Two field experiments were conducted during 2009/2010 and 2010/2011 seasons in the Experimental Farm, Faculty of Environmental Agricultural Science, El-Arish, Suez Canal University, North Sinai Governorate, Egypt (31°08'04.3" N, 33°49'37.2"E). This study focuses on response of two fodder beet cultivars (Voroshinger & Rotta) to three water stress levels (50, 75, 100 % of field capacity, FC) and four nitrogen fertilizer levels (N1= 143, N2=214, N3=286, N4=357 kg Nha ). Superiority of Rotta cultivar in leaf area index and duration was observed as compared with 1 Voroshenger cv. at most of growth periods. Net assimilation rate was increased with increasing water stress levels. Increasing nitrogen fertilizer levels from 143 to 357 t ha increased root/top ratio, leaf area index and 1 duration. Irrigat...

The present research examined the mechanisms of salt tolerance in five different quinoa genotypes at four different salinity levels (control (60), 80, 120, and 160 mM NaCl). ISSR and SCoT analysis revealed high polymorphism percentages of 90.91% and 85.26%, respectively. Furthermore, ISSR 1 and SCoT 7 attained the greatest number of polymorphic amplicons (27 and 26), respectively. Notably, LINE-6 and M-28 genotypes demonstrated the greatest number of unique positive and negative amplicons (50 and 42) generated from ISSR and SCoT, respectively. Protein pattern analysis detected 11 bands with a polymorphism percentage 27.27% among the quinoa genotypes, with three unique bands distinguishable for the M-28 genotype. Similarity correlation indicated that the highest similarity was between S-10 and Regeolone-3 (0.657), while the lowest similarity was between M-28 and L...

The cluster results of UPGMA method indicated that all the genotypes could be distinguished by ISSR markers. Six genotypes were categorized into two main clusters. Cluster I comprised Egyptian genotypes Serw-6 and Serw-4 and German genotype AD 201/Gi/81. Genotypes within cluster II comprised of French (Pactol), Chinese (Wan-you 25) and German (RG 4514).

The aim of this study is to evaluate the response of three quinoa genotype (Giza 1, Danish KVL3704 and Misr 1) to three irrigation intervals. A split plot design with three replicates using Randomized Complete Block Design (RCBD) was performed. Three irrigation intervals used were [irrigation every (3days (I1), 6 days (I2) and 9 days (I3)]. Results showed that water stress caused a significant reduction in all studied traits except for 1000 -seed weight and carbohydrates content. Increasing irrigation intervals from 3 to 9 days decreased No. of panicles per plant from 13.62 to 9.68 in 2016/2017 season and from 16.29 to 10.53 in 2017/2018 season. Increasing irrigation intervals from 3 to 9 days decreased protein content (%) by (15.11%) in 2016/ 2017 season and (15.95 %) in 2017/...
