Abstract:

A study was undertaken to know the extent and causes of genetic erosion of citrus species at Jaintapur upazila of Sylhet district during July to November 2013. A total number of 15 citrus species were recorded from the studied homestead areas. Sorbati lebu (Citrus limmetta) and Deshi lebu (Citrus limon) were identified as endangered while Kolombo lebu and Pati lebu (Citrus limon) as critically endangered species. Kot lebu, Sulang lebu and Tuna lebu were identified as extinct from the study area. On the other hand, Zara lebu (Citrus medica), Ada jamir (Citrus assamensis), Kata jamir (Citrus jambhiri), Kurun jamir (Citrus aurantium), Elachi lebu (Citrus limon), Kagzi lebu (Citrus aurantifollia) and Komola lebu (Citrus sinensis) were found in safe condition as they were grown commonly in most homesteads of the study area. Diseases and insect pest infestation were the most serious problems responsible for the genetic erosion of citrus species followed by lack of credit facilities, and quality seed and seedling. In the study area farmers’ perceived most importance for homestead citrus species conservation was related to fruit and food (83%) followed by subsistence family income (49%) and soil erosion control (32%).
