Abstract

‘Dixielee’ watermelon (Citrullus lanatus [Thunb.] Matsum. & Nakai) produces round striped fruits with intense red flesh. It grows vigorously and is resistant to race 1 anthracnose, Colletotrichum lagenarium (Pass.) Ellis & Halsted, and highly resistant to fusarium wilt, Fusarium oxysporum Schlecht. f. sp. niveum [E. F. Sm.] Snyd. & Hans. Because of its tough rind, firm flesh, attractive flesh color, high soluble solids, and excellent eating quality, ‘Dixielee’ is expected to help meet the need for additional high quality cultivars for commercial watermelon production in Florida and other producing areas as well as appeal to home gardeners who place a high priority on fruit quality.

Abstract

‘Sugarlee’ watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is an early season cultivar that produces high-quality fruits suitable for shipping or local market sales. It is resistant to anthracnose, caused by race 1 of Colletotrichum lagenarium (Pass.) Ellis & Halsted, and fusarium wilt caused by Fu-sarium oxvsporum Schlect. f. sp. niveum (E.F. Sm.) Snyd. & Hans. Because it matures early, ‘Sugarlee’ fits well into Florida’s commercial production program and might be used in conjunction with ‘Dixielee’ to lengthen the shipping season for any given production area or grower. ‘Sugarlee’ has performed well in the Southern Cooperative Watermelon Trials during the period 1977-1981 and is well-adapted throughout most of the watermelon production areas in the eastern United States.

Icebox watermelons have been available for some time, but have never attained commercial importance in the United States. In trials at Bradenton, Leesburg, and Live Oak, FL `Minilee' and `Mickylee' (mean weights of 7.5 and 10.0 pounds, respectively) matured earlier than other cultivars and produced yields equal to or better than other icebox cultivars. They had better internal quality and a higher level of resistance to Fusarium wilt than other available icebox cultivars. In storage tests `Minilee' was less susceptible to chilling injury than `Mickylee', `Sugar Baby', or `Baby Fun'; the flesh of `Mickylee' and `Minilee' was firmer and retained firmness better during storage than did the other two icebox cultivars. Icebox melons have appeal to individual home consumers and are well suited for shipment in cartons to both domestic and foreign markets.

Two newly released cultivars of small watermelons [Citrullus lunatus (Thumb.) Matsum and Naki], `Mickylee' and `Minilee', plus two other cultivars, Baby Fun and Sugar Baby, were stored at various temperatures from 1 to 21C for up to 4 weeks plus 1 week at 21C over two seasons. All cultivars were susceptible to chilling injury (CI) when stored below 7C; however, `Minilee' was less susceptible than the other cultivars tested. Chilling injury increased with storage length. Conditioning at 26C for 3 days before storage at 1C reduced CI and increased the percentage of marketable watermelons after storage. Decay percentage increased with storage time and was highest on fruit held at 1C where CI led to decay. The flesh of `Mickylee' and `Minilee' was firmer than that of the other cultivars tested and `Mickylee' and Minilee' retained their firmness better during storage. Total soluble solids concentration decreased with increased storage temperature. `Minilee' watermelons were superior to the other three cultivars in postharvest storage potential and exhibited the least CI and decay.
