Genetic distance estimates among single cross hybrids and correlation with specific combining ability and yield in corn double cross hybrids.
The objective of the present study was to correlate the genetic distances (GD) of single cross hybrids with yield, heterosis and specific combining ability (SCA) in the double cross hybrid synthesis. For this, 10 single cross commercial hybrids were used from different companies, and all the possible double hybrids were synthesized by a complete dialell. The hybrids were assessed in 15 location...

15 صفحه اولMonoploid Frequencies in a Commercial Double Cross Hybrid Maize, and in Its Component Single Cross Hybrids and Inbred Lines.
ARTHENOGENETIC development of the egg in maize under the stimuP lus of pollination and normal endosperm development has been noted by RANDOLPH (1939), STADLER (1949), FORTUNO (1948) and others. Data on the frequency of haploidy are meager. RANDOLPH discovered 23 parthenogenetic diploids among 17,165 individuals in the progeny of tetraploid maize, a frequency of about 1:’750. EINSET (1942) found...
متن کاملGenetic improvement of Grain Yield by Determination of Selection Index in Single Cross Hybrids of Maize (Zea mays L.)
Selection based on proper selection indices can be one of the most effective methods for indirect selection of yield and yield components, simultaneously. In order to determination of selection index for improvement of maize yield, 60 single cross maize hybrids were planted in two separate experiments (drought stress and normal conditions) based on randomized complete block design (RCBD) with t...
