Abstract

This research aimed to study the morphological characterization and to determine the  variability among twenty Rosa damascene genotypes, which grown in different areas of  Latakia and  compare them with two genotypes from Marah location at the countryside of Damascus to  take advantage of high quality characteristics  in order to be improved in the future, and  to enhance its cultivation. The results of morphological characterization  of forty traits showed a clear difference between some studied genotypes. The highest differences were related to flowers and vegetative characters compared with fruits and seeds characters.  A dendrogram based on the morphological data showed clear separation between studied genotypes, and reached (85%) for flowers characters and reached (60%) for vegetative characters, while it attained (47%)  for  fruits and seeds characters. The study showed that there were a distinct differences for some genotypes which can be used in breeding and genetic improvement programs in the future.

Abstract

Thirteen local and entries tetraploid genotypes of durum wheat (Triticum durum Desf.) were planted at Izra’a Station (Dar’a Centre), General Commission for Scientific Agricultural Research GCSAR, during three seasons (2013/2014, 2014/2015 and 2015/2016) under rainfed conditions, in addition to the local variety Sham3 as a check in a Randomized Complete Block Design RCBD with three replications. The studied traits were (days to maturity, plant height, spike number per plant, spike length, weight of grain per spike, weight of thousand grains and individual plant grain yield) in order to evaluate the variance between genotypes and seasons and the interaction between them, and to define the superior genotypes to provide them to the breeding programs. Results showed that the genotype wheat1527 was significantly superior in spike length, grain weight per spike, thousand grains weight, and individual plant grain in a rate of 36.92, 32.10, 21.43 and 36.47% respectively, compared to the check variety Sham3. Results also showed that the genotype wheat 1471 was significantly superior in spike number in a rate of 23.07% comparing to the check Sham3 as the number of spikes in plant was (10.67, 8.67) for each of them respectively. Each of plant grain yield, spike length, spike number per plant and days to maturity were all significantly superior during the season 2016 comparing to both seasons 2014 and 2015.

Abstract

The study was conducted between 2015 and 2017 on 26 species of Ceratonia siliqua L. at four locations viz. AL Dakaka, Wadi Qandil, Um Al-Toyoor and Al-Baseet, in the north-western region of Latakia governorate, Syria in order to study some chemical properties in the pods and seeds of these species. For total sugars (%), the highest percentage was found in T8 pods (57.7%) followed by the D3 (56.9%). The percentage of protein in the pods ranged between (5- 8.2%) and seeds (25-33%) where T8 recorded the highest values. The highest fat value was found in T8 (1.83%) and D3 (3.75%). The percentage of dry matter in the pods ranged from 12.15% in K3 and 8.16% in T1. These genotypes differed genetically more than because of environmental conditions because the locations of the study were geographically close. The genotypes were distributed within the relationship tree in three groups, the first included 3 genotypes and the third contains 9 genotypes from all the study locations. In contrast, the second group included 4 genotypes from the locations of Um Al-Toyoor, Wadi Qandil and Al-Dakaka.

Abstract

The present research carried out at AL Salamieh city, Hama Governorate, during the season 2015, aiming to evaluate the morphological traits of three genotypes of sweet corn i.e Faihaa1, Randevo and Snekofa Karaliva under the effect of different sowing dates; 1st and 15th April, in order to determine the best variety and the most suitable sowing date in spring season. The results showed that the morphological traits of Faihaa1 genotype was higher than those of Randevo and Snekofa Karaliva in the first sowing date (1st April), and the increase of ear length recorded (1.78-1.48 cm), and height of plant recorded in Faihaa1 and Randevo and Snekofa Karaliva were (130.95, 71.11 and 68.33 cm) respectively. Also, the results showed that there was a significant increase in kernel diameter, leaf area, and stem diameter in Faihaa1, comparing to Randevo and Snekofa Karaliva, while the highest ear length and kernel diameter were at the beginning of April for all genotypes.

Key words: Sweet corn, Genotypes, Sowing dates.

Abstract

The study was conducted at Al-Ghab Research Centre, General Commission for Scientific Agricultural Research (GCSAR), Hama, Syria, during two growing seasons 2012/2013 and 2013/2014. Eight primitive wheat genotypes; C49, C57,and C64 belongs to Ttiticum carthlicum; P149,and P193 belongs to Ttiticum polonicum; D94, D124,  and D67 belongs to Ttiticum dicoccom, and two local cultivated varieties sham3, and sham5 (as control) were planted in randomized complete block design in three replications. Yield components (number of fertile tillers, number and weight of grains per spike and weight of thousand grain) were studied and compared to the  control and also the correlation coefficient  between the studied traits was determined. Results showed that the genotype D94 was significantly superior in number of fertile tillers comparing to both controls, and the genotype P194 was significantly superior in weight of grains per spike with an increase rate (76.65, 97.99)% as compared with both controls, sham3, and sham5, respectively, and also was significantly superior in weight of thousand grain with  an increase rate (72.73, 107.28)% as compared with both controls; sham3, and sham5 respectively. The results also showed a positive correlation between number of grains per spike and with each of weight of grains per spike and weight of thousand grain.

Abstract

The study was conducted at Izraa Research Station and Cereal Technology Lab of The General Commission for Scientific Agricultural Research (GCSAR) in Syria, during two growing seasons 2009/2010 and 2010/2011. Fifteen local and entries genotypes and three local cultivated varieties were planted in Randomized Complete Block Design RCBD in three replications, Correlations and Regressions between number and weight of grains per spike with quality components contents in grains were studied after harvest. Results showed that number of grains per spike had a negative and significant correlation with each of protein content and wet gluten content and sedimentation rate, while it was positive with starch content in grains. Weight of grains per spike had a negative and significant correlation with each of protein content and wet gluten content. Results showed that all regression relations were negative and significant, thereby breeding programs for increasing number of grains per spike will cause a reduction in each of protein content and wet gluten content and sedimentation rate about (36, 17, 17%) respectively, while breeding program for increasing grain weight per spike will negatively affect protein and wet gluten content in grains about (28, 14%), respectively.

Key Words: Productivity components, Quality components, Correlation, Regression, Genotypes, Primitive Wheat.
