Botany of Cucumis melo

10 botanical groups based on the diverse forms. Whitaker & Davis,2 Munger & Robinson,3 Robinson & Decker-Walters4 also contributed to Naudins1 classification which remained a basis for melon intraspecific classification with amendments being brought today. These taxonomic studies results to the 7 intra-specific groups of melons known present: agrestis (wild melon), cantalupensis (sweet melon), inodorus (winter melon), flexuosus (snake melon or snake cucumber), conomon (pickling melon), dudaim (mango melon or pomegranate melon) and momordica (snap melon). Africa is considered to be the centre of origin for melon because of the frequent occurrence of wild species of Cucumis with the same basic chromosome number n=12.5 The secondary center of origin of melon is in Turkey, Syria, Iran, Afganistan, India, Turkmenistan, Tadjikistan and Uzbeskistan.China, Korea, Portugal and Spain were also referred as the secondary centres of diversity for these species. Whitaker & Bemis6 also indicated that C. melo are found only in eastern tropical Africa south of the Sahara. In addition to the results, Pitrat et al.7 reported that wild types are commonly found in the Sudano-Sahelian area Furthermore the secondary centre of diversity stretch from Asia the Mediterran to Japan. Cucumis melo, which came in many different forms and uses, is one of the important horticultural crops worldwide and plays an important role in international trade. The immature and mature melon fruits are used as dessert and vegetables.5 Melon seeds are also eaten after being slightly roasted, and is also used to produce edible oils. Pest and different agents, such as bacteria, fungi and viruses are known to provoke diseases and great losses in melons. Their distribution and impact on melon plants vary around the world. Fusarium wilt, powdery mildew, Alternaria leaf blight and gummy stem blight are among the important fungal diseases known. Lecoq et al.8 discussed that some viral diseases that cause economic losses globally are Cucumber Mosaic Virus (CMV), Papaya Ring Spot Virus (PRSV), Watermelon Mosaic Virus 2 (WMV 2), Zucchini Yellow Mosaic Virus (ZYMV), Cucurbit Aphid-Borne Yellows Virus (CABYV), Squash Mosaic Virus (SqMV) and Watermelon Chlorotic Stunt Virus (WCSV).Pests such as the white fly, aphids, leaf miner and the fruit flyare different insect species known to infest melons. Damages caused by insect pest are either direct through insect feeding or indirect through transmission of viral diseases. White flies (Bemisia tabaci) known to transmit Geminiviruses as WCSV,9 while aphids are known to transmit both Luteo viruses as CABYV10 and Potyviruses as ZYMV.4 Leaf miners (Liriomyza spp.) caused damageon melons through feeding punctures while it larva bores leaf tissues.10 The melon fruit fly (Dacus spp.) also causes severe damage during oviposition of female fly in immature melon fruits.4
