Grains of eight rice mutants; SC 1, SC 6, RTY 1, RTY 3, HY 14, HYI 17, EH 4 and HYPI 22 were secured from Botany Department Faculty of Agriculture Cairo university. The procedures and the methodology for induction these mutants as well as the original mean performance of such mutants are presented else where; Sabbour, (1989) and Sabbour etal. (2002). Grains were sown (M4 generation) at the experimental farm in Itai El-Baroud Agricultural Research Station Behaira Governorate Agricultural Research Center (ARC) in the summer season (2007). The mean performance of such mutants was studied during M4 generation. The most exciting results were as follows:, the selected line SC 1 showed in M4 generation superior agronomic and yield traits. Sc 1 mutant line is not bred truly and it need more generations to reach stability. SC 6 in M4 generation showed considerable number of individuals scored low mean values toward the negative direction and lowering the over all trait mean performance. The rice lines RTY 1 and RTY 3 proved that, the average number of fertile tillers per plant of the selected lines maintained previously recorded mean values of M3 generation in M4. The traits showed significant differences among their progeny that recorded high CV% values as compared with those showed no significant differences. The rice lines HY 14 & HYI 17 showed a true breeding signs and no more breeding generations are required. Rice lines EH 4, showed a considerable reduction in number of days elapsed from date of cultivation till harvest. As, this mutant maintained 86.58 days till heading. Rice mutant line HYPI 22 did not bred truly for the original selected traits (high yield and high protein content) and it still need more generations of selection to reach considerable stability.

The present study was carried out to investegate the effect of antioxidants extracted from hibiscus calyx as natural antioxidant. Natural and synthetic ( butylated hudroxy anisol, BHA ) antioxidants exhibited strong and close antioxidative activities of 88.57% and 92.62%, respectively.
The hibisucs exteact was added to beef meat sausage at levels of 250, 500 and 1000 ppm, whereas , BHA added at levels 250 and 500 ppm to keep its quality during storage at –20ْ C for six month . Some physico – chemical characteristics were determined.
The oxidative stability of beef meat sausage with and without addition of antioxidant was determined by thiobarbitutic acid values. It was clear that the addition of hibiscus extract as a natural antioxident to beef meat sausage delayed the peroxidation during six month from 0.08 to 0.26 mg malonaldehyde / kg sample.
Color is a prime factoe in judging meat and meat products quality . The color of beef meat sausage was determind by suing Hunter Color apparatus for six month . The Hunter color values of sausage beef meat was increased after addition of natural antioxidants during storage .
It will be notice that hibiscus is a good source of antioxidant and delayed the peroxidation of beef meat sausage during storage for six month .

Production of grain legumes is limiting by the usual array of pathogenic that affect plants. The present study was conducted during 2005/06, 2006/07 and 2007/08 seasons at Sakha Agricultural Research Station (SARS). A quantitative analysis were done by using six generations mating design between five faba bean parental genotypes namely; Rena Mora, Sakha1, Giza 3, Sakha 2 and T.W to produces three crosses namely; Rena Mora x Sakha1, Giza 3 x Rena Mora and Sakha 2 x T.W. The parental genotypes could be arranged in to three groups. The first group included; Rena Mora, Sakha 1 and Sakha 2 where it is considered as the most resistant group to chocolate spot and high yielding ability. The second group included Giza 3 which is moderate resistant to chocolate spot and the third group include T.W as susceptible genotypes with low yielding potentiality. The data revealed that, the parental genotypes and their crosses had the highest value of variation according to relation to chocolate spot reaction and maturity date. Heterosis over mid and better parent for all traits were highly significant except chocolate spot reaction in the two crosses; (Rena Mora x Sakha1) and (Sakha 2 x T.W.) relative to mid parents. And also, for no. of pods/plant in the cross; (Rena Mora x Sakha1) relative to better parent. Potence ratios were exceeded unity for most traits indicating over dominance. On the other hand, the values of this parameter were less than unity in the cross; (Sakha 2 x T.W.) for maturity date, no. of branches/plant, seed yield/plant(g), 100 seed weight and chocolate spot reaction, indicating partial dominance. The inbreeding depression estimates were highly positively significant for no. of pods/plant, no. of seeds/plant and seed yield/ plant(g) in the two crosses (Rena Mora x Sakha1) and (Giza 3 x Rena Mora). The additive type (a) was significant positive or negative values in all of crosses for all traits except in the cross; (Rena Mora x Sakha 1). For dominance effect (d) it was and higher in magnitude than that of additive type of gene effects. The additive x additive gene effect was highly positive significant in most crosses except in the cross; (Rena Mora x Sakha 1) for no. of branches/plant. However, highly significant positive epistatic gene action (ad) was observed in the first cross; (Rena Mora x Sakha 1) for no. of branches/plant, no. of pods/plant, no. of seeds/plant and chocolate spot reaction. Heritability values in broad-sense were generally higher than the corresponding values in narrow-sense in all crosses for all traits. The additive genes seems to play an important role of the inheritance of maturity date, no. of branches/plant, no. of pods/plant and chocolate spot reaction in the cross; Rena Mora x Sakha1, where the differences between broad and narrow-sense heritability were closest. The indirect selection in the progeny of the crosses; Rena Mora x Sakha 1 and Giza 3 x Rena Mora and direct selection in the progeny of the cross (Sakha 2 x T.W.) would be fruitful due to the high values of narrow-sense heritability and the prediction genetic advance in these cases. The fingerprinted by SDS-PAGE of water-soluble proteins were performed in two crosses. The results reveled that bands number 2, with MWs 192KDa. was found only in cross Giza 3 x Rena Mora and also exist in the parental genotypes Giza 3 and could be considered as specific bands (positive markers) for these cross. These results support the validity of seed protein electrophoresis as a powerful tool for cultivar identification, clarifying taxonomic and evolutionary problems and studying genetic diversity of Vicia faba.

