  • Elicitation of salt stress-tolerant mutants in bread wheat (Triticum aestivum L.) by using gamma radiation

    • Authors: El-Mouhamady, Almoataz Bellah Ali;  Advisor: -;  Participants: Ibrahim, Hayam Fouad (2020)

  • This fact was proved after estimating some agro-morphological and physiological traits related to salinity tolerance based on evaluating some important genetic parameters besides salinity tolerance indices under stress experiment compared to the control treatment within two seasons. Data evaluated of expected genetic advance (GA) based on 5% selection proved that all values calculated during the two seasons under both treatments appeared low for all studied traits in this regard. However, it reflects the success of breeding for salinity tolerance in wheat using mutations but in relative terms. Molecular marker analysis profile using the six ISSR primers exhibited a total of 173 marker...

  • Elucidation of genetic diversity among some accessions of sugar beet (Beta vulgaris L.) using inter-simple sequence repeats (ISSR) markers

    • Authors: El-Mouhamady, Almoataz Bellah Ali;  Advisor: -;  Participants: Al-Kordy, Magdy Ahmad; Elewa, Tarik Abdel-Fatah (2021)

  • The process of verifying the existence of significant genetic variation between the eight sugar beet varieties with various origins was carried out through a set of genetic parameters through two growing seasons besides, the data of ISSR markers profile. Further, all the sugar beet varieties were superior in all the studied traits during their evaluation over two agricultural years, where the two sugar beet accessions Oscar Poly and Rass Poly are superior in TSS % and sucrose % traits, Mont Bianco and Sultan in apparent purity % trait, Blino and Sultan in root yield and top yield traits and Rass Poly and Blino in sugar yield trait, respectively. In addition, the values of heritability...

  • Genetic Amelioration in lentil (Lens culinaris L.) using Different Doses of Ethyl Methane Sulphonate

    • Authors: El-Mouhamady, Almoataz Bellah Ali;  Advisor: -;  Participants: Gad, Abdul Aziz M.; Karim, Ghada S. A. Abdel (2020)

  • The final results confirmed that the three lentil cultivars Giza 9 (G1), Giza 29 (G2), and Giza 51 (G3) were exhibited unparalleled superiority for all growth, germination, and other traits under study when exposed to the three doses of ethyl methane sulfonate (EMS) compared to the control. Moreover, the three doses of this mutagen exceeded on the control experiment and this superiority were most severe especially at the third dose. The higher limit of positive percentages values of induced mutagenesis in M2 lentil generation (the second mutant generation) was observed in all studied traits especially at the third dose of EMS (0.3). This fact confirmed the success of the genetic impro...

  • Improvement of drought tolerance in rice using line X tester mating design and biochemical molecular markers

    • Authors: El-Mouhamady, Almoataz Bellah Ali;  Advisor: -;  Participants: Gad, Abdul Aziz M.; Karim, Ghada S. A. Abdel (2022)

  • Twenty-three rice genotypes including eight parents and their fifteen F1 crosses or (the first hybrid generation) by line X tester analysis were evaluated for water stress tolerance during two experiments (the control and drought experiment) besides some molecular–biochemical studies for eight parents and the highest selected five crosses for water stress tolerance. The research revealed that five rice crosses out of fifteen hybrids were highly tolerant to water stress compared to the normal conditions. Data of biochemical markers indicated the presence of bands that are considered as molecular genetic markers for water-deficit tolerance in some rice genotypes, and this is the scienti...
