Sixteen Meloidogyne isolates from tomato fields in California grown with resistant cultivars were multiplied on resistant tomato in a greenhouse. Of these resistance-breaking isolates, one was identified as M. javanica, and all others as M. incognita. The reproduction of the M. javanica isolate and four M. incognita isolates on six resistant tomato cultivars and on susceptible and resistant cultivars of pepper, sweetpotato, green bean, cotton, and cowpea was evaluated and compared to an avirulent M. incognita population in greenhouse pot trials. On resistant tomato cultivars, there were minor but significant differences between the resistance-breaking Meloidogyne isolates and between the different tomato cultivars. Of the other resistant crop cultivars, pepper was resistant to all isolates and green bean to all M. incognita isolates, while cotton and cowpea allowed reproduction of one of the resistance-breaking M. incognita isolates. The resistant sweetpotato cv. Bonita behaved like resistant tomato, allowing reproduction of all five resistance-breaking isolates but not of the avirulent M. incognita. Our results showed that variability exists among resistance-breaking Meloidogyne isolates, and that isolates overcoming resistance in tomato may also be virulent on resistant sweetpotato.

“…'NC05-198' is a rose-skinned, orange-fleshed variety being considered for release by the North Carolina Sweetpotato Breeding and Genetics Program, probably in 2016 (K. Pecota and G. Yencho, personal communication). 'Bonita' is a white-skinned, white-fleshed variety considered to be superior to 'O'Henry' (whiteflesh variety), and also has smoother root surface and a drier, sweeter flesh (La Bonte et al, 2011;North Carolina Crop Improvement Association, 2015). 'Orleans' is similar to 'Beauregard' in yield, skin color, flesh color, and sugar content but tends to have an elliptic and more consistent root shape than 'Beauregard' (La Bonte et al, 2012).…”

Studies were conducted in 2012 and 2013 to compare Evangeline to various sweetpotato (Ipomoea batatas) varieties (Bayou Belle, Beauregard, Bonita, Covington, NC05-198, and Orleans) for commercial production in North Carolina. In another study, microwaved and oven-baked ‘Evangeline’ and ‘Covington’ sweetpotato roots were subjected to analysis of chemical and physical properties [color, dry matter (DM), texture, and sugar] and to sensory evaluation for determining consumer acceptance. ‘NC05-198’ produced the highest no. 1 grade sweetpotato 600 bushels [bu (50 lb)] per acre and total marketable storage root yield was similar to ‘Bayou Belle’ and ‘Beauregard’ (841, 775, and 759 bu/acre, respectively). No. 1 and marketable root yields were similar between ‘Orleans’ and ‘Beauregard’. However, ‘Orleans’ produced more uniform roots than ‘Beauregard’, in which the latter had higher cull production. ‘Evangeline’ was comparable to no. 1 yield of ‘Bayou Belle’, ‘Orleans’, and ‘Covington’, which indicates the ability of this variety to produce acceptable yields in North Carolina conditions. ‘Covington’ had slightly higher DM than ‘Evangeline’, but instrumental texture analysis showed that these varieties did not differ significantly in firmness after cooking. However, microwaved roots were measurably firmer than oven-baked roots for both varieties. In this study, ‘Evangeline’ had higher levels of fructose and glucose, with similar levels of sucrose and maltose to ‘Covington’. Consumers (n = 100) indicated no difference between varieties in their “just about right” moisture level, texture, and flavor ratings, but showed a preference for Evangeline flesh color over Covington. Consumers in this study preferred oven-baked over microwaved sweetpotato (regardless of variety) and indicated that Evangeline is as acceptable as the standard variety Covington when grown in the North Carolina environment.

The reproduction and ability to cause root-galling of a California isolate of the peach root-knot nematode Meloidogyne floridensis was evaluated on seven sweetpotato (Ipomea batatas) cultivars and compared to a M. incognita race 3 and a M. incognita Mi-gene resistance-breaking isolate. The susceptible tomato (Solanum lycopersicum) cultivar ‘Daniela’ and the Mi-gene-carrying resistant cultivar ‘Celebrity’ were included as controls. Repeated trials were done in pots in a nematode-quarantine greenhouse at the University of California, Riverside. The three Meloidogyne isolates reproduced equally well on susceptible tomato. On Mi-gene resistant tomato, the reproduction and root-galling by M. floridensis was intermediate between the avirulent M. incognita race 3 and the resistance-breaking M. incognita isolate. The sweetpotato cultivars ‘Beauregard’ and ‘Diane’ were excellent hosts for all three Meloidogyne isolates. Cultivars ‘Bellevue’, ‘Burgundy’, and ‘Covington’ were resistant to these isolates. The cultivars ‘Bonita’ and ‘Murasaki-29’ were hosts for the M. floridensis and the resistance-breaking M. incognita isolate allowing an increase in nematode levels, while they were poor hosts resulting in a decrease in nematode levels for the M. incognita race 3 isolate. The study showed that M. floridensis can reproduce on tomato and some sweetpotato cultivars that are considered resistant to M. incognita.
