Yield And Yield Components

A field experiment was carried out to study the influence of sowing times on yield and yield components of barley (Hordeum vulgare L.). Seeds of four barley cultivars (BB 1, Karan 19, Karan 163 and Karan 351) were sown with four sowing times (5 November, 17 November, 29 November and 11 December). Most of the yield and yield components were significantly highest in 17 November sowing. Among the cultivars most of the characters showed their highest values in BB 1 and the lowest in Karan 19. Harvest index was found highest in Karan 351 and lowest in BB 1. Key words: Barley, Sowing time, Yield.   doi: 10.3329/jbs.v15i0.2154   J. bio-sci. 15: 139-145, 2007

SUMMARYThe effects of homozygous and heterozygous loci of 20 seedling lethal mutants on yield and yield components of barley (Hordeum vulgare L.) were studied. Nine of the 20 populations studied exhibited one locus heterosis (positive or negative advantages of Aa genotype compared with AA genotype) for yield per plant or one or more components of yield. In five instances of significance all showed positive single locus (Aa) heterosis for number of seeds per spike. Seedling lethal mutants, Ac ac and Alb,, p alb,, p showed three yield-component-heterosis. These two mutants might be suitable for hybrid barley production.

Four backcross-derived isogenic lines of Atlas barley (Hordeum vulgare L.) differing in awn length (Full-, Half-, Quarter-awned and Awnless) were grown in the field for 3 yr in northern Alberta. On the average the highest yielding line was Half-awned outyielding (P < 0.10) Awnless by 5%. Weight per seed was linearly related to awn length with a regression of 0.33 mg/cm of awn. Examination of other components of yield showed that increased awn length was associated with reduced number of spikes and florets per plant. The results suggested that the magnitude of these yield components was partially dependent on competition for nutrients during the early ontogeny of the spike between the awns at the base and the developing florets at the tip of the spike. The long daylength was suggested as a factor which might put Full-awned at a disadvantage at Beaverlodge despite high yield levels there. Application of the findings to barley breeding programs is proposed.
