Abstract/ Executive Summary:

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%).

Keywords: Genetic erosion, Conservation, Citrus

Location: Nijpat, Jaintapur, Fatehpur, Darbast, Chiknagul and Charikata at Jaintapur upazila of Sylhet district, Bangladesh

Start Date: 00-07-2013

End Date: 00-11-2013

Program Area: Knowledge Management

Commodity: Citrus

Objectives:

To know the present conservation status as well as to find the causes and extent of reduction of citrus biodiversity at Jaintapur upazila of Sylhet district, the present investigation was undertaken

Methodology:

The study was conducted in sixunions i.e., Nijpat, Jaintapur, Fatehpur, Darbast, Chiknagul and Charikata at Jaintapur upazila of Sylhet district, Bangladesh during July to November 2013. The study area was located between 24°59' and 25°11' North latitudes and in between 92°03' and 92°14' East longitudes. The climate of Jaintapur is humid subtropical with a predominantly hot and humid summer and a relatively cool winter. It is generally marked with the monsoon climatic zone, with annual average highest temperature is 23°C in August to October and average lowest temperature is 7°C in January. Nearly 80% of the annual average rainfall is 3334 mm between May and September (Wikipedia, 2013). The primary data were collected by (i) direct observation; (ii) interviewing farmers and (iii) record kept by farmers. Data were collected through farm visits in the study area and personal interviewing with a purposive sample of 60 households from a total of 27719 which is about 0.002% (BBS, 2010). The head of the households were interviewed with the use of an informal and semi-structured questionnaire. The data collected from household interviews were crosschecked with key informants and people from various levels of society. At the stage of data analysis, qualitative and quantitative analyses were carried out using Microsoft Excel and SPSS software, 2006.

Achievement/Findings:

Diseases and insect pest infestation were the most serious problems responsible for the genetic erosion of citrus species followed by lack of credit facilities, quality seed and seedling of citrus species. Some of the respondents were found more interested in growing income generating commercial citrus tree species such as Zara lebu, Ada jamir, Elachi lebu instead of other citrus species prevailing in homesteads. This may happen to be a serious threat to the biodiversity of other citrus species which traditionally conserved in homesteads in near future. Therefore, scientists, researchers and naturalists have to give priority in bio-prospecting and value addition of the other citrus species for better income generation and to conserve biodiversity of the homesteads. This can be done by providing training and/or some incentives to the owners to be more careful about conserving citrus species. Government and non-government agencies should work closely with local people to provide advisory and material support to play significant roles in creating a better future for these citrus species.
