Morpho-molecular Identification and Pathogenicity of Fusarium oxysporum Pathogens Associated with Vascular wilt in Cowpea (Vigna unguiculata L.)

A. M. Shahiba, V. G. Jayalekshmy, A. Sajeena & Arun Chacko · International Journal of Plant & Soil Science · 2022

Fusarium oxysporum (Fo), causes vascular wilt in cowpea is a serious pathogen, which leads to severe yield loss and high plant mortality. Variability among the pathogen is very low, due to the lack of sexual reproduction, and low mutation rate. In this study ten different isolate...

Studies on PCV, GCV, Heritability, and Genetic Advance in Rice Genotypes for Yield and Yield Components

Arun Chacko, V. G. Jayalekshmy & A. M. Shahiba · International Journal of Plant & Soil Science · 2023

The present experiment was carried out in twelve genotypes including IRRI introgression lines and a Japonica cultivar to analyse the genetic variability, heritability, and genetic gain. Significant differences were observed among the genotypes. All the traits under study recorded...

Gene Validation for Brown Plant Hopper Resistance in Rice Varieties Using SSR Markers

Arun Chacko, V. G. Jayalekshmy, K. Karthikeyan, Beena Thomas, S. Shanas & A. M. Shahiba · International Journal of Plant & Soil Science · 2023

The Brown Plant Hopper (BPH), Nilaparvata lugens (Homoptera: Delphacidae) is one of the most destructive insect pests causing significant yield loss in most of the rice cultivars of Asia. Marker-assisted backcrossing is used to introgress the genes for BPH resistance in which the...
