Abstract

The present research was carried out in the horticulture farm at the Rajasthan College of Agriculture, MPUAT, Udaipur, from October 2019 to May 2020. The experiment field was carried out in randomised block design (RBD) with 22 genotype of Gladiolus. The data was collected for 13 quantitative characters from five competitive plants that were randomly chosen from each replication. Indicating the impact of environment on these features, the phenotypic coefficient of variation (PCV) was larger than the genotypic coefficient of variation (GCV) for all characters. High phenotypic and genotypic coefficients of variation was recorded as the corm per plant (g) (30.4423 and 31.8004), spike per plant (28.7050 and 30.2679), Weight of cormels per plant (26.6444 and 27.869) respectively. The estimates of heritability varied from 30.48 to 30.48 % for different characters under study. It was found high for all the traits except vase life and spike durability in field.

Conclusion

Based on the present investigation, the high magnitude of heritability (in broad sense) coupled with high genetic gain was observed for most traits exhibiting additive genetic effect. It was observed that PCV was higher than GCV for all the traits studied highest GCV and PCV is recorded as the corm per plant (g) (30.4423 and 31.8004), spike per plant (28.7050 and 30.2679), Weight of cormels per plant (26.6444 and 27.869) respectively.
