Partial diallel analysis of agronomic characters in rice (Oryza sativa L.) Genet. Mol. Biol.
Torres,Edgar Alonso; Geraldi,Isaias O..
Rice (Oryza sativa L.) breeding seeking to combine high productivity and cold tolerance for the temperate Latin America region is an important challenge. We estimated some useful parameters which can be used to investigate the genetic control of agronomic characters in crosses combining cold tolerance and productivity. A partial diallel design was used in crosses between six tropical indica rice cold susceptible genotypes (group 1) and seven japonica or indica/japonica cold tolerant rice genotypes (group 2). Parents and crosses were evaluated for agronomic characters under field conditions in two different experiments in 2005. The results showed significant mid-parent heterosis for all characters (plant height, tiller number, days to 50% flowering, panicle...

Mapping of quantitative trait loci for thermosensitive genic male sterility in indica rice PAB
Alcochete,Antonio Alberto Neves de; Rangel,Paulo Hideo Nakano; Ferreira,Marcio Elias.
The objective of this work was to select and use microsatellite markers, to map genomic regions associated with the genetic control of thermosensitive genic male sterility (TGMS) in rice. An F2 population, derived from the cross between fertile and TGMS indica lines, was used to construct a microsatellite-based genetic map of rice. The TGMS phenotype showed a continuous variation in the segregant population. A low level of segregation distortion was detected in the F2 (14.65%), whose cause was found to be zygotic selection. There was no evidence suggesting a cause-effect relationship between zygotic selection and the control of TGMS in this cross. A linkage map comprising 1,213.3 cM was constructed based on the segregation data of the F2 population....

HYBRID RICE AND ITS IMPACT ON FOOD SECURITY AND THE PATTERN OF GLOBAL PRODUCTION AND TRADE AgEcon
Durand-Morat, Alvaro; Wailes, Eric J.; Chavez, Eddie C..
The hybrid rice technology is one of the many ways in which productivity of scarce resources devoted to rice production could be enhanced, with the consequent alleviation of food insecurity. The findings of this study show that the hybrid rice technology has so far made some sizable contributions to per-capita availability of rice in adopting countries with marginal spillover effects to other regions. However, at forecasted population growths, a massive intensification of adoption would be needed to maintain per-capita availability of rice at baseline levels. But even with adoption rates climbing significantly, much higher equilibrium prices are expected, which will represent a challenge for the hungry in many parts of the world. While hybrid rice has the...

การวิเคราะห์ข้อมูลการถอดรหัส ที่ส่งผลต่อการแสดงออกของยีนที่แตกต่างกันในช่อดอกจากจีโนมข้าวลูกผสมและพันธุ์พ่อแม่ Thai Agricultural
Kulchana Ketsuwan.
Next Generation Sequencing (NGS): SOLiD System Sequencing Platform was applied to investigate the whole transcriptome of two hybrids (PTT06001H; H1 and PTT06008H: H2), two paternal lines (CK81; P1 and CK120; P2), and maternal line (IR79156; M). The data sets were aligned against the reference, precisely, the total numbers of the individual rice panicles sample aligned with Nipponbare ranking from the highest were as follows, P2 (9,747,077 reads), H1 (7,386,061 reads) , P1 (5,361,077 reads) , H2 (5,196,982 reads), and M (2,244,306 reads), respectively. The differentially expressed genes (DEGs) were identified and found that 2902, 1604, 3168, 3068, 1171, and 3031 genes were up-regulated (> 2 fold) between M vs. H1, P1 vs. H1, M vs.P1, M vs. H2, P2 vs. H2,...

