[CdCl2-induced morphogenetic variation of Triticum aestivum cultivars]
Abstract:
The effect cadmium chloride on released local cultivars of soft spring wheat (Triticum aestivum) has been studied under laboratory and field conditions in order to widen the variation spectrum of this plant. It has been found that treatment of grains with a 0.01% aqueous solution of CdCl2 induces the appearance of tall, strong plants with productive bushiness in the M1 generation that are characterized by various morphological changes: elongated ears, scales, and grains; increased number of grains per ear and mass of 1000 grains; anthocyan pigmentation of the stem and leaf axil; etc. Study of meiosis showed chromosome aggregation, displacement of the mitotic spindle of the metaphase plate, and empty (sterile) cells in anaphases (AI and AII). The altered characters of M1 plants are preserved in the M2-M4 generations.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal chance to...
