| Abstract: |
Rice (Oryza sativa LJ is the main cereal grain and an important staple food crop ofNepal. It
is grown in a wide range of agro ecological regions where landraces and improved varieties
coexist. High level of diversity in the form of landraces and their wild relatives indicates the
richness . in the genetic variation. A total of 13 7 accessio.zs of rice landraces were
characterized for ·morpho agronomic traits using IPGRIJIRRJ descriptors at Khumaltar
during 200212003. Eight quantitative and six qualitative traits were recorded to assess the
diversity in agro morphological traits among these landraces. A range of variability was
observed among the accessions of rice landraces. Altogether 3107, 1728 and 2030
accessions of Nepalese rice germplasms are conserved in the gene bank of ABD, Khumatar,
IRRI and NIAR, respectively. Six varieties of rice were developed and released for
commercial cultivation using local landraces. The examined /andraces of rice have high
variability for agro morphological traits, which can be used in crop improvement
programme. Characterization, conservation and utilization of such valuable resources would
provide a sustainable basis for rice improvement in future. |
