1. If correlation coefficient is positive but the direct effect is negative or negligible indicates

(i) The indirect effect is due to correlations

(ii) Restriction to be imposed to nullify the undesirable indirect effects in order to make use of direct effects

(iii) True relationship and direct selection should be rewarding

(iv) Indirect selection is done for achieve greater yield response
