Studies on genetic variability, heritability and genetic advance in marigold

Abstract

The present investigation on variability, heritability, genetic advance in twenty three marigold genotypes was carried out for plant growth and flower yield. The highest value of PCV and GCV was observed for number of flowers per plant (117.95 and 116.50, respectively). High heritability was observed for days to bud initiation (98.48) followed by days to first flower opening (98.36), number of flowers per plant (97.55), plant height (96.44), flower diameter (94.08), flower yield per plant (90.66).The estimates of genetic advance were comparatively maximum for number of flowers per plant (237.02%) followed by flower yield (105.37% per plant and 104.66%/ m2).
