Agronomic evaluation of Amarelo melon lines resistant to WMV-1, 1985> Nine WMV-resistant Amarelo melon lines obtained from the Centro Nacional de Pesquisa de Hortalicas's melon breedingr program and the WMV-susceptible Amarelo were field sown in 20 Aug 85 com a distrophic sandy oxisol, pH = 6.1 and M.O. = 1%, in Petrolina, PE, Brazil and harvested on 30 Oct 85. Mean temperature in oC (MT), Rainfall in mm (FR) and Relative humidity in % (RH) were as follows: (Aug (20-31): MT = 24.9 RF = 0.0 RH = 62.2; Sep: MT = 27.6 RF = 0.9 RH = 58.0; Oct: MT =27.7 RJH =14.1 RH =58.8. Plots were arranged in a randomized complete block design with ten treatments and four replication. Area/treatment was 80 m2, each plot consisting of four ten-hill row, twwo planta/hill. Two guard rows for each plot were sown with Amarelo. Harvestable plot area was 40 m2, consisting of two ten-hilol rows, two planta/hill. Rows were spaced 2,0 m and hills within rows 1,0 m apart. Crop management followed the usual procedures for the melon crop in the Vale do Sao Francisco, except that pesticides were not applied to the crop. After harvest, the fruits of each plot were counted, weeighted and measured, giving origin to the following parameters (Table 1): Production (PROD1), Average Fruit Weight (AFW2), Lenght;Diameter Relation (L/D3), and Flesh Width (FW4). Data on vbrix (Brix5) and Seed Production (SP6) were obtained from 3 fruits randomly collected in each plot. Aphid incidence (AI7) was visually assessed in each plot in the field at harvest time. Shoots and leaves of all plants were individually lassessed for WMV-1 presence by the Agar-gel Double Immune Diffusion Test, (WMV-18). Lines 85-242/697 and 85-242/286 were closer to Amarelo in terms of plant and fruit characteristics. Although not being the most productive, they resembled Amarelo in color, fruit size, fruit shape, brix and seed production. Lines 85-238/822 and 85-239/325, the most productive, had light yellow - colored fruits with low brix; Line 85-241/157, high yielding, presented a globular fruit shape (L/D3 = 0,913); Lines 85-241/624 and 85-241/2002 produced large fruits, not suitable for the brazilian market. The inability to recover WMV-1 from plant parts, after laboratory analyses, constitutes an evidence that all the resistant lines were able to stand natural infection at the Vale do Sao Francisco, PE, Brazil.
