Variability and phenotypic correlation among yield and some yield components in different genotypes of local radish (Raphanus sativus .L)

The experiment was conducted at Tayba Research Station, General Commission for Scientific Agricultural Research during 2011-2012, and 2012- 2013 growing seasons. Randomized block design with three replications was used to investigate phenotypic variances and to determine correlation of yield components of six local genotypes of radish. Significant differences between genotypes were appeared in diameter, length and weight of radish root. The correlation analysis revealed that root weight was positively and significantly correlated with both yield (0.964) and root diameter (0.274). Yield was positively and significantly correlated with root diameter (0.382). Root length was positively and significantly correlated with plant height (0.333) and number of leaves (0.329) per plant.
