U.C. PMR 45 fusarium wilt-resistant (Foml) is an andromonoecious, salmon-orange flesh, western shipping-type muskmelon, Cucumis melo L. It has value as a germplasm source for selection as well as for the development of commercial hybrids.
U.C. Top Mark fusarium wilt-resistance (Fom-1) is an andromonecious, salmon orange-fleshed, western shipping-type musk-melon (Cucumis melo L.) breeding line. It has value as a germplasm source for selection as well as the development of commercial hybrids.

U.C. PMR 45 and U.C. Top Mark fusarium wilt-resistant (Fom-3) are andromon-oecious, salmon orange fleshed, western shipping-type muskmelons (Cucumis melo L.) breeding lines. They have value as germ-plasm sources for selection as well as for the development of commercial hybrids.
–vermiculite formulation based on T. harzianum (CECT 20714) and the use of this agent as a nonformulated conidia suspension (direct inoculation) were both tested for their potential use as inocula for controlling fusarium wilt and promoting melon plant growth under in
or as a saprophyte in vegetal residues ( Louws et al., 2010 ). Chemical control of fusarium wilt is limited by the number of chemicals available and their effectiveness ( Martyn, 2012 ), and increasing concern about agriculture sustainability
Oriental melon ( Cucumis melo var. makuwa Makino) is an important germplasm resource of melon in China and is cultivated in Fuzhou (Fujian Province, China) for its delicious sweetness, high nutrient quality, and flavor. Fusarium wilt of Oriental
Three races of Fusarium oxysporum f.sp. lactucae, cause of fusarium wilt of lettuce, are known in Japan, where the pathogen was first observed in 1955. Fusarium wilt first affected commercial U.S. lettuce production in 1990 in Huron, Calif., but did not become a serious problem in the U.S. until 2001 when it reappeared in Huron and appeared in the Yuma, Arizona lettuce production area. Reactions of three fusarium wilt differentials (`Patriot', susceptible to races 1, 2 and 3; `Costa Rica No. 4', resistant to race 1, and susceptible to races 2 and 3; and `Banchu Red Fire', susceptible to races 1 and 3, and resistant to race 2) in a naturally-infected commercial field test and artificially-inoculated greenhouse tests, indicated presence of race 1 in the Yuma lettuce production area. Reactions of these differentials to an isolate from Huron confirmed the presence of race 1 in that area. Consistent with previous results from the U.S. and Japan, `Salinas' and `Salinas 88' were resistant to the Yuma and Huron isolates of race 1, whereas `Vanguard' was highly susceptible. Limited F1 and F2 data indicate that resistance to race 1 in `Costa Rica No. 4' and `Salinas' is recessive. `Calmar' is the likely source of resistance in `Salinas' and `Salinas 88'.
Cucumber ( Cucumis sativus L.) is one of the major greenhouse vegetables in the world and is very vulnerable to fusarium wilt caused by Fusarium oxysporum (FO) ( Ahn et al., 1997 ; Ye et al., 2004 ). Fusarium pathogen infects the roots and
We obtained estimates of genetic components of variance for resistance to Fusarium wilt in sweet-potato, through study of 40 randomly chosen plants of an intermating population and their respective open-pollinated offspring. The additive component accounted for virtually all of the genetic variance. Predicted advance from mass selection of the best 10% of the parents was 10.5% of the mean. The actual advance obtained in offspring of the selected plants was 13.9%. Heritability was estimated as .86.
