Abstract

Belonging to the
Oomycete genus, Phytophthora capsici is responsible of many devastating disease
and the most destructive agent of pepper in the World.  The most cost-effective method for preventing
Phytophthora blight is to use resistant cultivars. In this
study, the polygenic resistance of improved pepper lines to Phytophthora Blight
were screened by molecular markers placed on three chromosomes in pepper. Sena
variety registered as suitable for spice pepper production was used as susceptible
female donor and CM 334 and Perennial genotypes were used as male resistance
sources. Thirty two genotypes were screened by ASC 035 marker placed on
chromosomes P10, ASC 037 on P5 and ASC 031 on P2. Twelve of these improved red
pepper lines from different resistance sources were exhibited polygenic
resistance according to electrophoretic signals to all of three markers placed
on P2, P5 and P10. In order to determine codominance of the resistance genes
PCR products of ASC 031 and ASC 037 were restricted by HaeIII and EcoRI respectively.
Ten improved lines exhibited codominance related with resistance to
Phytophthora Blight concerning ASC 031 and only one line was showed codominance
for ASC 037. Three different lines had one resistance gene on P5 and on P10
independently. Only T12 line holds two resistance genes both P2 and P10. DD and
63 lines were most promising genotypes related with their resistance to
pathogen. Molecular assisted selection was found useful for improving
Phytophthora resistant red pepper lines.
