Relationship Between Grain Yield and Some Agronomic Characters in Durum Wheat under Cold Dryland Conditions of Iran

D. Sadeghzadeh and Kh. Alizadeh

Abstract: Abstract: The main breeding objective in drylands was drought resistance and used criterion was grain yield in the stress condition. Traits that were correlated with the grain yield may be useful for indirect selection. Negative significant correlation was obtained only between days to heading and thousand kernel weight in facultative types. In the spring types of durum wheat, days to maturity, grain filling period, plant height and days to heading were the most important traits for increasing grain yield, respectively. In the facultative types, days to maturity, plant height, grain filling period and days to heading were important but in winter types only numbers of days to maturity had positive significant correlation with grain yield. Path coefficient analysis revealed a strong direct effect of days to maturity on grain yield. However, higher DM with higher DH may interact with hot and dry weather during critical reproductive stage thus reduce grain yield of durum wheat under cold dryland condition.
