variability assessment of some maize (zea mays l.) elite inbred lines using morphological and molecular methods

Abstract: Seed samples from the breeder’s seed stocks of 11 inbred lines representing the parental inbred lines involved in the majority of the recently registered single and three-way maize crosses in Egypt were planted in South Nile Delta during 2002 season. All these inbred lines were developed and maintained by the National maize programme in the Agricultural Research Center- ARC. Since variety identification is carried out depending on the observation and recording of a range of morphological characters which can be an expensive and time consuming process. Identification and verification of maize inbred lines and other genotypes require utilizing more than one morphological attribute. Combining other biochemical and molecular fingerprinting techniques as a requirement for variety registration and national listing as well as for breeders right protection purposes and for maintaining genetic purity in the seed quality control. In this research morphological description was carried out in addition to application of the random amplified polymorphic DNA-RAPDs and simple sequence repeats or Micro-satellites- SSR as two DNA profiling techniques to investigate the variability of the 11 tested inbred lines.
