An investigation was carried out at cashew research station under AICRP on cashew Ranasinghapur, Bhubaneswar, Khurda, during the year 2015-2017, to study the variability in thirty land races of cashew. It was found that, the heritability was highest in canopy area per m2 (99.82%) and minimum was recorded in canopy spread north-south (61.54%). The genetic variability with heritability gives a reliable picture of the genetic advance to be expected for the selection. More than 90% heritability was recorded in characters like, canopy area, total no of laterals, flowering laterals, duration of flowering, panicle length and panicle breadth, sex ratio, cashew apple weight and TSS. The characters like total flowers per panicle, staminate flowers per panicle showed maximum genetic advance. The genetic advance percentage of mean was recorded highest in numbers of perfect flowers per panicle (129.52) followed by sex- ratio (120.3). Estimation of different variable parameters will give insight into the inter-relationship among different traits and selection of promising traits are essential to formulate successful breeding programme.
