Morphological Characterization of Sesame Germplasm in Semi-arid Condition of Delhi

Abstract

The base line for sesame improvement is to evaluate that diversity among
trait of importance. Total 696 germplasm of sesame conserved in gene bank of ICAR-
NBPGR were evaluated for morphological traits under augmented block design during
kharif season of 2017-18 at ICAR-NBPGR Experimental Farm, Issapur and New Delhi.
Analysis of variance revealed significant difference among genotypes for all the ten
characters studied. IC500816 found promising for early flowering (26 days) while very
late flowering observed in IC208657 (75 days). Higher yield per plant recorded in
IC501018 (47.00 gm) and while maximum tallness recorded in IC204843 (226 cm). Highest
no. of capsule per plant found in IC023271 (195.00) and maximum no. of locules per
capsule identified in IC132182 (20). Violet- purple corolla and blackish seed observed
in IC208662 genotype. Phenotypic coefficient of variation (PCV) found higher than
genotypic coefficient of variation (GCV) for most of the characters studied indicates the
role of environmental variance in the total variance. High heritability was recorded for
plant height and capsule per plant.
