Assessment of Variability in Sugarcane Genotypes Based on Morphological Traits (original) (raw)

This study was undertaken at the experimental fields of SCRI, Mardan, Khyber Pakhtunkhwa-Pakistan during the spring cropping season of 2010-11. Sixteen sugarcane genotypes i.e., MS91CP272, MS94CP15, MS91CP238, MS92CP979, MS99HO391, S97CP288, MS99HO317, RS97N45, MS99HO388, MS99HO675, MS99HO93, S96SP1215, Hoth127, CP89831, Mardan 93 and CP77400 were used in this study. These genotypes represented diverse collection from sugarcane breeding stations including USA, South Africa and Brazil. The aim of the study was to characterize these genotypes on the basis of morphological traits including cane height, cane color, hardness, thickness, leaf color, attitude, leaf shape, ligule size, dewlap color, pith, bud shape, lodging, streaks, wax, tillering, pubescence, growth, maturity, tops and trash. The cluster analysis divided 16 sugarcane genotypes into four different clusters at Euclidean distance of 4.99. Pair wise Euclidean distance ranged from 2.30 to 7.43. The highest Euclidean distance w...
