MORPHOLOGICAL AND AGRONOMIC TRAITS CHARACTERIZATION OF SIX CULTIVARS OF LOCAL DURUM WHEAT (Triticum durum Desf.) IN OUED RIGH REGION (SOUTHEAST ALGERIA)
Keywords:genetic diversity, morphological and agronomic, plant genetic resources, wheat, yield
Wheat cultivars considered as an important model for Algerian agriculture because the shortage of water considered one of the main constraints. The current study was carried out at experimental station of National Institute of Agronomic Research of Algeria (INRAA) of Sidi Mehdi Touggourt zone. The plant material consists of six cultivars of Triticum durum Dest. The experimental plan has Randomized Complete Bloc Desing (RCBD) with four replication and nineteen biometric characters. The objective of this study was the agro-morphological characterization of six durum wheat cultivars (Tritcium durum Desf.) from the Oued Righ region. Nineteen agro-morphological parameters were used in this study. Moreover, the analysis variance (ANOVA) and the principal component analysis (PCA) highlighted a distinct variation between the studied cultivars, some of them showed good traits such as: precocity yield per plant, thousand grains weight and earing earliness, in case of Fritissi cultivar it was recorded as 40.8g, 52.38g and 102 days respectively. This inter-cultivar variability observed in current study need to be confirmed by using the biochemical and molecular markers.
