Agronomic evaluation of sweetpotato varieties
1995
Catanay, M.B. (Department of Agriculture, Tabaco, Albay (Philippines). Albay Experiment Station)
Twenty one varieties of sweetpotato were evaluated for agronomic performance at the Albay Experiment Station, Buang, Tabaco, Albay, Philippines from March to July 1993. Pest incidence was generally low and it has not been possible to measure significant differences in varietal resistance, except for resistance to gall mites. Introduced varieties tend to have less damage caused by gall mites than the traditional varieties Binoras and Tres Colores. Significant differences were obtained in shoot and marketable root yield. PNGL 390 gave the highest shoot yield of 23.68 t/ha. G88 produced the highest total marketable roots of 26.25 t/ha followed by OPS 37 and V37-151 with yields of 24.45 and 22.88 t/ha, respectively. All traits considered, G88 has the best chance of being accepted by farmers
