Abstract

A field experiment was conducted to study the “Genotypic and Phenotypic correlation coefficient in twenty genotypes of Gladiolus for Gwalior region” during 2021-2022 at Department of Genetics and Plant Breeding, School of Agriculture, ITM University, Gwalior, Madhya Pradesh. In this experiment twenty genotypes of Gladiolus were planted for the evaluation and the results of investigation revealed that for yield improvement through selection emphasis should be given on the characters like Plant height, Spike length, Rachis length, No. of shoots per plant, No. of corms per plant. Especially the emphasis may be laid down upon the Plant height, Number of florets or Diameter of the floret, since these characters had highly significant and positive correlations with Spike length so a direct selection from genotypes will be more effective for improvement of this crop.
