Studies on genetic variability and heritability in gerbera.

Study was carried out for 30 genotypes of gerbera to evaluate variability, heritability and genetic advance for 11 characters during Jan 2008- Jan 2009. Appreciable amount of variability was observed among the genotypes for all the characters under study. GCV and PCV was observed highest for number of ray florets flower -1 (37.88 and 41.18, respectively), followed by leaf area. Genotypic coefficient for other characters ranged from 2.57 (flower stalk length) to 16.27 (vase life). Heritability ranged between 11.72 per cent to 89.79 per cent for flower diameter and leaf area, respectively. Genetic advance was highest for number of ray florets flower -1 (169.90) followed by leaf area (75.89).
