Evaluation of varieties and genotypes for growth and yield of gladiolus

Abstract

A field experiment was undertaken during rabi season of 2024-25 at Satpuda Botanic Garden, College of Agriculture, Nagpur (M. S.) to evaluate thirteen varieties and genotypes of gladiolus for their growth, flowering and yield. The experiment was laid out in a Randomized Block Design with two replications. The results revealed that, in respect of growth parameters, significantly the earliest sprouting was recorded in the genotype NG-2 and sprouting percentage of corms was observed maximum with the genotype NG-1 and variety American Beauty. Significantly maximum vegetative growth of the plant viz., height of plant and leaves plant-¹ was noted with the genotype NG-1 and variety PDKV Satpuda Purple, respectively. However, minimum period for the first spike emergence was exhibited with the genotype NG2 and spikes plant-¹ was counted significantly highest with the variety PDKV Satpuda Purple. In respect of spike quality parameters of gladiolus such as length of spike, florets spike-¹ and vase life of spike were found to be maximum with the genotype NG-1. However, significantly highest corm yield in respect of corms plant-1 was recorded with Pusa Suhagin and genotype NG- 2 noted highest weight of a corm.
