Consensus Document on the Biology of the Capsicum Annuum Complex (Chili Peppers, Hot Peppers and Sweet Peppers)
Capsicum annuum L. is a dicotyledonous flowering plant commonly grown worldwide, with many general names in English, such as hot pepper, chili, chilli or chile pepper, and as well sweet pepper and bell pepper. Sometimes the plant is just called pepper, which however is often reserved for the earlier known Asian Piper nigrum (black pepper, white pepper) in…
Read MoreConsensus Document on the Biology of Cassava (Manihot esculenta Crantz)
Three subspecies of cassava have been recognized: Manihot esculenta ssp. esculenta is the cultivated strain, and M. esculenta ssp. flabellifolia and M. esculenta ssp. peruviana are wild forms (Allem, 1999, 2002). In this document, “cassava” will be used to refer to the cultivated strain, M. esculenta ssp. esculenta. Common synonyms in other languages are manioc (French), mandioca, macaxeira, and aipim (Portuguese), yuca (Spanish), and manioca (Italian). Attachments: Biology_of_Cassava
Read MoreConsensus Document of the Biology of Common Bean (Phaseolus vulgaris L.)
The genus Phaseolus is large, including approximately 80 cultivated and wild species, but P. vulgaris is the most widely cultivated species (Purseglove, 1968; Freytag and Debouck, 2002; Bailey, 1975; Porch et al., 2013). The most closely related species to P. vulgaris are P. albescens, P. coccineus, P costaricensis, P. dumosus, P. parvifolius, and P. persistentus (Table 1.) (Chacón et al., 2007;…
Read MoreConsensus Document on the Biology of Cotton (Gossypium spp.)
Generally cotton refers to four species of the genus Gossypium L. apparently domesticated independently in four separate regions, in both the Old World and the New World (Sauer, 1993; Brubaker et al., 1999c). The word is derived from the Arabic “quotn”, “kutum” or “gutum” and refers to the crop that produces spinnable fibres on the seed coat (Lee, 1984;…
Read MoreConsensus Document of the Biology of Cowpea (Vigna unguiculata (L.) Walp.)
Cowpea (L.) Walp.) is grown in tropical Africa, Asia, North and South America mostly as a grain, but also as a vegetable and fodder crop. It is favoured because of its wide adaptation and tolerance to several stresses. It is an important food source and is estimated to be the major protein source for more…

Maize, or corn, is a member of the Maydeae tribe of the grass family, Poaceae. It is a robust monoecious annual plant, which requires the help of man to disperse its seeds for propagation and survival. Corn is the most efficient plant for capturing the energy of the sun and converting it into food, it has a great plasticity adapting…
Read MoreConsensus Document on the Biology of Papaya (Carica papaya)
Papaya, Carica papaya L., is an almost herbaceous (succulently soft-wooded), typically unbranched small tree in the family Caricaceae. Europeans first encountered papaya in the Western Hemisphere tropics by at least the early 1500s (Sauer, 1966), and various interests were soon disseminating it widely (Ferrão, 1992). Papaya is now cultivated worldwide in tropical and subtropical climates mainly for its melon-like fruit.…
Read MoreConsensus Document on the Biology of Solanum tuberosum subsp. tuberosum (Potato)
This consensus document addresses the biology of the potato (Solanum tuberosum subsp. tuberosum). It contains general information on the taxonomy, morphology, and centre of diversity of the species which can be of importance during a risk assessment (for example, information on reproductive biology, the possibility of crosses, and ecology). In regard to intra- and interspecific crosses, emphasis has been given…

Rice is grown worldwide and is a staple food for about a half of the world’s population. It is a nutritious grain crop which contains carbohydrates, proteins, lipids, minerals, etc. Rice straw is an important animal feed in many countries. Attachments: Biology_of_Rice
Read MoreConsensus Document on the Biology of Glycine max (L.) Merr. (Soybean)
Cultivated soybean, Glycine max (L.) Merr., is a diploidized tetraploid (2n=40), in the family Leguminosae, the subfamily Papilionoideae, the tribe Phaseoleae, the genus Glycine Willd. and the subgenus Soja (Moench). It is an erect, bushy herbaceous annual that can reach a height of 1.5 metres. Three types of growth habit can be found amongst soybean cultivars: determinate, semi-determinate and indeterminate (Bernard and Weiss, 1973). Determinate…
