Genetic variability studies in gladiolus (Gladiolus grandiflorus Linn.) under Chitrakoot condition

Abhishek Singh and Shiv Shankar Singh
Fifteen different genotypes of gladiolus were evaluated for sixteen characters to study the genetic variability, GCV and PCV, heritability, genetic advance for growth, flowering and physiological characters improvement in Gladiolus under Chitrakoot condition. The mean sum of squares due to genotypes showed significant differences for all characters. The magnitude of (GCV and PCV) were found highest for yield of spike (no.) per plant yield of spike (lakh no.) ha-1, specific leaf weight (SLW) and specific leaf area (SLA). The highest heritability was observed for character viz. Length of Pseudo Stem (cm) and leaf area per plant (cm-2), plant height (cm), number of leaves per plant, length of spike (cm) and leaf area index (LAI), vase life of cut flowers (days) Specific leaf area (SLA), days to sprouting, number of florets per spike, days taken to flower initiation, self life of cut flowers (days), yield of spike (no.) per plant, yield of spike (lakh No.) ha-1, specific leaf weight (SLW) and high genetic advance was recorded for specific leaf area (SLA) and leaf area per plant (cm-2).
