The experiment was conducted in Randomized Block Design (RBD) with three replications at Potato Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa during rabi 2017-18. The crop was harvested at 90 days after planting. The analysis of variance revealed that mean sum of squares due to genotypes were found highly significant for all the traits. This is proved that the existence of tremendous variability in the experimental material for different traits. However, from tuber yield point of view, MS/9-2196, J/7-37, K. Ganga and K. Anand were elite genotypes based on per se performance. The genotypes, K. Lauvkar, K. Sindhuri and DSP-7 exhibited low physiological weight loss, while genotypes, K. Surya, MS/12-655 and K. Ganga had low loss due to rottage on weight basis. Thus, these genotypes may be considered as good for storage ability at room temperature storage condition. The high heritability along with high genetic advance in plant height, leaf area, fresh weight of tops per plant, number of tuber per plant, tuber yield per plant, average tuber weight, physiological weight loss, loss due to rottage on weight basis, loss due to rottage on number basis and total weight loss, suggested that genotypic variation for the characters is probably attributed to high additive genetic effect and selection would be rewarding based on phenotypic performance.

Maize (Zea mays L.) is one of the emerging crops having its position in top three cereal crops throughout the world in area and production. In this study, six lines and five testers were crossed in Line × Tester mating design to produce 30 single cross hybrids. The hybrids, their parents along with standard check GAYMH-1 were evaluated in Randomized Block Design, with three replications for yield and attributing traits. The results indicated non-additive gene action found to be predominant for inheritance of flowering traits while, kernel yield, cob yield, cob girth and cob length showed solely non-additive gene actions. Among the parents, BLD-250, BLD-221, BLD-210 and BLD-107 reported as best combiners for yield and attributing traits. The hybrids, Z 488-4 × VL-1032 and BLD-250 × BLD-46 reported good specific combining ability, higher magnitude of heterobeltiosis and standard heterosis for kernel yield per plant. Whereas, the cross combination, WNC 18242 × VL-1032 reported desirable SCA and heterobeltiosis for flowering and maturity traits. The cross
