An experiment was conducted to study the correlation and path analysis of thirty cashew genotypes in Tanzania. Results indicated that nuts per tree had strong and positive direct effects on yield and also with yield they were significantly and positively correlated at each location and in combined analysis. The significant positive correlations between percentage out turn with yield was predominantly due to the positive favorable interaction of percentage out turn with nuts per tree as manifested by the indirect effects of percentage out turn on yield through nuts per tree at each location and in combined analysis. Thus nuts per tree and percentage out turn were components identified that are useful as criteria for selection in cashew, which could be used in breeding programs to improve the crop yield in diverse ecologies.
