“…These results suggest that varietal differences in response to flooding treatment are not related to emergence of seedling in the field. Although varietal differences in the germination of wheat seeds have been reported (Allan et al, 1962;Sunderman, 1964;Lafond and Baker, 1986a), we did not find any significant correlation among wheat varieties with respect to field emergence (Table I). Since the number of emerged plants depended on the seed size and their harvest year (Fig.…”

“…These GA-insensitive dwarfing genes have a pleiotropic effect on plant growth, causing reduction in coleoptile length and seedling leaf area (Allan et al, 1962;Whan, 1976). In this study, both the first leaf length and coleoptile length in Huaai 01 were insensitive to exogenous GA 3 treatment (Figure 1).…”

ABSTRACT.A spontaneous dwarf mutant of wheat was found in an F 5 generation line derived from a cross between Huamai No. 9 and Een No. 1 in 1998; it was named Huaai 01. We characterized the genetic pattern of Huaai 01 and mapped the gene controlling the dwarf trait. This dwarf mutant was found insensitive to exogenous gibberellic acid treatment, based on the length of the first leaf and the coleoptile at the seedling stage, suggesting that it plays a crucial role in the gibberellin response pathway. Genetic analysis revealed that a single gene that is partially recessive controls the dwarf phenotype in Huaai 01. We named the dwarfing gene Rht-B2. Simple sequence repeats (SSR) were examined as identifying markers linked to the Rht-B2 gene in an F 2 population. We screened 904 pairs of primers and identified 5 SSR markers linked to the Rht-B2 gene. Two markers, barc1096 and xgwm495, were located on the flanking region of the Rht-B2 gene at genetic distances of 2.9 and 3.3 cM, respectively. Based on published SSR linkage data for wheat, the Rht-B2 gene was mapped to the long arm of chromosome 4B. This identification and characterization of the Rht-B2 dwarfing gene will facilitate its utilization in wheat breeding.

“…Due to this association, studies conducted in wheat on the relationselection for short culm often led to a ship between coleoptile length and culm reduction of coleoptile length and, as a length, this problem still remains largefy consequence; to a reduction' of seedling unexplored in barley. Verma et al (1972) vigor and percent emergence (Livers 1958; have found that coleoptile length in barley is Allan et al 1962;Sunderman 1964; Burleigh under the control of a polygenic system with et al 1965;Feather et al 1968; Kaufmann dominance of the alleles which increase the 1968). The possibility of selecting character: therefore an analogy seems to genotypes with short culm and long or exist to the genetic control of culm length fast-growing coleoptile has, however, been (Ceccarelli et al 1974;Lorenzetti and can.J.ptanrScr.60:6E7-693(Apr.…”
