Genetic Analysis for Yield Potential and Quality Traits in Maize (Zea mays L.)
Abstract: Grain yield is a complex phenomenon which results from the interaction of various contributing factors highly influenced by environmental variation. Phenotypic selection cannot directly improve the characters in heterozygous crops like maize unless dissected by genetic analysis. Gene action for various quantitative and qualitative traits was explored in a complete set of diallel invol...
متن کاملGenetic analysis of yield, yield-components and related phenological traits of maize (Zea mays L.) to breed under moisture stress conditions
Improved drought-tolerant maize hybrids would significantly reduce water consumption and increase yield in arid environments. Our knowledge about genetic parameters is very essential before starting a successful breeding program. The present research was carried out throughout three successive years between 2013-15 to reveal the pattern of inheritance in yield, yield-components and related...
متن کاملAssociation Mapping for Enhancing Maize (Zea mays L.) Genetic Improvement
Association mapping through linkage disequilibrium (LD) analysis is a powerful tool for the dissection of complex agronomic traits and for the identifi cation of alleles that can contribute to the enhancement of a target trait. With the developments of high throughput genotyping techniques and advanced statistical approaches as well as the assembling and characterization of multiple association...
متن کاملResponses of Seed Germination, Seedling Growth, and Seed Yield Traits to Seed Pretreatment in Maize (Zea mays L.)
A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. The final germination percenta...
متن کاملAllozyme Frequency Changes Associated with Selection for Increased Grain Yield in Maize (ZEA MAYS L.).
Frequency changes of alleles at eight enzyme loci were monitored in four long-term maize selection experiments. The results indicate that changes in frequencies of the alleles at these loci are associated with changes due to selection for improved grain yield. The frequencies changed more than is consistent with the hypothesis of selective neutrality. In addition, significant deviations from a ...
