The 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 ...

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 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 کاملMaize Stalk As Reinforcement In Natural Rubber Composites
Maize stalk fibres can be used as fillers in natural rubber composites replacing expensive and non-biodegradable inorganic fillers. Maize stalk fibres were chemically modified with acetic anhydride (acetylation) to enhance their compatibility with the hydrophobic rubber polymer matrix. The fibre was characterised using FTIR showing a spectrum with a well defined peak at 1742 cm -1 (attributed t...
