Kesan penggabungan germplasma tagung dari CIMMYT (Rattray Arnold) dengan germplasma tagung tempatan (Jagung Kumpit)

The objective of this study was to determine the effect of combining the white dent corn germplasm from CIMMYT with the local corn germplasm. The determination was done by comparing the morpho-agronomic characters between the progenies of the cross and the parents. The study was initiated by making the cross between Rattray Arnold, the population from CIMMYT with 'Jagung Kumpit", the local population. Subsequently, seeds of the cross, Rattray Arnold and Jagung Kumpit, were planted on the experimental plot and observations were made on the morpho-agronomic characters of each plant in every population. The statistical analyses of the observed data showed that the progenies of the cross reached the stage of tasselling, silking and maturity earlier than the parents. The progenies of the cross had lower means in plant height and total dry weight. than Rattray Arnold but did not differ significantly from 'Jagung Kumpit". With respect to yielding ability, the progenies had significantly greater means of ear weight and ear length than the means compared to those of 'Jagung Kumpit" but they did not differ from Rattray Arnold.
