Abstract

The study was to determine the growth and yield and to perform ear to row selection in a plant breeding program to develop some open-pollinated corn varieties for high production. The seeds was originated from 15 corn-cob of full-sib family of 8 accessions of UNSRI-J1 to UNSRI-J8. Observations were made on several growth and yield variables. Data analysis was carried out by using the T-Test at α = 0.05. Results of this research indicated that corn accession of UNSRI-J1 showed the best growth and yield with plant height of 183.52 cm, 50% male flowering at 45 DAP, and potential production of 4.45 ton dry seed/ha, followed by accessions of UNSRI-J2 and UNSRI-J3, which were only significantly different on diameter and weight of the cob. Ear to row selection in preparation for Recurrent Genotypic Selection, by using dry-weigh seeds, come up with 6-9 selected parents for accessions of UNSRI-J1s/d UNSRI-J7, with prediction of yield potential of 1.39-4.70 ton dry seeds/ha. Furthermore, selection by using variables of cob length and dry-weight seeds in preparation for Recurrent Phenotypic Selection, resulted in 6-22 cobs of accessions of UNSRI-J1, UNSRI-J2, UNSRI-J3, UNSRI-J4, UNSRI-J5, dan UNSRI-J7, with prediction of yield potential ranged 2.12 – 6.31 ton dry seeds/ha.
