Genotypic, cytological, mean performance and correlation studied were performed using parents, MCU 5, CO 14, CO 17, TCH 1828, KC 2, KC 3, GISV 323, GTHV 15-34 and RHC 1409 at the Department of Cotton, Tamil Nadu Agricultural University, Coimbatore, during the year 2021. Four F2 population viz., MCU5 × KC3, CO14 × KC2, CO14 × KC3 and CO14 × GISV 323 along with standard check DCH 32 were also raised for jassid screening. The study made evident that resistant phenotypes would have low jassid population with injury grade for a genotype when it had higher amount of phenol, chlorophyll index, lower amount of sugars and proteins along with higher numbers of trichome length, trichome density and also higher number of abaxial, midrib and vein pubescent counts. Based on the findings and debate, breeders should create varieties with high resistance gen.. View More»
