Non-Destructive Fatty Acid Analysis of Cucurbit Seed
Cucurbit Genetics Cooperative Report 4:36 (article 18) 1981 Allen Gathman and W. P. Bemis University of Arizona, Tucson, AZ 85721 In breeding for higher linoleic acid content in the seed oil of the buffalo gourd, Cucurbita foetidissima, we have found that this character varies greatly within seeds from the same cross, due to heterozygosity of […]
Segregation for Resistance to Trifluralin Toxicity in Progeny from Crosses of Susceptible Cucurbita moschata Parents
Cucurbit Genetics Cooperative Report 4:35 (article 17) 1981 Adeoye A. Adeniji and Dermot P. Coyne University of Nebraska, Lincoln, NE 68583 Several herbicides are reported to be selective in cucurbits when soil-incorporated (1, 2). Among these are the dinitroanilines, for example, trifluralin (treflan). A recent finding by us on the response of progeny derived from […]

Report No. 4 Watermelon (Citrullus lanatus) A new watermelon disease in Tunisia Hager Jebari (Tunisia) CGC 4:30-31 (1981) Hypersensitivity to anthracnose infection in Citrullus lanatus B.B. Rhodes (USA) CGC 4:32-33 (1981)
Hypersensitivity to Anthracnose Infection in Citrullus lanatus
Cucurbit Genetics Cooperative Report 4:32-33 (article 16) 1981 B. B. Rhodes Edisto Experiment Station, P. O. Box 247, Blackville, SC 29817 Van der Plank (3) discussed the hypersensitivity reaction in plants as first defined by Muller. It includes the morphological and histological change that when produced by an infectious agent, elicit the premature dying of […]
