Breeding of high-yielding and stable durum wheat varieties with improved kernel characteristics is needed for dry regions around the globe. The aim this study was to investigate performance stability eight genotypes varying in their across 15 contrasting environments. tested material included three recombinant inbred lines (NUR-072, NUR-106 NUR-238) derived from a cross between Norsi, Jordanian landrace special UC1113

Abstract The use of crop varieties resistant or tolerant to insect pests other stress factors is one approach in non‐chemical crop‐protection. Knowledge the biochemical and molecular background insect–plant interactions a prerequisite for optimizing breeding resistance. However, resistance genes involved plant–aphid have so far only been identified characterized very few plant species. Our work aims elucidate mechanisms apple trees, Malus domestica L. (Rosaceae), against its primary aphid...

The current work investigates the impact of postharvest applications calcium chloride (CaCl 2 ) in combination with either 10% gum arabic or 50% cactus mucilage on quality parameters and storability tomato fruit (Izmir variety), at ambient storage conditions [21 ± 1 °C, relative humidity (RH) 45% 2%]. fruits were dipped 6% CaCl for 10 min then coated 3 min. During time-course storage, attributes, such as fresh weight loss, decay, firmness, titratable acidity (TA), total soluble solids (TSS),...

Background: The experiment was conducted at the Faculty of Agriculture and Veterinary Medicine, An-Najah National University, Palestine under growth chamber greenhouse conditions. Methods: To study effect NaCl on germination, fifty seeds in each treatment for cultivar were germinated a filter paper petri dishes moistened with different concentration levels (0.0, 50 100 mM ). plant productivity, 2 per variety grown 10 liter pots filled peat moss-sand. Pots irrigated levels. Result: tested...

This study aimed to investigate the impact of feeding by different corn silage (CS) proportions on ewes milk yield and fatty acids composition. Twenty-one lactating Assaf were divided into 3 groups (7 each). The following dietary treatments based increasing proportion CS in total mixed ratio (TMR) tested; (1) 47 % AH (0 TMR) correspond 0 CS, (2) 23.5 (23.5 50 (3) (47 100 CS. After 8 weeks feeding, type diet had no significant effect solid; however, it significantly affects fat. levels C8:0...
