| Abstract: |
Rice is economically, socially, and culturally important crop of Nepal. Landraces occupies
the significant role in Nepalese rice system. They are important rice genetic resources of the
count1y. However, they are declining day by day. Household survey and focus group
discussion was carried out in Zvadul besi area (Gorkha) d!lring Nov.-Dec. 2003. Focus
group discussion iiz Kachorwa (Bara) was also conducted during Jan. 2004. The purpose of
the study was to identify the changed diversity on rice landraces, and its cause. In case of
Kachorwa, Community Biodiversity Register (CBR), 2003 was used for our purpose. Genetic
erosion was also quantified using Guarino 's score (199 5). Though, the score for genetic
erosion is not high in Zydul besi (20), the inter-varietal diversity of rice landraces was found
decreasing. Zydul besi farmers were searching for rice varieties that have higher and stable
yield, but till now no modern varieties can compete with their landraces Aanpjhutte. No. and
area un:Jer landraces was found drastically decreased in Kachorwa since last fev.• years.
Despite of higher Guarino's score (75), In-situ conservation on agro-biodiversity project is
working effectively for consen,ation of rice landraces using different approach of
conservation. However, Kachonva farmers also start the introduction of hybrid rice.
Culturally important rice landraces were found cultivated by many households in small area
only. Since, rice landraces were most 1ieed to resource poor farmers, its replacement can be
effectively reduced by removal of its undesirable characters. Participatory Plant Breeding
(PPB) is the most important technology for sustainable conservation of Nepalese rice
landrace gene pool. Since, farmers were not aware on benefit sharing, and their right, P P B
will create their interest towards IPRs also. |
