The present study was carried out to examine the potential in cotton germplasm for breeding water stress tolerant plant material, and understand the genetic basis of different morphological traits related to water stress tolerance. Portioned analysis of variance was employed to obtain good parents for this purposes.800px-CottonPlant The parental genotypes MNH-512, Arizona-6218, CIM-482, MS-39, and NIAB-78 were crossed in complete diallel fashion and F0 seeds of 20 hybrids and five parents were planted in the field in randomized complete block design with three replications during 2010. Simple regression analysis of F1 data revealed that additive-dominance model was quite adequate for all morphological traits. The unit slope of regression lines number of bolls (b = 1.07 ± 9.14), boll weight (b = 0.99 ± 0.11), yield per plant (b = 0.96 ± 0.31), plant height (b = 1.10 ± 0.34), leaf area index (b = 0.82 ± 0.27), and ginning percentage (b = 1.01 ± 0.12) suggested that the epistatic component was absent in the inheritance of all characters studied.

The goal of this investigation was to evaluate some qualitative and quantitative traits in fruits of five tomato (Lycopersicum esculentum) cultivars. These traits were vitamin C content, pH, total soluble solids (TSS), titrable acidity, fruit diameter, fruit volume, fruit firmness, fresh weight and dry weight. 3985483638_7c0bb7bdd8_oStudied cultivars were Matin F1, Yaghoot, Sunseed, Sadeen and Raha. The results showed that there were significant differences in evaluated parameters among cultivars. The highest contents of vitamin C (36.32 mg. 100 g-1), diameter (6.77 cm), volume (221.25 cm3), firmness (2.45 Kg. cm-2), fresh weight (194.29 g) and dry weight (11.3 g) were belonged to the cultivar Sunseed. The highest pH (4.3) and TSS (2.49 %) were belonged to the cultivars Yaghoot and Matin F1, respectively. Continue reading
