Cucurbit Genetics Cooperative Report 10:105 (article 55) 1987
Lists of the known genes for the cucurbitaceae have been published previously in 3 installments (3, 4, 21) and a complete, updated list of cucumber genes as published in CGC No. 8 (5), In the interest of updating and collecting the information on watermelon in one place, following is a complete list of the known genes for Citrullus lanatux (Thunb,) Matsum & Nakai. We hope to continue this practice, and publish a complete list for watermelon every four years.
