C OMMON bean (Phaseolus vulgaris L.) is one of the most important vegetable crops grown in Egypt. This study was conducted to determine the phenotypic, genotypic, and environmental correlations between seed yield and some of its traits, and to perform path analysis to assess the direct and indirect effects between seed yield per plant as dependent variable and the other traits as explanatory variables.Twenty-seven accessions of common bean were evaluated at El-Dalgamon village, El-Gharbia Governorate, Egypt during the two successive summer seasons of 2016 and 2017 using a randomized complete block design with three replications.The results revealed the importance of genotypic correlations coefficients compared to the corresponding values of phenotypic ones. The genotypic correlations were positive ranging from 0.60 to 0.99 for the correlation between seed yield per plant and each of plant height, number of leaves per plant, number of days to flowering, number of racemes per plant, number of days to maturity, number of pods per plant, and number of seeds per pod. Genotypic path analysis indicated the importance of positive direct effects of plant height, number of pods per plant, number of days to maturity, and number of seeds per pod, suggesting the direct selection of these traits to improve seed yield. Whereas, number of leaves per plant, number of days to flowering, or number of racemes per plant should be selected simultaneously with plant height or number of pods per plant since they had high positive indirect effects on seed yield through these two traits.

T WENTY-SEVEN accessions of common bean were evaluated for their performance and genetic diversity based on 11 seed yield and related traits,with the aim to identify diverse accessions with greater performance to exploit the heterotic potential in hybrid combinations between them, with the possibility to obtain superior segregants in subsequent generations.The study was carried out at El-Dalgamon village, Kafr El-Zayyat, El-Gharbiya Governorate, Egypt, during the two successive summer seasons of 2016 and 2017.The accessions were arranged in a complete block design with three replications. The Tocher optimization method and unweighted pair group method with arithmetic mean (UPGMA), were used for clustering based on Mahalanobis D 2 statistic as a dissimilarity measure. The results indicated a wide genetic variability for all traits. The accessions were grouped into five clusters by Tocher's method.Cluster I was the largest, comprised 22 accessions, cluster II, which included the accessions NGB17827 and NGB17823, had the maximum inter-cluster distances with the other clusters, while each of the remaining three clusters contained only one accession. There was an agreement between UPGMA hierarchical clustering and Tocher optimization method.To obtain superior recombinants in segregating generations, we suggest investigating the crossing combinations of Giza 6 with,

to study the effect of runners' removal rates beside mothers full removal "no runners", five runners left, ten runners left and Without runners' removal and foliar spray of gibberellic acid 0 ppm, 25 ppm and 50 ppm and their interactions on vegetative growth, chemical properties, physiological traits, yield and quality of strawberry "Fortuna cv." planted under mixed planting system which fixed many runners beside mother plant with different density. Gibberellic acid (GA 3 ) was sprayed three time in 30 days intervals. The experimental design was a split plot in a randomized complete block design with three replications. The result indicated that foliar application of 25 ppm of gibberellic acid (GA 3 ) with removing all runners caused an increase in plant height, size, weight and shape index of the fruits. gibberellic acid (GA 3 ) at 25 ppm gave also the highest number of early fruits and early yield during both seasons, GA 3 also gave the highest value of TSS, vitamin C, number of leaves, number of fruits and the yield too. The study shows that it's better to use gibberellic acid (GA 3 ) with 25 ppm to spray the strawberry fruits with removing all the runners that exist beside the mother plant and that's to increase the vegetative growth and to improve the yield qualities.

Common bean (Phaseolus vulgaris L.) is one of the most important members of leguminous crops grown in Egypt for either local consumption or exportation. For highly respiring produce such as mushrooms, peas and broccoli, traditional films like LDPE. However, the micro-perforated films are special films which are expensive and not available everywhere. This experiment was carried out at Fruit Handling Department laboratories, Horticultural Research Institute. Snap bean pods were obtained from a private farm at Giza, at suitable maturity stage of marketing. Uniform pods and free from blemishes were selected for storage experiment. Pods were packed in perforated or non-perforated polyethylene and polypropylene bags (30 μm thickness, 15 × 25 cm size) and each bag had 250 g as one replicate. There were two perforation rates in addition normal perforation rate. All treatments were stored at 7°C and 90 -95 % relative humidity for 7, 14, 21days. Pods physical properties were recorded during storage.A significant decrease in weight loss percentage was observed in all perforated and nonperforated treatments in comparison with normal perforation rate. The highest weight loss was associated with those stored in normal perforation rate compared with all the other treatments. While the lowest weight loss was associated with those stored in nonperforated treatment in comparison with all other treatments. On the other side, reducing perforation rate significantly reduced decay incidence of stored common beans compared with non-perforated and normal perforated bags. Common beans stored in the less perforation rate bags was associated with the less decay incidence during storage. However, there was no significant differences among these treatments. Also, these treatments significantly reduced deterioration rate in all other studied quality of common beans during storage. Moreover, it is clear that, although common bean pods packaged in polyethylene bags had quality parameter higher than those packaged in polypropylene bags during the two seasons, there was no significant differences among these treatments in these aspects. We can conclude that, reducing bag perforation rate well led to improve common beans storability and reduce its deterioration rate during storage.
