This study focuses on the genetic potential and genotypic stability of 17 durum wheat genotypes during three crop years under wet conditions in the north of Algeria (Algiers). The results showed highly significant (P<0.001) agro-morphological diversity between the genotypes and a genotype × environment interaction for all the traits except for fertile spikelet number. Wricke's ecovalance (w i ), Shukla's stability variance (σ i 2 ), heterogeneity variance (%HV) and the incomplete correlation (%IC) method were used to analyse the genotype × environment interaction on grain yield. The genotypes Ardente/Waha L2, Ardente and Saadi/Simeto L3 exhibited great instability with the highest values of w i , σ i 2 , %HV and %IC. Ardente/Waha L1, Simeto/Vitron L5, Simeto and Ardente/Vitron L1 had the highest grain yield and average stability (w i , %HV and %IC were weak). Significant correlations were found between %HV, R ij 2 , b i , w i , σ i 2 and %IC, implying that they were similarly efficient in detecting stable genotypes and in measuring stability.
Fruits from natural populations of wild jujube (Ziziphus lotus L. Desf.) collected from Algeria were evaluated through morphological and molecular markers. The analysis of variance revealed very highly significant differences for all the morphological characters studied (P <0.001) with coefficients of variation ranging from 7.57% to 31.84% indicating a strong variation between populations. The analysis of genetic diversity between Ziziphus lotus populations using 35 ISSR primers showed a moderate polymorphism (61.31%), a polymorphism information content of 0.35, a resolving power of 2.51 and a marker index of 0.79. Cluster analysis using SM model, classify the nine populations in two main clusters. This classification seems independent to climate change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
