Genotypic variation in fruit characters in some genotypes of watermelon cultivated in Morocco
Abstract
Data from trial of five Moroccan landraces and four commercial watermelons varieties were used to evaluate the phenotypic variability and estimate genotypic parameters. Five characters were used for the estimation of the phenotypic and genotypic variability: fruit weight (FW), fruit length (FL), fruit width (FWd), fruit rind thickness (FRT) and total soluble solids content (TSS).The analysis of variance showed highly significant differences among genotypes in studied characters. The phenotypic coefficient of variation (CVP) ranged between (17 %) recorded for fruit width and (43%) for fruit weight and a highly and significant correlation was observed between FW and FL and FWd. Moderate to high values of broad-sense heritability were estimates for all characters measured except for fruit rind thickness. The TSS had the highest value of heritability (62 %). For all the characters, the genotypic correlation coefficient was higher than the corresponding phenotypic correlation coefficient which indicated that the apparent association might be due to genetic reason.
