Abstract

Genetic potential, combining ability, heterosis effects and heritability were studied in F1 genotypes of Gossypium hirsutum L., at Cotton Research Station in Deir Ezzor, Syria. Four parental genotypes (Aleppo 33/1 (P1), Deir Ezzor 22 (P2), Line 106 (P3) and Line G73 (P4)) and their six F1 half diallel progenies were grown in a randomized complete block design with three replications in 2011 season to study seed cotton yield (S.C.Y.kg/don.); lint percentage (L.P.%) and earliness percentage (E.P.%). Results showed significant (p≤0.01) differences among the genotypes, parents and crosses for seed cotton yield and lint percentage. Significant (p≤0.05) differences were observed for parent vs. crosses indication to average heterosis over all hybrids for the above two traits. For earliness, insignificant differences were showed among genotypes, crosses and parent vs. crosses, but significant (p≤0.05) differences were showed among parents. Results indicated that best genotypes which performed highest mean and general combining ability were: lines 106 and G73 for seed cotton yield; Deir Ezzor 22 for lint percentage and Aleppo 33-1 for earliness percentage. Thus, it could be suggested that these parental varieties could be utilized in a breeding program for improving these traits to pass favorable genes for improving hybrid and subsequently producing improved genotypes through the selection in segregating generations. Best crosses based on mean performance and/or heterosis and/or specific combining ability were Aleppo 33-1*G73 followed by Aleppo 33-1*line 106 for seed cotton yield; Aleppo 33-1*G73 for lint percentage and Line 106*G73 for earliness percentage. Suggesting that these crosses could be used in breeding program to improve such traits. On the other hand, results showed high value of H2b % and low value of H2n%for seed cotton yield,  ascertained that dominance effects had great role in the existence of the variability of this trait, which insure that the expected gain from recurrent back crossing for seed cotton yield would be high in the breeding program. However, estimates of H2b % and H2n% for both of lint percentage and earliness percentage were high. Theses convergence of narrow and broad heritability values revealed that both additive and non-additive gene actions played important roles in the inheritance of these two above traits, so breeding program should contain selection and hybridization for improving these traits.

Abstract

The present research was carried out at Pome and Grapevine Division and Horticultural Department in General Commission for Scientific Agricultural Research (GCSAR) during 2011 and 2012 seasons to study the effect of cultivar and harvest date on the productivity and qualitative characters of apple molasses. Apple fruits were collected from Golden delicious, Starking delicious and Stark rimson cultivars in two harvest dates 5/10 and 5/11. Apple molasses was manufactured and stored in normal room temperature for one year. Results showed that the second harvest date significantly produced more quantity of molasses than the first one in all studied cultivars, and Golden delicious cultuvar revealed highest productivity (7.4 Kg apple fruits/1 Kg molasses), while Starking delicious cultivar  revealed the highest productivity than the two studied cultivars in the first date (11.1 Kg apple fruits /1 Kg molasses). Chemical analysis of molasses showed that the second harvest date showed the highest content of TSS, TS, and titratable acidity in all cultivars compared with the first one, and Starking delicious molasses revealed the highest content of TSS and TS (74.75% and 64.37%, respectively) in comparison with the two other cultivars. The results indicated that after one year of storage, there were no significant differences in the color, flavor and chemical components of molasses. Consequently, apple molasses as a new product characterized by good qualitative characters.

Abstract

The present investigation was carried out at Agricultural Scientific Research Center in Latakia, during (2011-2013) to study the propagation of male kiwi trees by wooden cuttings. Two dates for collecting cuttings (January and February) from kiwi trees were selected. On every date, the cuttings were divided into three groups according to cutting location on the shoot (basal, middle and apical). The NAA and IBA regulators were applied at two concentrations (5000, 6000 ppm).  In addition, there were four treatments of the mixture of both growth regulators. The cuttings were planted within the glasshouse for 60 days under sprinkle irrigation conditions. Then, the effect of cutting collection date, cutting location on shoot and the concentration of growth regulators on; number of rooted cuttings, total number of roots, average root weight and volume, and average shoot weight and volume. The results showed that the first date (end of January) is more significant than end of February according to weight and volume of both root and shoot, also in number of rooted cuttings, where the rooting ratio was 64.9%, 54.3% respectively. According to cutting location on the shoot, the middle and basal cuttings were significantly increased in term of root weight (20.31 g, 19.81g), while the apical cutting was 15.55 g.  According root volume, the result was 20.55cm3– 20.06 cm3 and 15.57 cm3 for apical cuttings. The NAA and IBA growth regulators showed different effect; where NAA was significantly superior to IBA, and the mixture treatments in terms of the average number of roots/cuttings. While IBA and the mixture treatments were significantly superior over NAA in terms of shoot weight and volume. The treatment with the mixture (IBA3000 + NAA3000 ppm) was significantly superior to the other treatments in terms of the average weight and volume of the roots. The treatment with the mixture (IBA1500 + NAA1500 ppm) was significantly superior to the other treatments in terms of the number of rooted cuttings by rooting (75%) compering to the control (28%).

Abstract

The study aimed to analyze the value chain of fancy molasses production units by analyzing the business activities in the value chain, measuring job opportunities and identifying the main problems that affec the different actions in value chains of the production units in Egypt (the juicers). The study showed that there were idle capacities in the units of production estimated about 13 thousand tons annually during the period (2009/2010-2017/2018), which represented about 26% of the available production capacity, and there was an increase in the exports of fancy molasses or black honey during the study period at an annual rate did not prove statistically significant which estimated 0.25 tons. It was found that the most important stages of increasing chain value which need to focus on is the process of collecting reeds due to its high costs, which is estimated about 563 pounds/ton cane on average, and the estimated cost of producing per quintal (45 kg) of fancy molasses was about 210.50 pounds/quintal, which was considered the weighted selling price at which costs were equal to revenue.  The study showed that final markets for sugar cane honey were represented in three main markets i.e. wholesale markets which accounted 74.51% of the total domestic market, retail markets which accounted 15.92% and street vendors which accounted 6.9%. The average of profit of wholesalers is about 828 pounds/quintal, which is more than 3 times of the value of buying a quintal in a wholesale price (270 g/quintal), and retailers earned about 729 pounds/quintal, which is more than twice of the value of buying a quintal in retail price (360 g/quintal) and street vendors earned about 759 pounds/quintal, which represented 1.9 times the purchase price. It was found that one fancy molasses quintal produced from honey cane provides about 0.25 job opportunities, and the average of net profit of quintal is 81.40 pounds/quintal for the sugar cane production units. The average cost per quintal of the study sample is 210.5 pounds/quintal. The price of sugar cane honey is increasing with the product movements throughout the supply chain, starting from the unit sale to the surroundings for 261 pounds/ quintal, 270 pounds/quintal for wholesalers, 360 pounds/quintal for retailers and 382.5 pounds/quintal for street vendors. The product price represented a very low percentage of the consumer price, which estimated 24% for wholesalers, 32% for retailers and 34% for street vendors. The recommendations were to develop production processes, especially inputs for small units and to focus on activities that generate chain value-added, and finance through wholesale markets, also the State adoption of the problems of producers and work on them, particularly during the period of production and marketing of the product which are considered as income-generating activities for medium level families, besides providing food for low-income people.
