“…KATO et al (2001) identificaram um QTL principal, localizado no braço longo do cromossomo 4AL, que pode explicar mais de 77% do efeito para dormência. No entanto, a obtenção da tolerância à germinação depende de uma interação entre os fatores ambientais e os genes envolvidos na herança de diferentes caracteres (BASSOI et al, 2006).…”

“…For example, dormancy QTLs are distributed over all five chromosomes (chr) in Arabidopsis (Arabidopsis thaliana) ( Van der Schaar et al, 1997;Alonso-Blanco et al, 2003;Clerkx et al, 2004) and 11 of the 12 chr in cultivated (Oryza sativa) (Wan et al, 1997;Lin et al, 1998;Dong et al, 2002;Miura et al, 2002), wild (O. rufipogon) (Cai and Morishima, 2000;Thomson et al, 2003), and weedy (O. sativa) (Gu et al, 2004) rice. Dormancy QTLs in barley (Oberthur et al, 1995;Li et al, 2003;Prada et al, 2004), sorghum (Lijavetzky et al, 2000), and wheat (Anderson et al, 1993;Kato et al, 2001;Mares and Mrva, 2001;Groos et al, 2002;Osa et al, 2003;Kulwal et al, 2004) have been identified to seek gene resources to impart resistance to preharvest sprouting (PHS) and to manipulate germination programs in the malting process. Additional research has been aimed at isolation of individual dormancy alleles from donor parents to determine gene effects, interactions with environmental factors, and breeding potential.…”

Seed dormancy is a key adaptive trait under polygenic control in many plants. We introduced the chromosomal regions containing the dormancy QTLs qSD1, qSD7-1, and qSD12 from an accession of weedy rice into a nondormant genetic background to examine component genetic effects and their interactions with time of afterripening (DAR). A BC 4 F 2 plant, which was heterozygous for the three loci, was selected to develop the BC 4 F 3 population. Single point analysis detected only qSD7-1 and qSD12 (R 2 ¼ 38-72%) at 10, 30, and 50 DAR in the population. However, multiple linear regression analysis detected genetic effects of the three QTLs and their trigenic epistasis, an environmental effect of DAR (E), and interactions of E with qSD12 and with the qSD1 Â qSD7-1 and qSD7-1 Â qSD12 epistases. The linear model demonstrates that QTL main effects varied with DAR, and that some epistasis or epistasis-by-DAR interactions partially counteract the main effects. The three QTLs were isolated as single Mendelian factors from the BC 4 F 3 population and estimated for component genic effects based on the BC 4 F 4 populations. Isolation improved estimation of the qSD1 effect and confirmed the major effect of qSD12. The qSD1 and qSD12 loci displayed a gene-additive effect. The qSD7-1, which was further narrowed to a chromosomal region encompassing the red pericarp color gene Rc, displayed gene additive and dominant effects. Heredity (2006) 96, 93-99.

“…Anderson et al (1993) reported several QTLs for PHS resistance on chromosome arms 1AS, 3BL, 4AL, 5DL, and 6BL. Kato et al (2001) detected a major QTL for PHS resistance on 4AL of a red wheat cultivar, and Mares and Mrva (2001) reported the same QTL, but with smaller eVect, for seed dormancy in white wheat. Several recent studies demonstrated that the major QTL on 4AL is present in both white and red wheat cultivars of diverse origins (Chen et al 2007;Lohwasser et al 2005;Mares et al 2005;Torada et al 2005).…”

“…Seed dormancy and PHS in Arabidopsis, wheat, barley, rice, and sorghum are expressed as quantitative traits that are strongly inXuenced by environments as well as interactions between genotype and environment (Alonso-Blanco et al 2003;Anderson et al 1993;Gu et al 2004;Kato et al 2001;Lijavetzky et al 2000). Red color pericarp/testa has been associated with longer seed dormancy and/or PHS resistance in crops, and red grain wheat usually has a higher level of PHS resistance than white wheat (Debeaujon et al 2000;Gfeller and Svejda 1960;Seshu and Sorrells 1986).…”

Although QTLs for PHS resistance have been identiWed on many chromosomes in diVerent studies, chromosome 4A and all long arms of group 3 chromosomes appear to be more critical for PHS resistance (Flintham and Gale 1996;Groos et al 2002;Kato et al 2001;Kulwal et al 2004;Mori et al 2005;Osa et al 2003).…”

Quantitative trait loci for resistance to pre-harvest sprouting in US hard white winter wheat Rio Blanco

et al. 2008

Pre-harvest sprouting (PHS) of wheat is a major problem that severely limits the end-use quality of Xour in many wheat-growing areas worldwide. To identify quantitative trait loci (QTLs) for PHS resistance, a population of 171 recombinant inbred lines (RILs) was developed from the cross between PHS-resistant white wheat cultivar Rio Blanco and PHS-susceptible white wheat breeding line NW97S186. The population was evaluated for PHS in three greenhouse experiments and one Weld experiment. After 1,430 pairs of simple sequence repeat (SSR) primers were screened between the two parents and two bulks, 112 polymorphic markers between two bulks were used to screen the RILs. One major QTL, QPhs.pseru-3AS, was identiWed in the distal region of chromosome 3AS and explained up to 41.0% of the total phenotypic variation in three greenhouse experiments. One minor QTL, QPhs.pseru-2B.1, was detected in the 2005 and 2006 experiments and for the means over the greenhouse experiments, and explained 5.0-6.4% of phenotypic variation. Another minor QTL, QPhs.pseru-2B.2, was detected in only one greenhouse experiment and explained 4.5% of phenotypic variation for PHS resistance. In another RIL population developed from the cross of Rio Blanco/NW97S078, QPhs.pseru-3AS was signiWcant for all three greenhouse experiments and the means over all greenhouse experiments and explained up to 58.0% of phenotypic variation. Because Rio Blanco is a popular parent used in many hard winter wheat breeding programs, SSR markers linked to the QTLs have potential for use in high-throughput marker-assisted selection of wheat cultivars with improved PHS resistance as well as Wne mapping and map-based cloning of the major QTL QPhs.pseru-3AS.
