Genetic Relationship of Stalk Strength and Ear Height in Maize
creased by 22.5% over five cycles of selection for high RPR in MoSCSSS. The correlation between RPR and The rind penetrometer is an effective tool for measuring stalk EH is of interest in terms of direct vs. indirect selection strength in an effort to improve maize (Zea mays L.) germplasm for stalk lodging resistance. However, previous studies have indicated a for stalk strength. That is, to wh...
متن کاملThe Genetic Architecture of Maize Stalk Strength
Stalk strength is an important trait in maize (Zea mays L.). Strong stalks reduce lodging and maximize harvestable yield. Studies show rind penetrometer resistance (RPR), or the force required to pierce a stalk rind with a spike, is a valid approximation of strength. We measured RPR across 4,692 recombinant inbreds (RILs) comprising the maize nested association mapping (NAM) panel derived from ...
متن کاملInsect Resistant Maize: Implications for Ear and Stalk Diseases
The evolution of genetically modified crops took a major step in the mid-1990s with the approval and commercial release of insect-resistant maize hybrids with transgenes derived from the bacterium Bacillus thuringiensis (Bt maize). The release of Bt maize was met with great enthusiasm by many researchers and crop managers because of its ability to very effectively control European corn borers a...
متن کاملThe Genetic Architecture Of Maize Height
Height is one of the most heritable and easily measured traits in maize (Zea mays L.). Given a pedigree or estimates of the genomic identity-by-state among related plants, height is also accurately predictable. But, mapping alleles explaining natural variation in maize height remains a formidable challenge. To address this challenge, we measured the plant height, ear height, flowering time, and...

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
