Identification of SSR Molecular Markers for Jassid Resistance in Cotton
Background: This study has focussed on identifying the Simple Sequence Repeat (SSR) markers associated with the sucking pests (more precisely on jassid) tolerance/resistance loci. The study was initiated with 4348 mapped SSR markers to differentiate between resistant (R-1) and susceptible (BS-1) genotypes. Out of 4348 markers (retrieved from cotton microsatellite database and cottongen.org) used,17 markers were showing polymorphism between the parental lines. Methods: The F1 population was generated by crossing Resistant line (R-1) and the elite Susceptible line (Bs-1). F1 progeny were selfed to obtain F2 population. Following the screening, to identify the SSR markers associated with trait, Single Marker Analysis was performed. Result: The results indicated that two of the seventeen polymorphic markers - BL1646 and DOW047 had significant LoD of 4.5 and 7.2 respectively and PVE% of 6.6 and 10.3 respectively. Hence, these were identified as the two markers associated with jassid resistance trait having the potential for their use in marker assisted selection (MAS).
