2. PROGRESS IN HR DEV. IN INDONESIA 2.1. History of HR Development • HR research started in 1983. • Until 1990s, HR research was not successfull as expected difficulties in obtaining stable CMS lines with high outcrossing rates (≥ 25%), and adapted to Indonesian environment. • RYT showed that the highest yield wasalways obtained by hybrid rice combinations. • Finally resulted in several hybrid combinations consistently showed higher yield than check varieties IR58025A/IR53942 and IR58025A/BR827-35 which were then released in 2002 as Maro and Rokan.
Since 2001, HR research has beenintensified collaboration between IAARD with IRRI, FAO, and others. • ICRR had come out with several promising hybrid combinations and new CMS, maintainer, and restorer lines. • In 2004 Hipa3, Hipa4, • In 2007 Hipa5 Ceva and Hipa6 Jete. • The superiority of those new hybrids compared to Maro and Rokan were their degree of resistance to major pest and diseases, and one of them was aromatic. • In 2009 Hipa7 and Hipa8 • In 2010 Hipa9, Hipa10, Hipa11 • In 2011 Hipa12 SBU, Hipa13, Hipa14 SBU, Hipa Jatim1, Hipa Jatim2, Hipa Jatim3

Present and future research program • Improving the hybrid and parental lines resistance to major pest and diseases • enhancing the level of heterosis through indica x tropical japonica hybrids • Improving grain quality of hybrids by appropriate breeding and selection of parental lines • Improving cultivation and pest management strategies for consistent performance of hybrids
Hybrid rice research priorities at ICRR • Increase and stabilize yields of seed production • Enhance yield heterosis in both dry and wet seasons to >20% • Improve hybrid rice grain quality • Reduce chalk • Increase head rice recovery • Improve resistance to biotic stresses • Hybrid rice for unfavorable environments

(iv). HR SEED SUPPLY AND TRADE Planted area and seed supply during the period of 2005-2010
HYBRID RICE SEED PRODUCER S MEETING IN 14 th May 2010 • The F1 hybrid rice demand prioritized fullfiled from Domestic production • Provision plan of Hybrid rice seed production for 2010 – 2014 : 3. Seed import of F1 hybrid rice seed are restricted until 3 years after it released. 4. Since September 2011 , max 2 years after hybrid rice released Imported of F1 hybrid rice seed restricted .
(vi) Impact of HR adoption • Crop area of Hybrid rice in Indonesia curently : 600,000 Ha • Increase yield because of hybrid around 600 – 1000 kg/Ha, resulting production increase 360,000to 600,000 ton grain • Rice grain price is Rp. 4,000/kg, resulting the increase of farmer’s profit appoximately from 120million to 200 million US$ per crop • If there are 2 crops per year, total increasing of farmer’s profit approximately 240 to 400 million US$ per year • If milling recovery will reach 50%, then the increasing of rice per year will be 180,000 to 300,000ton/crop or 360,000 to 600,000ton per year.
3. CONSTRAINTS AND GAPS IN HR DEVELOIPMENT 3.1. Technology constraints : synchronization of flowering 3.2. Social and economic constraint : (a). Farmer habit to used seed from previous crop, (b). Expensive seed price, (c). Low price of hybrid paddy 3.3. Capability constraint : Limited seed grower (complicated procedure) 3.4. Environment constraints : (a). Fluctuative temperature and rain fall espesially for seed production, (b). Pest and desease, espesially BPH, BLB, Blast, SB 3.5. Policy constraints : Program/policy often change, there’s no long term program

4. Lesson Learn • Global climate change was boosted the pest and diseases outbreak during last several years, then improve the HR resistant to pest and diseases to be important. • Arable land reduction due to purpose sifting in Indonesia was reach 110.000 Ha per year, Therefore developing new HR with high yield potential with good rice quality will be important • The potency of HR seed production are still low (0.5 – 1.5 t/ha). Its cause the price of HR seed was very expensive. Simplicity of seed production of new HR combination was important • Elaborate of HR dissemination across institution was identified as a important way to encourage the HR adoption
5. Opportunity for HR Development • Easy to develop indica-restorer lines and IAARD was develop several indica-CMS lines • Indonesia has many of javanicagermplasm that potencial to be converted into restorer and cytoplasmic male sterility lines • high potency to develop indica/javanica HR combination to improve the yield’s heterosis • The high population increase in Indonesia (2,39 per year?) and land reduction were drive the HR tech development • Positive support from government and private companies will boost the HR’s adoption rapidity (ICM-FS, seed subsidy)
6. KEY STRATEGIES AND POLICY OPTIONS TO PROMOTE HR DEVELOPMENT IN INDONESIA TO 2020 AND 2030 • Public-private sector partnership developed on hybrid seed production to accelerate the adoption of HR tech and some companies initiated to produce seed of public hybrids. • Breeding to develop hybrid rice resistant to BPH, BLB, and RTV has high priority in the national rice research program and some promising hybrids were obtained. • Breed mat including new developed parental lines & genetic source for desirable characters from IRRI and others are still needed. • The gov of Ind supports not only the research & dev but also the dissemination and adoption of hybrid rice technology.
