Beschreibungen/Notizen

• Twentyone genotypes of pyrethrum were studied for genetic variability. The highest genotypic and phenotypic coefficient of variations was recorded for cinerin II concentration at 55.53 and 57.27 followed by pyrethrin II at 48.97 and 48.99 lowest for total assay at 25.46 and 28.25, respectively. Six traits showed high heritability 94.01% to 99.90%, the highest being for pyrethrin II (99.90%). Pyrethrin I with total assay and pyrethrin II with jasmolin II were positively associated. Pyrethrin I and II made the highest direct and indirect contribution to total assay, hence may form a good selection criterion for flowers yields and qualitative traits.
