AB  - The genetic distance analysis for selection of suitable parents has been 
      established and effectively used in many crops; however, there is dearth of 
      conclusive report of relationship of genetic distance analysis with heterosis in 
      sesame. In the present study, an attempt was made to estimate the associations of 
      genetic distances using SSR (GDSSR), seed-storage protein profiling (GDSDS) and 
      agro-morphological traits (GDMOR) with hybrid performance. Seven parents were 
      selected from 60 exotic and Indian genotypes based on genetic distance from 
      clustering pattern based on SSR, seed-storage protein, morphological traits and 
      per se performance. For combining ability analysis, 7 parents and 21 crosses 
      generated from 7 x 7 half diallel evaluated at two environments in a replicated 
      field trial during pre-kharif season of 2013. Compared with the average parents 
      yield (12.57 g plant(-1)), eight hybrids had a significant (P < 0.01) yield 
      advantage across environments, with averages of 26.94 and 29.99% for 
      better-parent heterosis (BPH) and mid-parent heterosis (MPH), respectively, 
      across environments. Highly significant positive correlation was observed between 
      specific combining ability (SCA) and per se performance (0.97), while positive 
      non-significant correlation of BPH with GDSSR (0.048), and non-significant 
      negative correlations with GDMOR (- 0.01) and GDSDS (- 0.256) were observed. The 
      linear regressions of SCA on MPH, BPH and per se performance of F(1)s were 
      significant with R(2) value of 0.88, 0.84 and 0.95 respectively. The present 
      findings revealed a weak association of GDSSR with F(1)'s performance; however, 
      SCA has appeared as an important factor in the determination of heterosis and per 
      se performance of the hybrids. The present findings also indicated that parental 
      divergence in the intermediate group would likely produce high heterotic crosses 
      in sesame.
