Abstract
Research on hybrid rice in Indonesia began in 1983 with the aim of exploring the prospects and constraints of this technology. Until 2019 the Indonesian government through Indonesia Agricultural Agencies Research and Development has released 21 hybrid rice varieties. 42 hybrid rice genotypes and one check variety namely Hipa 18 were tested during the season of 2014 in Sukamandi Experimental Station. Randomized complete block design (RCBD) with three replications was used in each season. The results showed that variation due to genotype were significant for all traits except panicle length. Genotype by season (GXS) interactions cause differences in productivity. Twenty one hybrid rice genotypes were selected on productivity and selection index based on contributed traits of yield i.e tiller number, number of filled grain per panicle, 1000-grain weight, and productivity according to their relative weight. Those selected hybrids were HRDC 1440, HRDC 1415, HRDC 1404, HRDC 1407, HRDC 1431, HRDC 1421, HRDC 1434, HRDC 1438, HRDC 1423, HRDC 1414, HRDC 1426, HRDC 1429, HRDC 1443, HRDC 1441, HRDC 1406, HRDC 1408, HRDC 1446, HRDC 1422, HRDC 1445, HRDC 1417 and HRDC 1419. The productivity range of those hybrids were 6.1 – 10.2 ton ha-1. The selected hybrid rice genotypes can be evaluated further in advance yield trials.
