Abstract

Non-tidal swamp is one of suboptimal land available to increase rice production in Indonesia. The problems is stagnant flooding during vegetative growth phase of the crop. Therefore, it is important to have rice varieties that tolerant flooding. Crossing and selection have been conducted to obtaine BC2F2 genotype from local swamp rice varieties, i.e. Siam, Pegagan and Pelita Rampak. This research was aimed at knowing the growth and production of several genotypes BC2F2 and their parental varieties, Siam, Pegagan and Pelita Rampak. The research was conducted in non-tidal swamp in Village Sako, sub-district Rambutan, District Banyuasin, South Sumatra from October 2017 to March 2018. Rice genotypes have been used BC2F2 Siam, BC2F2 Pegagan, and BC2F2 Pelita Rampak, and their parental varieties i.e. Siam, Pegagan, and Pelita Rampak. The results showed that genotype BC2F2 had vegetative and generative characters different from those of Siam, Pegagan, and Pelita Rampak. The production of the tested rice varieties was high, ranged from 4.52 to 7.95 tonnes per hectare. The best of each genotypes planted in the first season were SM 2, PGG 4, and PLR 3. While the best BC2F2 of each genotypes planted in the second season were SM 2, PGG 3, and PLR 3.

Abstract

ABSTRACTOne of efforts to increase rice production at swamp area which is frequently flooded is the use of submergence tolerant rice varieties. The objectives of this research was to improve plant tolerance after submergence stress for 14 days in BC1F1 of crosses between local superior varieties and Sub1 gen donor (FR13A). The studies were carried out in two stages: 1) Crossing local superior varieties, i.e., Pegagan (Pgn), Siam (Sm), Payak Selimbuk (Pys), dan Pelita Rampak (Plr) to submergence tolerant variety FR13A; and 2) submergence tolerance evaluation of the progeny. The first study was conducted at green house of Graduate Study Sriwijaya University, Palembang. The second study was carried out at field experiment of Central Research and Development of Agricultural Biotechnology and Genetic Resources in Bogor. All studies were conducted from March 2011 until March 2013. The first study was the introgression of Sub1 gene into local genotypes Payak Selimbuk, Pegagan, Siam and Pelita Rampak from FR13A. The second study was evaluation of BC1F1 plant performance after submergence treatment for 14 days. The results showed that introgression of Sub1 gene into local varieties improved submergence tolerance as indicated by higher percentage of survived plants, lower decrease of plant dry weight, and lower decrease of grain weight per panicle compared to parents.Keywords: Sub1 gene, local swamp rice, submergence tolerant
