Book Description
Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100, 160, and 240 Kg/ha) and at two seeding dates (October 13 and November 12). A similar experiment was conducted at the Sherman Experiment Station, Moro in Eastern Oregon, using only two winter wheat cultivars, Stephens and Jackmar. Data were obtained on grain yield, tillers and spikes per square meter, heading and anthesis date, plant height, kernels per spike, 1000 kernel weight, test weight and harvest index. At Hyslop Experiment Station, Stephens, Bezostaya and Roussalka produced maximum grain yield at 10 cm row spacing and 160 Kg/ha seeding rate, and Maris-Hobbit at 24 cm row spacing and 160 Kg/ha seeding rate. At Sherman Experiment Station, 30 cm row spacing and 90 Kg/ha seeding rate constitutes the best combination for Stephens, and 30 cm row spacing and 120 Kg/ha seeding rate for the club wheat Jackmar. The interaction between row spacings x cultivars and seeding rates x cultivars indicated that all the cultivars produced high numbers of tillers and spikes per m2 at narrow (10 cm) row spacing and high (240 Kg/ha) seeding rate. There were no significant differences between row spacings for heading and anthesis date. Lower seeding rate resulted in later heading date. The cultivar Roussalka was the earliest and Maris-Hobbit the latest in average heading date, Plant height decreased with increased row spacing and increased with increased seeding rate. The plants of the four cultivars were shorter at the second date than at the first. More kernels per spike were produced at the second than at the first date. An increase in seeding rates was accompanied by a decrease in the number of kernels per spike. There were no significant differences between the three row spacings, the three seeding rates and the four cultivars for test weight. The different row spacings and seeding rates did not affect the TOGO kernel weight. Considering the cultivars, Stephens produced a higher 1000 kernel weight at the two seeding dates than Maris- Hobbit, Bezostaya and Roussalka.
