GENETIC ENHANCEMENT OF MULTIPLE RESISTANCE TO FOLIAR DISEASES IN GROUNDNUT
1AICRP on Groundnut, Agricultural Research Station,
Chintamani - 563 125, Kolar, India
ABSTRACT
The PVC, heitability and genetic advance were high for all the foliar diseases. The genotypes
ICGV-99057, ICGV-00228 and ICGV-99068 showed resistant/ moderately resistant to late leaf
spot. The genotypes ICGV-00228, ICGV-99022, ICGV-00169,ICGV-99025, ICGV-00130and 99057
were found resistant/ moderately resistant to rust.While the genotypesICGV-99057, ICGV-
00169andICGV-99068 were found resistant/ moderately resistant to peanut stem necrosis disease.
The multiple resistant genotypes ICGV-99057, ICGV-00169 besides high potential also exhibited
good shelling percent and oil content. Hence, it is rewarding to incorporate resistance into good
agronomic types by hybridization and selection.
