Abstract

Crosses are among the breeding methods to obtain superior varieties. To obtain superior varieties requires information about the combining ability, heritability and genes action of lines for parental crosses. The purpose of the present study was to estimate the combining ability, heritability and the genes action of yield components of inbred corn lines in diallel crosses. The study was conducted at the Experimental Station of Agro-Technology Study Program of Agriculture Faculty, University of Trunojoyo Madura from February to July 2017. The parents used in the study were UTM 2, UTM 7, UTM 14, UTM 14, UTM 15, UTM 18, UTM 22 and UTM 31. The estimation of general combining ability (GCA), specific combining ability (SCA), heritability and the genes action was performed by using the Griffing’s method I. The experiments used the randomized complete block design (RCBD) with three replications. Results showed that the characters of 50% flowering age, harvesting age and production per hectare were affected by the role of additive and dominant genes, while the cob length, cob diameter, and weight of 100 seeds were affected by the role of the dominant genes. The UTM 2 and UTM 31 parents were the best combiners for production per hectare, UTM 7 was the best combiner for cob size. Thus, the three parents could be used to assemble varieties with a high production per hectare. The cross combinations of UTM 31 X UTM 2 and UTM 31 X UTM 22 could be directed to hybrid varieties with a high production properties and early maturity. The heritability value in the broad and narrow sense was the highest for the harvesting age character.
