Developmental Responses

Nineteen lines of tetraploid wheat (Triticum turgidum) were examined for the presence and strength of developmental responses in the field during 1980 and 1981 and compared with lines of known vernalization and photoperiod responses in the hexaploid wheat (Triticum aestivum). Five of them had stronger vernalization responses than the winter habit hexaploid line cv. Triple Dirk C. Strong vernalization response of the tetraploids was usually associated with photoperiod insensitivity and vice versa although several lines had a combination of high photoperiod sensitivity and moderate levels of vernalization response. Compared with hexaploids the tetraploids exhibited much more variation in spikelet number per head following vernalization treatment which was less marked in some of the domesticated lines. Speculations are made on the genetic control of vernalization response in tetraploid wheat and the possible significance of greater stability in the expression of spikelet number in the evolution of wheat.

Reciprocal Crosses

Examination of seeds of parents and F1 and F2 hybrids of the crosses 'Vilmorin 23' × '61.5.3.2.' and 'Fournil' × 'Yaktana' and the reciprocal crosses showed that the C1, C2, and C3 components of the β-amylase zymogram, determined by polyacrylamide slab electrophoresis are each controlled by a pair of alleles. From the results of the second cross 'Fournil' × 'Yaktana,' a linkage study between these genes was undertaken. From previous work, we know that components C1 are located on chromosome 4 Aβ and C3 on chromosome 4 DL. We conclude that genes for C1 and C2 components are tightly linked on the same chromosome (4 Aβ).

Photoperiodic Responses

Genetic analyses were conducted of culm length, ear density, spikelet number and fertility in wheat using the two cultivars Chinese Spring and Hope and the 21 chromosome substitution lines of Hope in Chinese Spring.Elimination of differential vernalization and photoperiodic responses of the substitution lines revealed comparatively simple genetic control of these characters. Minimal estimates of the number of genes determining character expression are three for culm length, four for ear density, six for spikelet number and five for fertility. Major and minor influences of these genes have been arbitrarily determined.
