Genetic variability and association analysis in strawberry (Fragaria x ananassa Duch)
Thirteen genotypes of strawberry were subjected to genetic variability and association analysis. The study revealed highly significant differences for all the characters studied, indicating the presence of substantial genetic variability. Phenotypic and genotypic coefficient of variation (PCV and GC...

Thirteen genotypes of strawberry were subjected to genetic variability and association analysis. The study revealed highly significant differences for all the characters studied, indicating the presence of substantial genetic variability. Phenotypic and genotypic coefficient of variation (PCV and GCV) was maximum for yield/hectare (42.58 and 42.27) followed by yield /plant (42.57 and 42.26), non-reducing sugar (34.44 and 34.39), number of flower/plant (29.37 and 29.09). While high heritability found in non-reducing sugar (99.7%) followed by fruit initiation (98.6%), yield/plant (98.6%), yield/hectare (98.6 %),average berry weight (98.4%), flower /plant (98.1%), fruit/plant (97.9%), TSS (97.6%), titratable acidity (97.6%), days taken from planting to harvest (96.4%) and anthocyanin content (95.2 %).
