Phenotypic markers of chromosomes are useful for determining chromosome behavior in cytogenetic studies. Transmission of an alien, telocentric addition from Agropyron tricophorum (Link) Richt. that confers purple aleurone pigment and blue seed color was evaluated in common wheat (Triticum aestivum L.). Twenty-five of 2570 seeds from bagged heads of eight ditelocentric-addition sister plants were almost white rather than blue. Seven of these 25 seeds and 4 of 336 blue seeds segregated 41.4%:58.6% blue:white. Meiotic analyses showed that all plants grown from these 11 seeds were spontaneously produced monotelocentric additions. Transmission of the alien telocentric chromosome through the egg and the pollen was estimated to be 19.5 and 14.3%, respectively, based on BC1F1 seed color. About 28% of F2 and F3 seeds were blue; of these 7.4% were ditelocentric additions. The frequency of blue seed in F2 progeny from spontaneous monotelocentric additions (41.4%) was significantly greater than that of monotelocentric additions from controlled crosses (28%). Penetrance of the blue seed color gene(s) associated with the alien telocentric chromosome was good. Misclassification of seed color for 1595 BC1F1 seeds was less than 3% based on BC1F2 progeny.Key words: Agropyron tricophorum.

Wheat Lines

The blue aleurone trait has been suggested as a useful genetic marker in wheat (Triticum aestivum L.). However, little information is available on its transmission in diverse backgrounds and on its use to identify hybrid seed. UC66049, a hexaploid spring wheat with a spontaneous translocation that included the gene for the blue aleurone trait (Ba) from Agropyron elongatum (Host) P.B. (synonymous with Elytrigia pontica (Podp.) Holub), was crossed to seven wheat cultivars to test the transmission of the trait. UC66049 was crossed to male-sterile red wheat lines to evaluate the blue aleurone trait as a marker for confirming hybridity. Ba segregated as a dominant gene that was transmitted normally through the male and female gametes. For 6 of 7 crosses with diverse pedigrees, we experienced problems with misclassification of the aleurone color in the F2 seed generation, determined by the F3 seed family data. The blue aleurone trait is a good genetic marker; however, progeny testing may be needed to confirm the F2 genotypes in some environments or genetic backgrounds. Moreover, Ba is useful in determining the amount of controlled hybridity as opposed to self-fertility and (or) outcrossing in genetic male-sterile wheat lines. The use of Ba to confirm doubled haploidy was proposed.Key words: Agropyron elongatum, seed color, genetics, Triticum aestivum, Elytrigia pontica.

Random lines of wheat (Triticum aestivum L.) developed from crosses RL 4137/Timgalen and RL 4137/Neepawa were used to study the inheritance of harvest-time dormancy, as measured by falling number values of rain-simulator treated samples, as well as its association with leaf rust resistance, awnedness and seed color. Heritability estimates for falling number were 0.74 and 0.78. Differences in seedling leaf rust resistance were due to Lr16, for awnedness due to a single gene and for seed color due to three genes. A positive association between leaf rust resistance and falling number was observed in RL 4137/Neepawa while a slight negative association was observed in RL 4137/Timgalen. In the latter cross, the red-seeded lines had a higher mean falling number than the white-seeded lines, while the awned lines had a lower mean falling number than the awnless lines.Key words: Triticum aestivum, wheat (spring), dormancy, falling number values, heritability

Sprouting Resistance

Wheat, Triticum aestivum, with white seed coat color has traditionally been considered susceptible to sprouting. A study was undertaken to recombine white seed color with resistance to sprouting. RL 4137, a spring wheat (Triticum aestivum L.) genotype with a long, stable dormancy period and three genes for red seed color, was hybridized with 7722, a white-seeded wheat. In both the F3 and F5 generations a positive relationship existed between red seed color and sprouting resistance (SR). The six white-seeded F3 lines exhibited a range in SR from susceptible to as resistant as some red-seeded control cultivars. The mean SR of two white-seeded F4 families was intermediate to both the red-seeded and white-seeded controls at both T0 (20% grain moisture) and T10 (T0 + 10 days). Some white-seeded F4 lines had lower sprouting at T10 than the red-seeded controls Pitic 62, Neepawa, and Glenlea. The dormancy of six white-seeded F5 families derived from F3 lines was greater than the midparent value. There were significant differences among the white-seeded F5 families for mean dormancy. The results indicate that some of the dormancy of RL 4137 has been recombined with white seed coat color. The evidence suggests that RL 4137 has a genetic mechanism for SR associated with red seed color and one or more mechanisms not associated with seed color.Key words: Triticum aestivum, dormancy, white seed color

The extracted AABB component of three varieties of common wheat (Triticum aestivum L. em. Thell.) did not resemble presently grown varieties of durum wheat (T. turdigum var. durum). Relative to their corresponding hexaploid, the extracted AABB tetraploids exhibited reduced vigour, finer leaves, smaller and denser spikes, almost identical seed color, shorter stature, delayed maturity, and, with one exception, produced fewer tillers per plant. The three extracted tetraploids exhibited normal meiotic behaviour and pollen fertility.
