Stability analysis for economic traits in blond psyllium (Plantago ovata Forsk.)

Published on

Stability analysis was carried out with thirty six genotypes
of isabgol (Plantago ovata Forsk) under three environments
to identify stable genotypes that could be cultivated
uniformly under varied environmental conditions for yield
and yield attributing traits. Pooled analysis of variance for
stability indicated that all the genotypes of isabgol were
highly significant for all the characters indicated that
materials selected possessed sufficient genetic variation
for all the traits studied. Mean squares arising due to
genotype, G x E interaction and E + (G x E) were found
significant for all the traits. Sufficient genotype x
environment (linear) were exhibited by all the genotypes
for all characters. The genotype RI-158 was superior in per
se performance and stability for seed yield suggesting its
suitability for inclusion in future breeding programme for
development of stable variety. The genotypes, namely, RI-
138, RI-3004, RI-166, RI-155, RAUI-Ja-2, RAUI-Ja-3, RAUI-B,
RI-89, HI-2, GI-4 and Niharika were found suitable for high
yielding environments, while genotypes, GI-2, RI-1(9808)
and RI-142 were best in poor environments for seed yield
