Aegilops biuncialis

Characterization of a new wheat-Aegilops biuncialis addition line conferring quality-associated HMW glutenin subunits

J. P. Zhou, Yao, C. H., Yang, E. N., Yin, M. Q., Liu, C., and Ren, Z. L., Characterization of a new wheat-Aegilops biuncialis addition line conferring quality-associated HMW glutenin subunits, vol. 13, pp. 660-669, 2014.

In this study, a new disomic addition line, 12-5-2, with 44 chromosomes that was derived from BC3F2 descendants of the hybridization between Triticum aestivum cv. CN19 and Aegilops biuncialis was created and reported. 12-5-2 was immune to both powdery mildew and stripe rust and has stable fertility. Fluorescence in situ hybridization and C-banding revealed that 12-5-2 was a 1Ub disomic addition line (ADL1Ub).

Molecular cytogenetic characterization of the Aegilops biuncialis karyotype

Aegilops biuncialis can be hybridized with wheat (Triticum spp) and has been used for wheat breeding and genetic studies. The A. biuncialis karyotype (Ub Ub Mb Mb) was investigated based on three A. biuncialis accessions grown in China. Two pairs of SAT chromosomes were identified as 1Ub and 5Ub, with a karyotype formula of 2n = 4x = 28 = 14m + 10sm + 4st. Fluorescence in situ hybridization (FISH) and C-banding approaches were used to analyze the A.
