The study to know the origin of crop plants is not only subject of great academic interest but it is important also for a very practical reason. I start thinking about this topic when I travel through the Cameroon Highland old road to Tanah Rata on a day visits to Highland Vegetable production area for farm inspection. The crop scientist I believe had a hard work to know the genetic of particular crops to increase crop production and to extend the range of new environments in which important crop can be grown. Plants like rubber (Hevea brasiliensis), Oil Palm (Elaeis guineensis) and Cocoa (Theobroma cacao) are not from Malaysia but it was succesfully grown at our land and become the largest world producers for many decades. This article I would like to share my knowledge on the origin of Crop Plants base on my experience and make some reference to an old Longman Text Book with titled 'Botany of Tropical Crops' recently.
Two kinds of evidence I think will help us to determine and speculate the origin of crop plants. First and the most importance I think is a rare archaeological evidence of the remain of the primitive crops plants and of primitive agricultural communities (especially on their farming tools and the unstensils they use to prepare and cook their foods) provide the only empirical information about the time and place of very early agriculture. The history shown few remain area such as at Western Asia, Zagros mountain, Southern Turkey, Iraq, Iran, Mexico and China. This area are known as 'fertile crescent' for agriculture began some 7,000 - 9,000 years ago. The early crops such as maize, beans, cucurbits, chili peppers indicate the primitive wan long practiced agriculture for their foods supply.
I start think where is the origin of most crop plants today. Is it on the both theory above able to give us more confident. As I go through the books, the main centres of origin of crop plants delineated by Vanilaov and some of them were domesticated as as follows:-
1. CHINA :
Soybean, adzuki beans, Orange
2. THE INDIAN SUB-CONTINENT :
Rice, tea, jute, pepper, Some Phaseolus spp
3. THE INDO-MALAYSIAN SOUTH EAST ASIA :
Sugar cane, coconut, banana and some yams
4. THE NEAR AND MIDDLE-EAST :
Wheat , barley, rye, Lucerne, lentil, Chick pea
5. THE MEDITERRANEANS REGIONS:
Cabbage, Lettuce, olive, broad beans.
6. ETHIOPIAN REGION :
Sorghum, pearl millet, cowpea , Arabica coffee, finger millet
7. SOUTH AMERICA , CENTRAL AMERICA , ANDES AND SOUTH MEXICO : Maize, some cucurbits, upland cotton, sisal, chili peppers, potato, sweet potato, tomato
8. SOUTH AMERICA OF EAST ANDES MOUNTAIN :
Groundnut, cassava, cocoa, rubber and pineapple.
I hope the article provide some information for all readers. I think the crop plants established for human and animal consumption are created and studied for thousands years ago. The latest technology with scientific research able for us to ensure the crop plants is no more grown in the origin of the plants.
THANKS.
