Buckwheat is the major export food commodity of Nepal. It has food as well as medicinal
value too. Buckwheat is found cultivated from Inner Terai to high hill region of Nepal.
Therefore, Nepalese buckwheat should have a lot of variability that is adapted with
different niches. Fifty one common buckwheat and 36 tartaiy buckwheat accessions from
different parts of the country were evaluated for different agro-morphological traits during
spring season of 2010 and 2011 at Khumaltar, Lalitpur. The plot size was 1 m2 for each
entry. IR-13 for common buckwheat and Kabre local for tartaiy buckwheat was used as
standard check. A lot of variation was observed on 24 different characters. Days to 50%
flowering, no. of flower/cyme, no. of cyme/plant, seed no./cyme, 1000 grain weight and
seed length varies from 31-44, 17-38, 12-107,2.34-51.67, 15-30.52 g and 5.58-7.38 mm in
common buckwheat, and 54-70 days, 12-25.67, 13.34-81,2.67-46, 10.34-21.76 g and 3.89-
5.60 mm in tartary buckwheat respectively. Similarly, a lot of variation was found on
flower morphology, degree of determination, lodging, seed shape, leaf blade shape, and
plant height and branch no. too. The color of flower, leaf, leaf margin, stem, petiole and
seed were also found varied within buckwheat type also. Chlorophyll content on the final
completely opened leaf was found decreasing slowly till flowering, however, it was found
drastically depleted at the time of seed maturity in both type of the buckwheat. This type of
the variation observed in common buckwheat and tartary buckwheat will be useful for
buckwheat varietal development program in Nepal.
