A. M. M. Al-Naggar, A. M. A. Abdalla, A. M. A. Gohar & E. H. M. Hafez · Journal of Applied Life Sciences International · 2016

The doubled haploid lines (DHL) of maize in their top crosses are expected to include genotypes that accumulated favorable genes for both high-yielding and drought tolerance. The objectives of this study were: (i) to screen 254 DHL's x tester crosses for tolerance to water stress...

Heritability, Genetic Advance and Correlations in 254 Maize Doubled Haploid Lines × Tester Crosses under Drought Conditions

A. M. M. Al-Naggar, A. M. A. Abdalla, A. M. A. Gohar & E. H. M. Hafez · Archives of Current Research International · 2016

One of the major advantages of doubled haploid lines (DHL) is the maximum genetic variance between lines for testcross performance from the first generation. Two hundred fifty four testcrosses were produced as a result of crossing between 254 DHL's and an inbred line tester. The...

Breeding Values of 254 Maize (Zea mays L.) Doubled Haploid Lines under Drought Conditions at Flowering and Grain Filling

A. M. M. Al-Naggar, A. M. A. Abdalla, A. M. A. Gohar & E. H. M. Hafez · Journal of Advances in Biology & Biotechnology · 2016

Breeding value is the main parameter of initial screening through top cross analysis as it represents the general combining ability (GCA) effects of individual test line. Two hundred fifty four top crosses were produced as a result of crossing between 254 doubled haploid lines (D...
