Different parameters were estimated to study the magnitude of genetic variability in two hundred diverse varieties/strains of coriander (Coriandurum sativum L.). The analysis of variance showed sufficient genetic variation among genotypes for all the twelve characters studied. Genotypic coefficient of variation, estimates of heritability and genetic gain were moderate to high for grain yield/plant, umbellets/plant, umbels/plant and 1000 seed weight, which indicated that response to selection would be very high for these yield components ultimately leading to yield improvement in this crop. However, for remaining characters medium to low coefficient of variation and low genetic gain was observed. Therefore, umbellets/plant, umbels/plant and 1000 seed weight should be given due weightage while breeding for higher seed yield.
