Abstract:

Groundnut is an important oilseed crop of India and biotic stresses cause heavy yield losses. Development of resistant cultivars is one of the important objectives of the maintenance breeding programmes of groundnut and utilization of molecular markers for identification resistant sources has become a handy tool for plant breeders. Keeping this in view, an experiment was carried to check the resistance source(s) against late leaf spot (LLS) and rust in 30 genotypes under field conditions. Screening revealed that seven genotypes were moderately resistant to LLS and five genotypes were moderately resistant to rust. Out of thirty SSR markers, 16 recorded allelic variation and the polymorphic information content (PIC) value ranged from 0 - 0.84. The SSR markers, IPAHM103, co-segregated with LLS and rust phenotype and PM375 showed general resistance to a wide variety of biotic stresses. Thus, these markers can be used for identification and transfer of positive alleles for these biotic stresses in molecular breeding programmes.
