Uniformity Test on Generation F4, Candidates for High-Yielding Composite Corn Varieties

Abstract

Composite corn is a very promising alternative for farmers because it can be planted repeatedly and farmers can produce seeds for their own needs, although in general, the production of [local] corn seeds is lower than that of hybrid corn seeds. The purpose of this study was to produce a new composite corn variety that has a high yield potential and is adaptive to the agro-climatic conditions in West Sumatera. The study was conducted using the mass selection method in the F4 generation to test the uniformity. Based on the results of the study, it was found that the F4 population of composite corn candidates that were medium maturing and uniform had high criteria but still had wide diversity, and had high seed yields, which were even almost equivalent to those of some hybrid corns, although some characters of yield components still lack wide diversity. From the results of this study, it has been obtained candidate for high-yielding composite corn varieties that are adaptive to the agro-climatic conditions in West Sumatera.
