STABILITY ANALYSIS IN BLOND PSYLLIUM (PLANTAGO-OVATA)

An experiment was conducted during the winter season of 1992-93 and 1993-94 to study stability in 12 promising genotypes ('RI 49', 'RI 87','RI 88', 'RI 89', 'MSB 2', 'MSB 4', 'MSB 6', 'MSB 8', 'Sel 10', 'GI 2', 'HI 2' and 'HI 5') of blond psyllium (Plantago ovata Forsskal) under 4 different environments. Variance due to genotypes, environments, genotypes x environment interaction and its linear and non-linear components were found significant for spikes/plant and seed yield. The genotypes 'RI 89' and 'GI 2' had high mean, regression coefficient around 1 and non-significant deviation from regression for seed yield. These genotypes were found suitable in different agroclimatic conditions of Mandor and Udaipur in Rajasthan.
