STUDIES ON BREEDING OF SWEETPOTATO VARIETIES ADAPTED TO DIRECT PLANTING. : 2. Variability of Daughter Roots Yield in Different Root Types.

Abstract

Variability of daughter root yield produced by directly planting sweetpotato was studied using typical strains belonging to direct-daughter type and indirect-daughter type, and the indirect-daughter type was considedered the most promising for direct planting because of its stable yield.
