ABSTRACT
The experimental material comprised of 10 most diverse parents selected on the basis of molecular characterization from the available germplasm and 45 hybrids were generated through 10 x 10 diallel mating design. Observations were recorded for major yield attributing traits.Significant interaction between combining ability effects were observed for all the traits. Four parental lines viz. JLM 7, JML 22, VL 101123 and VL 1031 were the best general combiners whereas, crosses JLM 22 x VL 101123, JLM 22 x VL 1031, JLM 7 x VL 101123, JLM 7 x CML 472, VL 101123 x VL 1031 and JLM 2 x VL 101123 revealed positive significant desirable sca, heterobeltosis and standard heterosis for seed yield per plant, biological yield per plant, harvest index, yield kg per ha, 1000 kernel weight, ear height, number of rows/ear, ear weight, stem girth and cob diameter. These crosses might be useful for future breeding programme.
Key words :
