Also, terpenoids, another class of volatile aromatic compounds found mostly in herbs, were identified in rice bran from purple, red, and brown rice varieties (Chumpolsri et al. Cite this article.

By using this website, you agree to our Under pest-free conditions, HM84 on average yielded almost equal to KDML105 (Table 4). When grown in its optimal environment, the physical appearance of polished grains is pearly, clear, very long and slender, with a glossy exterior. Comparing the aromatic isogenic line and RNAi in the N15 dilution experiment and inclusion of the inhibitors of enzymes in polyamine biosynthesis revealed ornithine as the initial amino acid precursor of N, and polyamine is a major biosynthetic pathway leading to 2AP accumulation (Vanavichit et al. The saline soil in this area is high in sodium and chloride content and has a sandy soil texture, low organic matter, and minimal fertility (Arunin 1984). A little expensive but we couldn’t find large bags of rice anywhere. The introduction of the Xa21 gene from the highly resistant donor line, IR1188, into KDML105 successfully generated the first Jasmine-like BLB resistant line, HM812 (Fig. Introgression of SKC1 from FL496 (IR66946-3R-196-1-1) or FL530 (IR66496-3R-230-1-1) into KDML105 was accomplished using MABC to generate KD-SKC1-FL (Fig. Marker-assisted backcrossing was comprehensively developed to add more resistance genes for diseases, insects, and abiotic stresses to KDML105 (Toojinda et al. The aromatic gene was cloned in KDML105, as an amino aldehyde dehydrogenase (AMADH) or better known as BADH2 located on chromosome 8.

Ahn SN, Bollich CN, Tanksley SD (1992) RFLP tagging of a gene for aroma in rice. Characterized by fluctuation in rainfall distribution and poor soil fertility, the lowland rainfed area produces the highest quality Jasmine rice. Grain aroma is controlled by a single recessive gene located on chromosome 8 (Singh et al. ‘Hom’ indicates the aroma and ‘Mali’ points to the texture and color of each grain. A bit disappointed as no scent of jasmine, Reviewed in the United Kingdom on 13 May 2020. 2001), which was used to identify the QTL-controlling traits above.

The first step to break the tight linkage between the two loci was to generate a large F2 population between KDML105 (waxy b, bphQTLch6) and RHt (Waxy A, BphQTLch6), followed by rigorous MAS for the (waxy b, BphQTLch6) haplotype (Jairin et al. 2006) and JHN x IR64 (Sreewongchai et al. 2007; Tragoonrung et al. As a selection of local landrace variety found in rainfed areas, the Thai Jasmine rice showed adaptive advantages over improved irrigated rice in less fertile lowland rainfed conditions. Three QTLs for GT were mapped on chromosome 6 as the single major QTL, and the two minor QTLs were mapped on chromosome 2. Later on, all other aromatic rice genes were discovered as allelic to the AMADH. 2016), respectively. 2016). Environmental factors will always have a strong influence on the synthesis and degradation of 2AP content, resulting in quantitative variation of 2AP in rice grains. Of all rice growing countries, Thailand has the most diversified pathotypes in the world (Sreewongchai 2008; Chaipanya et al. 2010) and were used as the donor for HM83. Try again. 2002). 2005).
