The combining ability and the nature of gene action were determined for economic traits under combined data of tow sowing dates. Genotypic mean squares of were highly significant for all studied traits. Moreover, mean squares due to genotype×environment interaction (G×E) were highly significant for these traits except pod weight, suggesting a differential response of the genotypes from environment to another. The results indicated that the majority of crosses were significantly earlier, taller and higher yielding than their mid parents. Furthermore, there are some crosses showed desirable heterotic values over their better parent for the majority of traits. The results indicated that the magnitudes of the non-additive genetic variance (σ 2 D) were higher than those of additive ones (σ 2 A) for the majority of studied traits indicating the importance role of non-additive gene action in the inheritance of these traits. However, the magnitudes of σ 2 D×E interaction were more than σ 2 A×E for all studied traits. The largest value of broad sense heritability (98.80%) was recorded for pod weight, while the lowest value (36.22%) was observed for pod length. The estimates of narrow sense heritability ranged from 18.21% to 45.69% for numbers of days to flowering and plant height, respectively. These findings confirmed the predominance of non-additive genetic variance over additive one in the inheritance of these traits. Therefore, the promising crosses which showed desirable specific combining ability (SCA) effects and gave also high estimates of useful heterosis could be utilized for okra hybrids.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133297903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A control sample was prepared without any additives. The other twelve mixes were fortified with % 1 (wt/wt) Inulin. Physiochemical properties of yoghurts were evaluated during cold storage for 14 d. The results showed that increasing the added ratios of different dried dairy ingredients and inulin led to the increase in total solids, protein, soluble nitrogen, acidity, and ash content, whereas the fat percentage did not affect. Enrichment of non-fat yoghurt with different dried dairy ingredients and inulin caused a decrease in the pH values. There was a negative correlation between syneresis and the added percentage of dried dairy ingredients and inulin. During storage, the total solids content, protein, soluble nitrogen, fat, ash, acidity and syneresis were increased in contrast with pH level. This study suggests that the using mixes of the different dried dairy ingredients in appropriate ratios along with inulin seems as a useful and interesting approach for manufacture of non-fat set yogurt.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114141450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present results indicated that there are no clear differences among (TSS) and water content (%) means of different honey types. There were relative difference among honey types in PH and HMF content. The PH values ranged between 3.38 and 4.57. The HMF values ranged between 4.48 and 7.68 mg/kg. The highest HMF content was recorded in poly floral honey and the lowest one was recorded in clover honey. The present data confirmed that characteristics of honey samples were related to their floral sources and season of extraction.

Three nitrogen/potassium rates (90N: 48K, 120N:90K and 150N:120K units feddan. The obtained results clearly showed that there were significant differences among the four cultivars and the three levels of fertilization among the most of studied characters under this study. The cultivar Chara is the best one on the total yield (9.88 and 10.03 ton/ fed), yield component and most of quality traits. In the case of sowing in the sandy soils under Sohag conditions it was been that the third level (N150:K120) gave the best results. Sponta cultivar was the best on some of the quality traits such as dry matter and starch. Finely the cultivar Chara with the third level of fertilization is the best in the total yield and its components and most of quality traits. INTRODUCTION Potatoes (Solanum tuberosum L.) is considered one of the most important strategic crops for the populations all over the world and comes at the fourth stage after wheat, rice, and maize. It plays a vital role in the Egyptian diet it has production nearly 4265178 tons from about 381379 fed with average yield 11.184 ton per fed (Agriculture Directorates in Governorate, 2014). Potato is considered as the most important tuber crop. Moreover it is an important vegetable and a good source of antioxidants. Potato is a major source of inexpensive energy; it contains high levels of carbohydrates and amount of vitamins B, C and minerals (Muthoni and Nyamongo 2009).The tubers are a good source of starch, proteins, vitamins, sugars, minerals and other useful substances when eaten as an essential dish and with major quantities for long time (Blagoeva et al., 2004).

Legume seeds are a good source of phosphorus compounds. Phytic acid contents in raw legume seeds such as faba bean, lentil, pea, chickpea and kidney bean were 1.10, 0.95, 0.86, 0.73 and 1.20%, respectively. The highest phytase activity was found in the germinated faba bean for 144 hrs with partial purification by acetone 80%. Soaking process of legumes with ordinary water without addition of phytase extract led to minimal reduction of phytate content in all tested legumes. The reduction rate of phytate was 6 and 12% of its initial content in raw seeds after 8 and 12 hours, respectively. The hydrolysis of phytate was enhanced with increasing ratio of added phytase extract to water (45 : 55) during soaking for 12 hrs. A significant reduction in phytate content during the germination process as a result of the phytase extract addition was found. The loss rates of phytate were 47.9, 59.2, 70.4, 75.8 and 90.3% of its content in raw seeds after 24, 48, 72, 96 and 120 hrs respectively. The high loss of phytate content during soaking and germination was due to the addition of high activity enzyme extract as well as the endogenous enzyme effects. As a result of phytate hydrolysis during germination, the inorganic phosphorus(Pi) in all germinated legumes was librated in a large amounts with addition exogenous phytase compared to the phosphorus released by the native phytase.","PeriodicalId":139703,"journal":{"name":"Journal of Sohag Agriscience (JSAS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129047742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
