CHARACTERIZATION AND EVALUATION OF SUNFLOWER (HELIANTHUS ANNUUS L.) GERMPLASM

Published on

One hundred and ninety six germplasm accessions of sunflower were evaluated for yield
and yield components to study the extent of variation in different quantitative traits. The
germplasm accessions were also characterized on the basis of qualitative traits. Highest
phenotypic and genotypic coefficients of variation were recorded for lOO-seed weight,
followed by seed yield, oil yield, number of filled seeds per plant, plant height and head
diameter. Heritability was highest for lOO-seed weight (72.0%), followed by seed (68.60/.),
number of filled seeds per plant (64.9%), oil yield (64.1%), and oil content (56.0%). Genetic
advance as per centof mean was highest for oil yield (50.7%), followed by seed yield (50.6%)
and numberoffilled seedsperplant (33.9%). Qualitative traits also showedwide variability
among the genotypes.
