1 Department of Agronomic sciences, Agricultural University of Tirana, Tirana, Albania Abstract The aim of study was to establish the influence of seed size on grain yield and its components of two bread wheat cultivars. A trial was set up using randomized complete block method with three replications in Botanical Garden of Agricultural University of Tirana. Seed was divided according to their thousand weight in three fractions: 39.76, 48.51 and 58.84 g for LVS cultivar and 31.93, 39.81 and 47.02 g for Progres cultivar. Analysis of variance data showed significant effect of seed size, cultivars, and their interaction on some agronomical and productive characteristics. So, effect of seed size on spikelet per spike, grain/spike, and grain yield was significant, and non significant for seed germination, spike length and 1000 grain weight. Cultivar had significant effect on heading time, spike length, , grains per spike, spike weight, 1000 seeds weight, and yield and no significant impact on seedling emergence. Only three traits (seed spike weight, 1000 grain weight and yield) had significant differences caused by interaction seed size x cultivar. This study suggested that large seed sizes were superior as compared to small seed size in some agronomical and productive traits, including yield. Both cultivars in study had similar performance regarding to the variation in seed sizes. Keywords: Bread wheat; Emergence; Seedling; Seed size; Yield and yield components |
