Effect of Inoculum Density on Reproduction of Reniform Nematode Rotylenchulus Reniformis and on Root Development of Sweet Potato Cultivars
Date of Award
The effect of inoculum density on reproduction of the reniform nematode, Rotylenchulus reniformis, and on root development of sweet potato cultivars; W-152, Centennial, Porto Rico and Goldrush was studied under greenhouse conditions. The inoculum density had no significant effect on the root weight of the cultivars tested. The number of mature females on root systems was higher at the highest inoculum level and the number of eggs per female was significantly higher at lower densities. The number of eggs produced per root system at different inoculum densities was not significantly different on the cultivar Goldrush but was higher on the other cultivars as inoculum density was increased. Maximum eggs per root system was lowest on Goldrush and highest on Centennial.
