Abstract

The present study was done in a sub-temperate region of Himachal Pradesh for different
quantitative characters in different gladiolus genotypes regarding the assessment of variability, the
transmissibility of characters, interrelationships between traits and whether they are impacting yield
trait directly or indirectly. Identifying key traits essential for selection and crop improvement is a
crucial step in any successful breeding program. This study, therefore, played a vital role in
recognizing traits such as corm fresh weight, cormel fresh weight, and cormel number per plant
which showed significantly high values of GCV and PCV with the highest estimates of heritability
and genetic gain and traits like the number of days it took for spikes to emerge, the length of cut
spikes and rachis, leaves produced per plant, vase life, floret diameter, corm diameter and cormel’s
fresh weight as they were proved to positively and directly enhance florets yield per spike.
