| Summary, etc. |
During 1997, a multi-location study was conducted to assess differences in grain yield (GY) potential, under conditions of high weed infestation in the field, among 20 genotypes of bread wheat previously selected for high GY potential under weed-free conditions. Avena sativum was used as a proxy for grass weeds. The GY of wheat varied from 982 to 1951 for the 20 genotype means {i.e., averaged across the 3 locations). The two recently-released cultivars HAR 1685 and HAR 604 were significantly higher yielding than all other entries in the trial with the exception of entry 19 ( advanced line HAR 1918): At one site (Holetta), oat biomass yield was significantly and negatively correlated with wheat seedlings m-2 (WSM), wheat biomass at tillering and anthesis, and wheat GY. This suggests that higher initial wheat seedling stands and more productive canopies for specific wheat genotypes facilitated the suppression of wild oat biomass production. Similarly, the density of oat panicles m-2 at maturity was negatively affected by WSM, wheat spikes m-2 at maturity , and wheat biomass at tillering and anthesis. Oat height at maturity was significantly related to wheat height at tillering and to wheat biomass at tillering. |
