| Cultivated rice (Oryza sativa L.) is self-pollinating, with flowering traits that exclude crosspollination. Hybrid rice seed production is therefore limited by low outcrossing rate between parental lines. To improve outcrossing ability in cultivated rice, common wild rice (O. rufipogon Griff.) was used as a source for outcrossing traits and backcrossed to Suphanburi 1 (SPR1) cultivated rice (BC2). In this study, F5 progenies of the backcross (BC2F5) were grown and evaluated for flowering traits in comparison with SPR1 parent. At flowering, florets were collected to measure the length of anthers and pistil. The anthers of SPR1 averaged 2.32 mm and pistil 1.50 mm, in length. The F5 population ranged 2.40 to 3.93 mm in anther length (3% to 170% of SPR1) and... |

| SSSIVb gene, which is the group of Soluble Starch Synthase enzyme, concerns to synthesis amylopectin in the seed of rice. In this research, we will examine the process of mRNA splicing intron 6, 7, 8 and 9 of SSSIVb gene and observe the expression of gene in development of seed at 5, 10 and 15 days after flowering (DAF) in 5 varieties of the rice which are RD10, Chai Nat 1, Niew Phrae 1, San-pah-tawng 1 and Suphan Buri 60. All of those varieties have different quality of cooking. From the experimental, we found that Chai Nat 1 had splicing in 5 DAF rice seeds but no expression in 10 and 15 DAF rice seeds. In Suphan Buri 60 had splicing in 10 DAF rice seeds but no expression in 5 and 15 DAF rice seeds. And RD 10, Niew Phrae 1, San Pah Tawng 1 had splicing... |

| Root anatomical traits, which include cortical area, aerenchyma area, and xylem features, influence the absorption and translocation of water and nutrients, oxygen transport and the mechanical strength of the root system. While a number of studies have shown promising functional benefits of anatomical root traits in conferring resource acquisition efficiency, very little is known about the genetic mechanisms underlying natural phenotypic variation of these traits. In this study, we evaluated 336 Oryza sativa accessions selected from the rice diversity panel for 4 root anatomical traits including, root cross-section area, aerenchyma, and xylem features in well-controlled greenhouse environment. Considerable phenotypic variation was observed in all root... |
