Evaluation and characterisation of sunflower (Helianthus annuus L.) germplasm.

One hundred and ten accession of sunflower germplasm were characterized on the basis of qualitative trait and were evaluated for yield and yield components to study the variability for different quantitative traits. Highest genotypic and phenotypic -1 coefficients of variation were recorded for seed yield plant (56.5% and 57.0%) and 100-seed weight (25.6% and 27.7%) -1 respectively. High heritability coupled with high genetic advance over mean were recorded for seed yield plant (98.1% and -1 115.3%) and number of leaves plant (93.9%, 38.2%) followed by leaf lamina length, leaf lamina width, plant height, 100-seed weight, petiole length, and head diameter. Qualitative traits also showed wide variation among the accessions.
