Abstract
AbstractRelationships between cashew nut yield and nine agronomic traits comprising seven reproductive (nut and floral) and two vegetative characters were studied in 59 selected cashew genotypes over three production seasons. Phenotypic correlation analysis showed that nuts per panicle (r = 0.844), number of nuts per tree (r = 0.988) and number of hermaphrodite flowers per panicle (r = 0.863) were positively correlated with nut yield and could be used as primary components for improving yield. Although correlation analysis showed insignificant association between nut weight and nut yield, path analysis revealed that the trait had significant positive direct effect (0.317) on nut yield. The subtle indirect effects of nut weight and leaf size on nut yield were more important than their direct effects and could be classified as secondary components. Both the direct and indirect effects of weight of the whole fruit and tree canopy on nut yield were negative and appeared detrimental.
