goud · Journal of Experimental Agriculture International · 2024

Rice is predominantly grown in Asia, which accounts for about 90% of global production. Rice crop is affected by both biotic and abiotic stresses, biotic stresses such as blast, bacterial blight which significantly reduces the yields. Present study was conducted to introgress the...
