Abstract
The present study was carried out during 2009, 2010, 20 I 1 and 2012 summer
seasons at Isrnailia Agriculture Research Station, Agriculture Research Center,
Ministry of Agriculture (ARC) under supervision of Agronomy Department,
Faculty of Agriculture, Suez Canal University. The objectives of this study were
to compare two selection methods in identification of best families characterized
by high yield and yield components. Three populations in F3 generation
(population I (293 x525), population II (525x Gregory) and population III (R92
x Gregory)) used as a selection martials to produce F4, F5 and F6 generations
using pedigree and bulk selection methods.
Pedigree method:
.In the first season of 2009: F3 seeds of each population were planted with
their parent. The agronomic practices were applied as a recommended in the
region At harvest, 1000 plants were selected of each population (more than 10%
selection intensity). At lab, seeds of250 plants were selected to form the new F4
families as materials for the second cycle of selection .
•In the second season of 2010 : 250 F4 families of each population were grown
n
in a randomized complete block Design experiment with three replications. At
harvest 25 F4 families were selected for each population in each replication with
10% intensity selection .
•In the third season of 2011 seeds of 25 F5 families from each population
were grown in experiment with three replications in a randomized complete
block design. At harvest 5 families were selected for each population in each
replication with 10% election intensity.
