Evaluation of sesame crosses for heterosis of yield and yield attributing traits

Abstract

The extent of standard heterosis of eleven characters of sixty hybrids of sesame developed by crossing 10 lines and 6testers in line x tester fashion were evaluated during Rabi, 2007-08, 2008-09 at College Farm, College of Agriculture,ANGRAU, Hyderabad, India. The analysis of variance (line x tester) revealed significant differences among genotypesfor all the characters studied. The line x tester interactions contributed up to 79.55 per cent for capsule length followedby number of seeds per capsule (77.98%), seed yield per plant (77.15%) and number of effective primaries per plantexpressed in per cent(75.75%). The highest percentage of average heterosis was observed for seed yield per plant andnumber of effective primaries per plant. Five crosses viz., PKDS-62 x IS 562 B , SI7818 x SI-3171, KKS-98049 X SI-3171, KKS-98049 x KMR-78, CST 2001-5 x TKG-22 were identified as potential hybrids with high standard heterosisfor seed yield over better yielding commercial hybrid check Swetha til. Testing of these hybrids in all India coordinatedtrials across different states of the country may result in identification of better hybrids in the near future for commercialexploitation (2) (PDF) Evaluation of sesame crosses for heterosis of yield and yield attributing traits.
