Seed of four triticale (Triticale hexaploide Lart.) cultivars, two wheat (Triticum aestivum L.) cultivars, and one rye (Secale cereale L.) cultivar were harvested at 4-day intervals from 6 to 42 days post-anthesis. Alpha-amylase activity was determined in the embryo, pericarp, aleurone, and endosperm of the seed. In all cases, the α-amylase activity in the embryo was low. The pericarp activity reached a maximum in all samples at approximately 10–15 days post-anthesis. Aleurone and endosperm activity remained low throughout the development period in all but one triticale cultivar. In triticale cultivar 6A 190, the aleurone and endosperm α-amylase activity remained low until approximately 20–25 days post-anthesis, at which point the activity increased to levels normally associated with sprouted grain. Light microscopic examination of the 6A 190 at 10 days post-anthesis showed that the starch in the inner portion of the pericarp was digested. At 22 days, all pericarp starch had disappeared. Specific lesions in the endosperm and aleurone cells were observed beyond 22 days. Areas of the endosperm where starch damage due to α-amylase could be seen were often associated with regions possessing necrotic tissue located between the aleurone and endosperm. In some areas, aleurone cells were completely absent.

The Rht-B1b, Rht-D1b and Rht-B1c alleles for reduced height in wheat (the Norin 10 and Tom Thumb dwarfing genes previously known as Rht1, Rht2 and Rht3) were exploited in combinations to generate a near-continuous range of plant heights, from 53 cm to 123 cm, amongst near-isogenic homozygotes and F1 hybrids. Pleiotropic yield effects of Rht genes were measured in both homozygous (intravarietal) and heterozygous (intervarietal) genetic backgrounds. Heterosis due to overdominance of Rht genes was detected among intravarietal hybrids. The effects of heterozygosity at other genetic loci (mean dominance) were determined, independently of Rht effects, from comparisons between intravarietal and intervarietal F1 hybrids.Genotypes of intermediate plant heights gave maximum yields, in agreement with other trials of the homozygous lines, so that heterosis (hybrid exceeding best parent) for Rht yield effects was observed in crosses between tall and dwarf isogenic pairs. This heterosis combined additively with increased mean weight per grain in intervarietal crosses, generating the highest overall grain yields in hybrids with semi-dwarf stature in heterozygous genetic backgrounds. The Rht-B1c allele showed single-gene overdominance for grain yield, also the production of alpha-amylase in ripening grains of Maris Huntsman was effectively inhibited in the Rht-B1a/c intravarietal hybrid. The Rht-B1c allele thus offers advantages for both grain yield and grain quality in the heterozygous condition and should be considered as an alternative to the conventional semi-dwarfing genes Rht-B1b and Rht-D1b for F1 varieties in environments conductive to preharvest sprouting.
