VARIABILITY PARAMETERS IN CORIANDER (CORIANDRUMSATlVUM L.)

Abstract

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.
