During the last week of May and the first week of June 1987. we visited five cities (Beijing, Xi'an, Guilin, Yangshou, and Guangzhou) in the People's Republic of China and Hong Kong. As part of our trip, we gathered data and germplasm from a variety of cultivated cucurbits (Cucurbitaceae). We were unable to make germplasm collections of many common cucurbits, particularly bottle gourds (Lagenaria siceraria (Mol.) Standl.) and loofahs (Luffa acutangula (L.) Roxb, and L. cylindrica (L.) M.J. Roem.), because the fruits were sold in the markets only in the immature state. Even from mature fruits, the amount of seeds collected was small. Therefore, we are currently increasing this germplasm with controlled pollinations. We will be sending the increased seed to the USDA-ARS, Germplasm Introduction Office, Building 001, Room 232, BARC-West, Beltsville, Maryland 20705. These include collection numbers 367, 368, 369, 370, 372, 380, and 382 (Table 1).

Species collected in China and Hong Kong and their codes in Table 1 are: Benincasa hispida (Thunb,) Cog. (BEN), Citrullus lanatus (Thunb.) Matsum. and Nakai (CIT), Cucumis melo L. (CUC-M), Cucumis sativus L. (CUC-5), Cucurbita maxima Duch. ex Lam. (CUK-A), Cucurbita mixta Pang. (CUK-I), Cucurbita moschata (Duch. ex Lam.) Duch. ex Poir. (CUK-M), Cucurbita pepo L. (C UK-P), Cyclanthera pedata (L,) Schrad. (CYC), and Momordica charantia L. (MOM).
