STABILITY FOR SEED SIZE IN BUNCH GROUNDNUT (ARACHIS HYPOGAEA LINN.)

Published on

Twenty nine bunch groundnut genotypes were evaluated under four environments
to estimate the stability parameters for 100 seed weight. Both predictable and non
predictable components of genotypes x environment (G x E) interaction were
important for expression of this trait. However, .linear portion was significantly
higher than nonlinear portion. Seventeen genotypes showed linear and 11 genotypes
nonlinear sensitivity. Both the components of G x E interaction were present in
gem>type JB-224. The bold seeded genotype EC-100827 and small seeded genotype
JB-215 showed wider adaptation. The bold seeded genotype JB-210 and small seeded
genotype J-18 were highly responsive and suitable for favourable environments.
Bold seeded genotype J-17, GG-2, J(E)-l, JB-223 and CGC-3 as well as small seeded
genotypes ICGS-11, J-11, NRGS-4, J(E)-l, JB-187, J(E)-336 and GAUG-1 were suitable
for adverse environments.
