Resistance studies in F4 segregants

Screening of 230 F4 segregants of cross DC 615 (Susceptible parent) × Dharwad local (Resistant parent) along with checks (Dharwad local, DC 615, DC 15, DCS 47-1 and C 152) was carried out against bruchids (Callosobruchus maculatus) at the Department of Genetics and plant Breeding, University of Agricultural Sciences, Dharwad. Out of 230 segregants, 36 were highly resistant, 43 moderately resistant, 110 least susceptible, 34 moderately susceptible and 7 were found to be highly susceptible.

Genetic variability is prerequisite for any crop improvement program as it helps breeders in selection process. For this purpose, present study aimed to estimate genetic parameters of eleven quantitative characters along with reaction for yellow rust resistance of 243 segregating lines of wheat during F4 and F5 generations derived from two crosses...

The simple sequence repeat (SSR) or microsatellite marker is currently the most preferred molecular marker because of its reproducibility and codominant nature. The aim of this study was to validate SSR markers for bacterial wilt (BW) and tomato leaf curl virus disease (ToLCV) in tomato. DNA isolated from the parents Mukthi and IIHR-2195 was used to validate five SSR primers already reported for BW and ToLCV. One primer SSR20 which showed good polymorphism and reproducibility among parents were selected for further validation in F3 and F4 population.
