Aamar Shehzad | Hafeez Ahmad Sadaqat | Muhammad Asif | Muhammad Furqan Ashraf
Combining ability analysis has a key position in rapeseed breeding. To estimate the combining ability effects for yield controlling traits in rapeseed, three testers and five lines were crossed using line × tester design in randomized complete block design with three replications. Mean sum of squares of analysis of variances for genotypes were significant for all of the traits; indicating the presence of significant genetic variation. All the interactions between lines and testers exhibited significant results of mean sum of squares for combining ability. Line ‘Duncled’ was found good general combiner for decreased Plant height (PH:-2.0), Days taken to 50% flowering (DF: -15.8) and Days taken to maturity (DM:-3.4) while tester ‘Punjab Sarson” for increased Number of seed/siliqua (SS: 2.2), Number of siliquae/plant (SP: 2.2) and decreased DF (-3.0) traits. Significant general and specific combining ability effects were observed. The best hybrid combination on the basis of specific combining ability effects was “Durre-NIFA × ZN-M-6” for Seed yield/plant (SY: 2.7), DF (-6.1) and DM (-3.5). PH (-0.2), Siliqua length (SL: -0.1), SS (-0.03) and SY (0.2) showed non-additive genetic effects. The half of the characters revealed additive and remaining half showed non-additive genetic effects. The present study unveiled the importance of both type of genetic effects demanding the application of integrated breeding approaches for exploiting the variability. ‘Punjab Sarson × ZN-M-6’ exposed maximum SS (30) and SP (837). Maximum SY (75.9g) and minimum DF (64) were showed by ‘Legend × Duncled’. The present research delivers valuable information of genotypes for promoting yield by means of improving yield related characters.

Using primary energy sources in World as fossil fuels, causes air pollution and climate change. Because of these reasons, people looking for renewable energy suppliers which has less carbondioxide and less pollution. Carbon in biofuels is producing from photosynthesis. For this, burning biofuels don’t increase carbondioxide in atmosphere. Scientists predict that plants with high carbonhydrate and protein contents are 21. centuries biofuels. Potatoes are producing over 280 million in whole world and Turkey is 6th potato producer. Turkey produces 5250000 tonne of potatoes. Approximately 20% of potatoes are waste in Niğde. Our study aimed to produce bioethanol from Solanum tuberosum by using the yeast Saccharomyces cerevisiae. As a result renewable energy sources can be produced from natural wastes.

Sayed Mohammad Naim Khalid
In Afghanistan food safety is managed by several ministries including Ministry of Public Health, Ministry of Agriculture, Ministry of Commerce and municipalities. There is no food law but multiple ministerial decrees which ensure if GMP is implemented well. There is no legal requirement to get food safety certification. Hazard analysis and critical control point (HACCP) is recognized as a key part of food safety management practice in the global food industry and can be applied at any stage of the food supply chain. This article discusses accepted approaches to the application of HACCP principles for the development, implementation, and maintenance of HACCP plan. It is intended as an introduction to food safety system in Afghanistan, giving propositions to government on how to apply the principles in a stepwise approach, and showing how HACCP benefit public and private sector and also suggesting ways how to adapt this approach in the food businesses.

Başar Uymaz | Pınar Şanlıbaba
Fermentation is the oldest traditional method in order to protect against spoilage and pathogenic microorganisms. Thermal treatment, pH and water activity lowering and preservative addition other food preservation techniques that are commonly used. Although, as preservatives, many improved antibiotic and chemical agents have been gained, there are some other factors such as rapid resistance to antibiotics used in bacteria, in order to limit their use in food, to be found dimensions of threatening human health of the chemical protection and to cause allergic reactions. Recently, studies on bacteriocins that are produced by the safe bacteria, such as lactic acid bacteria, contain no toxic and adverse effects for human consumption have gained sudden intensity in accordance with the request against consumers in developing microbiologically safe and minimal processed food. There are some important effects using of bacteriocins accepted the new generation of antimicrobial agents as food preservatives such as extension of shelf life, reducing of the use of chemical preservatives and the economic loss caused degradation by microorganisms. Nisin, defined as GRAS (Generally Recognized as Safe) by FDA and named the E234 code 'Nisin-protective' or 'natural protective' located in the food additives list, first used in 1988 as a natural preservative by prohibiting of antibiotics using in food in the US. Nowadays in more than 50 countries, there have been more successful implementation of the nisin protected up the food from milk and dairy products to canned foods many food products

2015
Erol Aşcı | İsmail Durmuş
In this study, the effects of egg shape index on hatching characteristics (fertility rate, embryo mortality, hatchability of fertile eggs and hatchability), egg weight loss, chick weight, sex ratio and quality of chicks were investigated. A total of 960 eggs of ATAK- S hybrid parents obtained from Ankara Poultry Research Station were divided into three different groups (SI≤71, 72≤SI≤76, SI≤77) based on shape index and were used. A significant relationship between fertility rate and late embryonic mortality was found in the shape index groups. On the other hand, no differences were found in the rate of weight loss at 18 day, early and middle embryonic mortality, malposition rate, hatchability, sex ratio and chick quality among the shape index groups. It was concluded that shape index affected the hatching results and also that eggs of abnormal shape index should not be used for hatching.
