Genomic <i>in situ</i> hybridization (GISH) identification of the mitotic and meiotic patterns in wheat-<i>P</i>. <i>huashanica</i> disomic addition line 25-10-3.

<p>(a) Somatic chromosomes in the root tips: 2<i>n</i> = 44, i.e., 42 wheat chromosomes and two <i>P</i>. <i>huashanica</i> chromosomes with strong yellowish-green hybridization signals. (b) Chromosome behavior of pollen mother cells during metaphase I, i.e., 2<i>n</i> = 22 II, where the alien chromosome comprises one ring bivalent with a yellowish-green signal.
