Abstract

The present experiment was carried out from November 2020 to April 2021 in the experimental block of the department of horticulture, Naini Agricultural Institute, SHUATS, Prayagraj. The field experiment was carried out in randomised block design (RBD) with eight genotypes of Gladiolus. The data was observed from five randomly selected competitive plants from each replication for 25 quantitative characters. The genotypes are White prosperity (V1), Advanced red (V2), Strong gold (V3), Jessica (V4), Nightmare (V5), Purple flora (V6), Trade horn (V7), Priscilla (V8). The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) for all characters indicating the influence of environment on these characters. High phenotypic and genotypic coefficients of variation was observed for Weight of daughter corm, Number of cormels per hectare, Number of corm per hectare, Number of days taken to first floret open, corm yield/plant, Weight of mother corm, Co
