Agronomical and Adaptation Characters of Tritipyrum Lines in Comparison with Triticale and Iranian Wheat

Abstract

In this study a Completely Randomized Design was conducted to evaluate the agronomical potential and adaptability behavior of tritipyrum lines in comparison with some triticale and local Iranian wheat varieties. The field trial was sown in October 2000 in research field of agricultural college of Bahonar University of Kerman, Iran and harvested in June 2001. All the conditions during the course of experiment were the same as for wheat in Kerman region. Nine tritipyrum lines, five triticale lines and four improved local wheat varieties were used in this study. The following traits were measured or counted on each plot, survival of plants per plot, height at maturity, tiller number, number of spikelets per spike, heading date, fertility, 1000 grain weight, biological yield, economical grain yield and harvest index. The results showed the apparent uniform growth and wheat-like morphology of tritipyrum lines in comparing with triticales and local wheat cultivars. The analysis of variance for characters studied showed a large variation between genotypes for the most traits in Kerman conditions. The mean yield in all tritipyrum lines (387 kg ha-1), in spite of having severe brittle rachis, in comparison with triticales (815 kg ha-1) and the improved local Iranian wheat cultivars (1988 kg ha-1) showed a considerable adaptability of tritipyrum lines in this first ever trail in Iran.
