Abstract: The present study was aimed to investigate combining ability effects for yield and yield related traits in pop corn using line × tester analysis. Eight inbred lines, three testers and resulting 24 crosses were evaluated at two locations during kharif 2016 in a complete randomized block design.. ANOVA for combing ability revealed significant mean squares of GCA and SCA for all the traits. The estimates of variance due to dominance component was higher than due to additive component for traits viz., plant height, kernel rows cob-1, grain depth, 100 grain weight, shelling percentage, grain yield plant-1 and protein content. The parent KDPI-8 was identified as best combiner for grain yield plant-1 and for most of its contributing traits followed by KDPI-4 and KDPI-6. Among the crosses, KDPI-6 × WIN POP, KDPI-8 × VL POPCORN-1 and KDPI-1 × VL POPCORN-1 exhibited highly significant and desirable SCA effects for grain yield plant-1. Therefore, these crosses could be utilized in heterosis breeding to achieve a quantum jump in maize improvement.
