Heterosis for seed yield and its contributing attributes in sesame (Sesamum indicum L.)
Author(s): RS Raikwar
Abstract: A study was conducted in Sesame to estimate the magnitude of heterosis for yield and its nine yield components. 28 F1 hybrids generated by half diallel crosses of eight pure diverse parent and these F1s along with 8 parents were evaluated in a randomized block design with three replication at JNKVV, College of Agriculture Tikamgarh (MP) Appreciable heterosis was found over mid, better and standard parent for all the traits studied in desirable direction. In order of merit F1 hybrids TKG-22 x SI-205-61(118.9%), TKG-22 x RMT-187(109.8%), SI-205-1 x EC-269 (95.6%), ES-230 x SI-205-61(86.2%), ES-230 x SI-205-61(75.8%), SI-1147 x EC-269 (63.2%), RMT-187 x SI-205-61(55.2%) and SI-983 x SI-1147(42.5%) were observed significant heterosis over mid parent while the maximum heterobeltiosis (better parent heterosis) for mean seed yield per plant (g) was exhibited by the hybrid RMT-187 x SI-205-61(108.2%) followed by ES-230 x SI-983(98.9%), ES-230 x SI-205-61(82.9%), SI-983 x SI-205-61(75.4%), TKG-22 x SI-205-1(63.5%), RMT-187 x SI-205-61(46.2%), TKG-22 x RMT-187(31.8%) and RMT-187 x SI-1147(28.6%). In case of standard heterosis, significant and positive heterosis over standard check TKG-22 for mean seed yield per plant(g) was observed in hybrid TKG-22 x SI-205-1(65.3%) followed by RMT-187 x SI-205-1(86.8%), TKG-22 x SI-983(78.9%), RMT-187 x SI-1147(62.6%), SI-205-1 x EC-269 (53.2%), SI-983 x SI-1147(38.5%), SI-205-61 x SI-1147(28.5%) and SI-205-1 x EC-269 (22.4%). The present study reveals good scope for isolation of pure lines from the progenies of heterotic F1s as well as commercial exploitation of heterosis in Sesame.