تعتبر الأسماک أحد مصادر البروتین الحیوانى الهامة ، والتى تتمیز بالقیمة الغذائیة العالیة، وسهولة هضمها ، کما أنها غنیة بالدهون والفیتامینات والأملاح المعدنیة ، کما یمکن للإنتاج السمکى أن یسهم فى حل مشکلة الفجوة الغذائیة فى الإنتاج الحیوانى .
وبالرغم من أن محافظة الإسماعیلیة من المحافظات الساحلیة وتتمتع بوفرة المسطحات المائیة بها ، کما تتمیز بتعدد مصادر الثروة السمکیة إلا أن إنتاج المزارع السمکیة إنخفض بشکل ملحوظ وبالأخص إنتاج استزراع أسماک البلطى ، مما إستلزم دراسة أسباب هذا الإنخفاض ، وکذا دراسة أهم المشکلات والمعوقات التى تواجه المزارع السمکیة بالمحافظة والتى قد تکون أحد أسباب إنخفاض إنتاج إستزراع أسماک البلطى بالمحافظة .
وبدراسة دالة إنتاج ( کوب – دوجلاس ) أوضحت نتائج التحلیل أن أهم العناصر الإنتاجیة التى تؤثر على الإنتاج الفیزیقى لمزارع أسماک البلطى هى کمیة العلف ، وعدد الأصبعیات ، والعمل البشرى ، کما تبین أنم أفضل العناصر الإنتاجیة کفاءة هما مدخلى العلف والعمل البشرى ، یلیهما مدخلى عدد الأصبعیات ، والسماد ، بینما لوحظ إنخفاض کفاءة مدخل العمل الآلى ، کما تبین من نتائج التحلیل أن الإنتاج الفعلى لعینة الدراسة بلغ حوالى 736کجم/فدان وهو أقل من الإنتاج الأمثل الذى بلغ حوالى 978کجم/فدان وبالتالى أقل من الإنتاج الإقتصادى ، ویشیر هذا إلى أن منتجى المزارع السمکیة بالعینة لم یرتقوا بعد بمستوى إنتاجهم إلى المرحلة الثانیة الإقتصادیة للإنتاج ، الأمر الذى یتطلب منهم حسن توظیف مواردهم واستخدامها بکفاءة أعلى .
وقد تناولت الدراسة أهم المشکلات والمعوقات التى تواجه مزارع إنتاج أسماک البلطى بمحافظة الإسماعیلیة وتوصلت إلى عدة مقترحات وتوصیات لمواجهة تلک المشکلات لعلها تفید متخذى القرار والممارسین للعمل فى هذا المجال إذا أخذت فى الإعتبار .

Gadallah
This investigation was carried out in the two successive seasons of 2005/2006 and 2006/2007 to study the favorable months for planting wild mint. The results indicated that plant height, number of tillers plant-1, number of branches tillers-1and fresh and dry weights of herb increased during Oct., Nov and Dec months compared with the other planting months. Also, chemical constituent i.e. chlorophyll a, b and total, carotenoids, total soluble carbohydrates concentration and oil yield were increased. On the other hand, delaying the flowering date was recorded in these months. Hence, it may be recommended to cultivate wild mint plants in Oct., Nov. and Dec. months under conditions of Fayoum governorate to obtain economical yield of herb and oil.
