Abstract

The present investigation carried out in experimental farm of faculty of agriculture saba basha, Alexandria university and Sabahya horticulture research station through 3 winter successive season of 2016/2017, 2017/2018 and 2019/2020. On broad bean variety explained as follows:
1- (P1) Reina mora (Spanish variety).
2- (P2) Luz de onto (Spanish variety).
3- (P3) Giza planka (Local variety).
4- (P4) isolated line from Sabaty.
5- Line Produced from cross (P1×P2) (P1: Reina mora × P2: Luz de onto).
6- Line produced from cross (P2×P1) (P2: Luz de onto × P1: Reina mora).
7- Line produced from cross (P1×P3) (P1: Reina mora × P3: Giza planka).
8- Line produced from cross (P3×P1) (P3: Giza planka × P1: Reina mora).
9- Line produced from cross (P3×P4) (P3: Giza planka × P4: Sabaty).
10- Cleopatra as a test variety, developed by the Agricultural Research Center.
Selection with self-pollination was conducted for 5 isolation of broad bean, by two methods of selection were used, namely mass selection and individual selection of some important characteristics associated with early yield and high productivity of the crop, as these characteristics were as follows:
1-Number of nodes to the first pod appears. 2- Stem thickness.
3- Number of branches. 4- Plant high
5-Number of days until the first pod appears. 6- Pod length
7-Average pod width 8-Average pod weight
9-Average number of pods / plant 10- Total fresh yield / plant.
11- Average number of seeds / pod 12- Total dry yield / plant.
In separate evaluation season (11 November of 2018/2019) 9 population were planted, tow population from each parents, 2 strains from original population, 2 strains from first mass selection generation, 6 strains from first individual selection generation, 2 strains from second mass selection generation, 6 strains from second individual generation and check cultivar Cleopatra. In randomized complete block design with three replicates Experimental units with a seed / hole on lines 4 meters long and 80 cm wide, and the distance between the hills is 40 cm. 10 plants were selected for each genotypes to assess the previous characteristics. Rough treatment, irrigation, fertilization, weed control and pests were also carried out according to the recommendations of the Ministry of Agriculture and Commercial Production. To measure the amount of progress in yield and its components and early yield traits of broad bean for two cycles in both selection methods, in addition to a comparison between the progress in using the mass and individual selection and documenting the difference between progress using both methods. In addition genetic parameters like phenotypic and genotypic variance, phenotypic and genotypic coefficient of variance, heritability estimates, genetic advance, inbreeding depression, path analysis, correlation coefficient analysis and compared the development which achieving by two different selection methods.
