dc.descriptionThe present study was carried out to determine the contribution of main stems and tillers to the total yield of two wheat cultivars (Triticum aestivum L.), Cocoraque and BH-1146, under two water treatments: a) normal field conditions, and; b) irrigation, in Londrina, PR, Brazil. The experiment was an eight replication randomized complete block design with treatments arranged in split-plots. Data on total grain yield, main stem grain yield, tillers grain yield, the ratio between tiller and total grain yield, yield components and other 17 traits were collected. The cultivar BH-1146 had a higher total grain yield in relation to Cocoraque under normal field conditions; i, e., under water stress. Main stem grain yield responded positively and significantly to irrigation which was the main cause of increased yield in both cultivars. The tiller grain yield contributed little to the total yield.
