Forty one wheat (Triticum
aestivum L.)genotypes were studied for days
to booting, days to heading, plant height at vegetative, plant height at
maturity, days to 50% anthesis, days to 100% anthesis, flag leaf senescence,
days to physiological maturity, peduncle length, effective tillers, spikelet’s
length, grain per spike, biomass ,harvest index, sterility percentage, thousand
grain weight and grain yield  in random complete block design at terai,
Nepal with the objective to identify superior genotypes after clustering them
based on their genetic diversity in performance. Result of multivariable analysis revealed that 41 wheat genotypes formed
four clusters. Cluster 4 and 2 had highest value of effective tiller, spike length,
grain per spike, thousand grain weight, biomass, harvest index ,grain
yield  and lowest value days to heading,
days to booting ,days to anthesis and sterility percentage. Cluster 3 had high
days to booting, days to heading, days to 50% and 100% anthesis, days to flag
leaf senescence and low in plant height at maturity, thousand grain weight
,harvest index and grain yield. Considering of multivariable
analysis and other agronomic performance wheat genotypes HD 1982 and Pitic 62 may be utilized as high
yielding genotypes in Terai condition of Nepal.
