Abstract

In order to identify the relationship among the NUMBER OF TILLERS per plant with GRAIN YIELD and its components in spring BREAD WHEAT at different environmental conditions, 20 spring BREAD WHEAT GENOTYPEs were grown in 7 separate RCB designs each with 4 replications in 1995 and 1996 wheat growing season in Gachsaran Dryland Agricultural Research Station, located at South West of Iran. Each experiment was carried out in two different dates (normal and late) and two moisture regimes as irrigated and dry farming in each year. During growing period data were recorded for the NUMBER OF TILLERS per plant, GRAIN YIELD and its components. Genotypic and phenotypic VARIANCEs, general heritability and genetic advance of tiller number per plant, and partial correlation of trait with GRAIN YIELD and its components were calculated. The results showed a very low genotipic VARIANCE, heritability and genetic advance for trait. Only in normal planting data-mainly in irrigated condition there were some weak and positive correlations among tiller number per plant and GRAIN YIELD and its components. In other conditions these correlations were not significant. We found that the tiller number per plant can not be considered as a direct index for selection of BREAD WHEAT lines in warm, dryland conditions of the country.
