Abstract The effects of Cylindrocladium black rot (CBR) of peanut (Arachis hypogaea L.) on yield, market quality and monetary value of the peanut crop were determined for Florigiant, NC 8C and two advanced generation CBR-resistant breeding lines. Percentage extra large kernels (ELK) and fancy size pods (FS) were decreased by CBR. The reduction of ELK has a minor effect on value. The reduction of FS had no effect on value. Reduction of value due to CBR was primarily the result of lower peanut yields. A highly significant proportion of the variation in yield and value was explained by regressions of yield and value on % CBR incidence measured approximately 1 wk before digging. Yield losses ranged from 250 to 450 kg/ha and value reductions for Florigiant and NC 8C were from $170 to $190/ha in 1980 and 1981 and from $270 to $290/ha in 1982 for each 10% CBR incidence. The relationships among CBR and yield, quality and value were similar for NC 8C and Florigiant. Therefore, NC 8C should sustain lower losses due to CBR than Florigiant because NC 8C is moderatley CBR-resistant.

Disease is a major factor limiting production of watermelons in Alabama. Gummy stem blight, anthracnose, and Fusarium wilt are three of the most serious diseases, causing reduced yields of melons in certain fields in Alabama. Although satisfactory control of gummy stem blight and anthracnose may be accomplished with the proper application of organic fungicides during normal weather conditions, no control measure is effective during periods of high humidity and high rainfall. The discovery that certain plant introductions were resistant to gummy stem blight and race 2 anthracnose led to development of multiple disease resistant breeding lines that produce high yields of excellent quality fruit. This research resulted in the 1991 release of AU-Golden Producer and Au-Sweet Scarlet varieties that are resistant to gummy stem blight, Fusarium wilt, and anthracnose (Colletotrichum laginarium race 2). Both melons are superior to current varieties of their type in yield, quality, and disease resistance.

Cucumber (Cucumis sativus L.) is one of the most popular vegetable crops grown in U.S. home and urban gardens. The objectives of this study were to identify cultivars and planting densities for high yield of container-grown cucumbers. Additional objectives were to determine the value of field trials for predicting cucumber performance in containers and to evaluate different plant types (dwarf-determinate vs. tall-indeterminate, gynoecious vs. monoecious, pickling vs. slicing) for container use and disease severity across cultivars. Fourteen cultivars and breeding lines were tested at three planting densities in two seasons for yield, quality, and disease resistance in field and patio trials. Significant differences were detected for seasons, cultivars, and densities. Yields were highest in the spring season compared with the summer season, and the best performance was obtained using three plants per 12 L container. There was a high correlation between patio and field trials, allowing extension specialists to recommend cucumber cultivars with high yield, high quality, and disease resistance based on field trial data. Home gardeners who want space-saving, high-yielding cucumbers with tender skin should consider a dwarf-determinate, pickling type that is monoecious. With monoecious type, no pollenizer is needed, and the harvest will be spread over more weeks than would be for gynoecious types.

`White Half Runner' is a popular green bean (Phaseolus vulgaris L.) cultivar in the southern Appalachian region of the United States. The cultivar is highly susceptible to rust and virus diseases. Nine breeding lines with `White Half Runner' parentage were compared to `White Half Runner' for rust tolerance, yield, and pod quality in 1998 and 1999 field trials at Crossville, Tenn. The BelTenn selections were developed by USDA plant breeders and the UT selections were developed by University of Tennessee plant breeders. Selections `BelTenn-RR-2', `BelTenn 4-12028', `BelTenn 4-12046', `BelTenn 4-12053', `BelTenn 5-2717' and `UT-96-3' were resistant to rust. Only `UT 96-4' had lower yields than `White Half Runner' in 1999. The BelTenn lines had slightly smaller pods, and the UT selections had larger and rougher pods than `White Half Runner'. `BelTenn-RR-2' wasreleased in 1995 as a breeding line with rust resistance and pod quality similar to `White Half Runner'. Further selection of BelTenn-RR-2 by a private seed company led to the naming of a cultivar named `Volunteer White Half Runner'.

Fusarium disease of oats reduces yield quality due to decreasing germination that is caused by then contamination of grain with mycotoxins produced by Fusarium fungi. The aim of this study was to characterize the resistance of naked breeding lines of oats to fungal grain infection and to contamination with T-2 and HT-2 toxins. Thirteen naked oat breeding lines and two naked varieties, Nemchinovsky 61 and Vyatskiy, as well as a husked variety Yakov, were grown under natural conditions in the Nemchinovka Federal Research Center in 2019–2020. The contamination of grain with fungi was determined by the mycological method and real-time PCR. The analysis of mycotoxins was carried out by ELISA. In oats, Alternaria (the grain infection was 15–90 %), Cochliobolus (1–33 %), Cladosporium (1–19 %), Epicoccum (0–11 %), and Fusarium (3–17 %) fungi prevailed in the grain mycobiota. The predominant Fusarium species were F. poae (its proportion among Fusarium fungi was 49–68 %) and F. langsethiae (29–28 %). The highest amounts of F. langsethiae DNA ((27.9–71.9)×10–4 pg/ng) and T-2/HT-2 toxins (790–1230 μg/kg) were found in the grain of husked oat Yakov. Among the analysed naked oat lines, the amount of F. langsethiae DNA varied in the range of (1.2–42.7)×10–4 pg/ng, and the content of T-2/HT-2 toxins was in the range of 5–229 μg/kg. Two oat breeding lines, 54h2476 and 66h2618, as well as a new variety, Azil (57h2396), can be characterized as highly resistant to infection with Fusarium fungi and contamination with mycotoxins compared to the control variety Vyatskiy.
