Two investigations were carried out the experimental farm of Faculty of Agriculture, Assiut University, during the winter seasons of 2007/2008 and 2008/2009. The investigation were carried out to study the performance of five faba bean genotypes and identifying and discriminating faba bean lines. Seven RAPD markers were used to detect the genetic variability and relationships among five faba bean lines. The results of RAPD analysis showed that six out of the seven tested primers displayed polymorphism among the all tested lines, while one primers were monomorphic. 47.83% out of 69 bands amplified were polymorphic. Unique DNA fragments with different sizes were detected in particular lines but not in the others using different primers. Unique DNA markers with different sizes were related to some traits such as green pod/plants, weight of dry seeds/plant, tellers/plant and protein content percentage traits the genetic similarity among the five faba bean lines was high, ranging from 96.7% to 76%. The highest similarity and shortest genetic distance were found between Romy 80 and Romy 3. While the lowest genetic distance were found between Romy 80 and Ass. 85/37. The investigation suggested that the RAPD approach showed considerable potential for identifying and discriminating faba bean line.

A complete set of six-parent diallel crosses was evaluated in peas for five pod characters i.e. pod length, pod width, pod weight, no. of seeds per pod and 100-seed weight. From the study, there were highly significant differences among the genotypes and existence of additive and absence of non-additive effects for all the studied characters. Partial or over dominance effects controlled the studied characters and the Vr/Wr graphs confirm the analysis. Broad and narrow sense heritability were ranged from moderate to low for all the studied characters.

The present experimental work was carried out in the Vegetable Research Farm, Faculty of Agriculture, Assiut University in two summer seasons (2006 and 2007) to study the effect of two varieties; Balady Quena and Emerald, and their interaction plant spacing; 15, 30 and 45 cm between hills within ridge on productivity of okra plants. Results of the two seasons, noticed that Emerald cultivar showed earlier flowering, longer green pod, higher number and weight of green pods/plant and heavier total yield of green pods/fed. While, Balady Quena showed later flowering, longer plant height and higher branches/plant. The results exhibited that all the yield components and total yield were significantly affected by plant spacing. The wider spacing (45 cm) increased branch number/plant, and number and weight of pods/plant. However, plants grown at 15 cm produced the tallest plants and the highest yield of green pods/fed. The high total green yield may be attributed to higher plant density/fed., at plant spacing of 15 cm, compared to wider spacing. The interaction between varieties and plant spacing was significant in both seasons for plant height, number and weight of green pods/plant and total green yield/fed.

This investigation was carried out at the experimental farm of the faculty of Agriculture, Assiut University, in two growing seasons of 2007/2008 and 2008/2009, respectively to study the performance of five breeding lines of faba bean produced in general research program of Prof. Dr. Esmat A. Waly and Prof. Dr. Sayed A. Abdel-Aal (Dept. of Horticulture, Faculty of Agriculture, Assiut University).A randomized complete block design with five replicates was used, each represented by 5 plots of the lines. Each experimental plot consisted of 5 rows, 3.5 m long and 60 cm wide. Seeds of each lines were planted in hills at 30 cm apart. Data revealed that line Romy 80 gave the highest number of tillers/plant with highest green pod length (cm), green pod width (cm) and the highest value of green pod weight (g) in the first and second seasons, respectively. Line Assiut 125 had the highest number of dry pods/plant and total dry seed yield ( 1ton/fed.)
