Evaluation of Squash Cultigens in North Carolina

in HortScience

Yellow and zucchini squash (Cucurbita pepo L.) cultivars/elite lines (cultigens) were evaluated over two seasons (fall 1995 and spring 1996) in North Carolina. Different cultigens were tested over the 2-year period for both yellow and zucchini squash, although some cultigens were tested both years. Cultigen recommendations are based on yield, quality, disease resistance, and season grown. Yellow squash cultigens that yielded well include: Destiny III, Freedom III, Multipik, TW 941141, Liberator III (fall 1995); and HMX 4716, Superpik, PSX 391, Monet, Dixie, Picasso, and XPH 1780 (spring 1996). Superior-yielding zucchini squash cultigens were: TW 940981, Tigress, TW 940982, ZS 19, Elite, and Noblesse (fall 1995); and Leonardo, Hurricane, Elite, HMX 4715, Noblesse, and Tigress (spring 1996). Virus ratings for fall 1995 indicated that some transgenic plants with virus resistance withstood virus infection better than those without resistance. These were Freedom III, Destiny III, Freedom II, Liberator III, Prelude II, and TW 941121 (yellow), and Tigress, TW 940982, TW 940981, TW 940866 (zucchini). Virus-infected plants were assayed and viruses were determined to be zucchini yellow mosaic, watermelon mosaic II, and papaya ringspot.
