Abstract

Field trials were conducted in the 2014 rainy season at the Teaching and Research Farm of Bayero University, Kano (11°58’N and 8°25’E) and Agricultural Research Station Farm, Minjibir (12°11’N and 8°32’E). The objective of the study wasto evaluate the performance of improved sweetpotato lines with a view to identify those that may be adaptable with high yielding potential in the study area.The treatments consisted of 16 sweetpotato advanced lines: Centennial, AYT/08/055, TIS8164, TIS87/0087, NRSP12/097, UMUSPO/2, UMOSPO/1, SOLOMON-1, EA/11/022, EA/11/025, EA/11/003, UM/11/015, NRSP/12/095, UM/11/001, UM/11/022, and a local check (Kantayiidda). PotatoesThese were laid out in a Randomized complete block design with 3 replications. Significant differences were observed in number of roots per plant, number of marketable roots, number of pencil roots, flesh colour, root shape and root yield. Kantayiidda produced significantly (p<0.05) higher root yield (10315kg/Ha) than all other lines. Solomon-1, Umuspo/1, EA/11/022, UM/11/001 and TIS87/0087 were found to be promising among the advanced lines evaluated; thus could relatively compete with Kantayiidda local for adaptation and high root yield in the study area.
