Abstract

In order to evaluate GROWTH HABIT of 151 available DURUM WHEAT varieties and lines in Maragheh Agricultural Research Station yield trials and determine correlation among some AGRONOMIC TRAITS and GROWTH HABIT, this study was conducted during three growing seasons (1998-2001).The method was the same as is usually used in the International Wheat Research Centers to determine the GROWTH HABIT of wheat genotypes. Means of AGRONOMIC TRAITS (days from planting to spike emergence and maturity, grain filling period, plant height, 1000 kernel weight and GRAIN YIELD) from yield trials were used to study their relationship with each other. Results showed that 51% of the genotypes were spring types the most frequent GROWTH HABIT among studied genotypes. Percent of winter and facultative genotypes were 33% and 16% respectively. Comparison of means for GRAIN YIELD showed that there were highly significant differences (p£0.01) among different GROWTH HABITs and the highest GRAIN YIELD (1.200 t/ha) belonged to spring types. Correlation between GROWTH HABIT and plant height was negative and significant (r = -0.16). Correlations between GRAIN YIELD and days to spike emergence, days to maturity, grain filling period and plant height were 0.51, 0.65, 0.56, and 0.47 respectively, which were highly significant. For high yielding genotypes in Maragheh and similar climatological regions selection for traits such as days to spike emergence, days to maturity, grain filling period, and plant height are recommended.
