| Abstract: |
Mango is one of the important tropical fruits of Nepal ami occurs as a domesticated or ll'ild
entity in the complex of biotic community of the ecosystem. Wide ecological variation and
diverse needs of multi-ethnic comm1mities has enriched the country with genetic 1vealth of
diverse mango varieties and land races. The tropical plain, river gorge areas and sub-tropical
valleys are the regions that are rich in mango diversity. As a result, the global project on
"Strengthening scientific basis of in-situ consen•ation of agricultural biodiversity on-farm,
Nepal componellt" identified mango as a mandatol)' crop and under the project,
ecogeographic sun•ey and genetic di1•ersity was carried to measure the extent of diversity.
Siraha, Saptari, Dhading, Kavre, Parbat. Baglw1g and Dadeldlwra, the districts representing
the Terai and mid-hill ecosystems ll'ere surreyed for mango diversity. Fruit samples of 216
mango trees collected in ecogeographic sun•ey were evaluated for nineteen nwrplwlogical
characters of fruit to understand the genetic relationships. A mnge of \'(/riation e.risted in
varietalfrmit of mango with dijferellf shapes, co/ow; sizes,j7al'fmr (aroma) and taste u·ith 25-
47 coefficiellts of variation and 0.59-0.87 Shannon Weaver index. Principal compm1e11t
analysis of qualitative traits and quallfitative traits of fruits sholl'ed the existence of a
collfinuum diversity of mango in Ne1}(ll with no ecogeograpflic differentiation and qualiwtive
traits were of importance in determining tile groupings and relationships rif mcmgo \'Orieties
under study. The ecogeographic survey findings and genetic di1•ersity results were discussed
relative to the efficient utilization and c:onsen•ation. |
