Abstract
Analysis was carried out for studying the yield-component inter-relationship
in seventeen varieties of sweet potato. Determination of the coefficients
of simple and mutual correlations and path at the levels of the first and second
order components reveals that an increase in the length of vine causes significant
increase in tuber yield. But at the same time, the overall area of leaf should
not be allowed to increase, because this character bears a negative relationship
with yield. An ideal plant type with longer vines, w i i i i small, narrow and
deeply lobed leaves with appropriate orientation on the viue for effecting better
photosynthetic efficiency, should be aimed at for selecting potentially high
yielders.
