Synthesis and introduction of adaptive open-pollinated-maize accessions may help farmers at tidal-swamp to increase income, since farmers can produce the seeds directly from their plantation.
This research utilized fields and farmers of such area located at South Sumatera, Indonesia. Evaluated plants consisted of Unsri-J1 to J8-accessions, generated from recurrent-selections of double-crossing populations between Indonesian varieties and introduced-accessions of high-quality protein maize (HQPSSS) from Purdue University, and acid-soil tolerant accession maize (SA3) from CIMMYT. Evaluation was designed as randomized complete block. Measurements were taken on five observation-plots consisted of 25 plants/plot. Statistical analysis was performed by using Analysis of Variance, followed by Fisher's protected-LSD-test.
Research indicated that most accessions showed good performance. The plant-height ranged 200 to 228 cm and anthesis-period at 44 to 46 days after-planting. The half-sib seeds production ranged from 2.20 to 2.93 t/ha and the real-yield, at farmer level, ranged 5.5 to 7.7 t/ha and the potential-yield reached 7.6 to 9.6 t/ha with protein-content ranged from 8.57 to 9.48%. This research suggested that accessions of Unsri-J6, followed by Unsri-J7, J2, J5 and J1 were promising for further development.