การพัฒนาสายพันธุ์เพศผู้เป็นหมันของข้าวโดยวิธีการผสมกลับและทดสอบสมรรถนะการผสม Thai Agricultural
Pachara Saengsawong; Supaporn Junbuathong; Piyavadee Charoenwattana.
In three-line hybrid rice system, development of parental lines by backcrossing and early generation testing for combining ability is a method used for developing CMS lines (A line) and restorer lines (R line) simultaneously. In this study F3 progenies from 15 crosses of maintainers (B line) were backcrossed to their respective A lines, and 6 crosses and 46 isogenic lines produced. Completely sterile backcross progenies were found in 3 crosses, i.e., IR79156A//IR79156B/CNT1, IR80156A//IR80156B/IR46R and IR80156A//IR80156B/SPR1. Concurrently three new CMS lines, PTT08001A, PTT08002A and PTT08003A were developed. They were then crossed with 5 testers or restorer lines, i.e., RD31, SPR1, CK81, CK120 and CK168. The resulting 15 crosses of F1 hybrid were...

ข้าวลูกผสม: งานวิจัยที่ยาวนานสำหรับทางเลือกการผลิตข้าว Thai Agricultural
Boriboon Somrith.
Hybrid rice is one of technological means to increase rice production. Research and development on hybrid rice has been conducted for more than 40 years. This article reviews the hybrid rice impacts on increasing rice production through hybrid rice technology in China, Vietnam and India. Status of hybrid rice research in Thailand from the past to present was summarized. Furthermore, consideration, especially on production cost and benefit in adoption of hybrid rice technology at farmer level was also proposed.

การพัฒนาสายพันธุ์เรณูเป็นหมันโดยวิธีการผสมกลับ Thai Agricultural
Bang-on Thammasamisorn.
Development of new CMS lines by backcrossing was conducted at Suphan Buri Rice Research Center during 2005-2011. The objective was to develop Thai elite breeding lines to be better varieties of CMS lines adapted to the environment in Thailand. The new CMS lines will be used for research project on hybrid rice production. CMS lines from IRRI were used as donor in repeated backcrossing of 6-7 generations to the recurrent parent, Thai elite breeding line. After seven generations of repeated backcrossing two new CMS lines, SPR06186A (IR58025A/7*SPR98015-59-1-2-2-2) and SPR06189A (IR73328A/7*SPR98015-59-1-2-2-2), were developed. These two lines have one hundred percent of pollen sterility and similar agronomic traits to the recurrent parent. SPR06186A has a...

ประเมินมูลค่าคุณลักษณะประจำพันธุ์ของข้าวลูกผสมในประเทศไทย Thai Agricultural
Suthipol Saeli; Orachos Napasintuwong Artachinda.
On September 27, 2011, the Rice Department of Thailand certified first two hybrid rice varieties. However, the information about trait preferences remains unanswered. The objective of this study is to derive the trait valuation of hybrid rice in Thailand using a choice experiment estimated by a mixed logitmodel. The survey of396 farmers reveal that resistance to brown plant hoppers has the highest value, followed byhigh yielding and height, respectively. Therefore, rice breeding for high yielding varieties in Thailand should take into account such traits in response to farmers demand.

Expression of resistance in rice hybrids to Pyricularia grisea Trop. Plant Pathol.
PRABHU,ANNE S.; GUIMARÃES,ELCIO P.; FILIPPI,MARTA C.; ARAUJO,LEILA G.; CUTRIM,VERIDIANO A..
Thirty-nine rice (Oryza sativa) hybrids and their restorers were assessed for vertical resistance to Pyricularia grisea in the rice blast nursery, and in artificial inoculation tests with two pathotypes, under controlled greenhouse conditions. The hybrids were developed from cytoplasmic genetic male sterile lines 046I and IR 58025A, derived from WA cytoplasm. In the rice blast nursery all hybrids showed susceptible reaction varying from 5 to 9. Compatible and incompatible leaf blast reactions of hybrids to two pathotypes, IC-1 and IB-45, were observed in inoculation tests. A majority of the hybrids were resistant when the restorer was resistant. However, seven of the 25 F1 hybrids exhibited susceptible reactions even when one of the parents was resistant...
