Abstract:
Seventy-eight genotypes of fennel (Foeniculum vulgare Mill.) were evaluated in a randomized block design with three replications at the research farm, S.K.N. College of Agriculture, Jobner (Rajasthan) for seed yield and quality parameters. The analysis of variance revealed significant differences between the entries for all the characters studied indicating the existence of variability among genotypes. The phenotypic coefficient of variation (PCV) was slightly higher than corresponding genotypic coefficient of variation (GCV) for most of the characters except total Soluble sugar content which indicates that environment has little influence on the character’s expression. The present study showed higher heritability values (>70% for most of the characters) ranging from 10.0 to 91.6%. High heritability coupled with high genetic gain and coefficient of variability was observed for umbels per plant, seeds per umbel, harvest index, crude fibre content and seed yield per plant, indicating a possible role of additive gene effect for the genotypic variance for these characters. Phenotypic and genotypic correlation coefficient indicated that seed yield per plant showed significant and positive genotypic association with total plant height, branches per plant, umbels per plant, 1000-seed weight, biological yield per plant and harvest index. Hence, the selection based on phenotypic performance for these characters would be beneficial for achieving the desired gain.
