Inheritance of kernel row number, a multicategorical threshold trait of maize ears.
Information about the inheritance of threshold traits is scarce, especially in plants. We examined the genetic control of kernel row number in maize (Zea mays). Knowledge of this inheritance is especially important because it is a primary component of grain yield. This trait has a discontinuous distribution. Characters like these are conceptualized as threshold traits. Crosses were made b...

متن کاملInheritance of Spotted Aleurone Color in Hybrids of Chinese Maize.
The color in the aleurone cells of maize early attracted the attention cf geneticists as affording ideal material for testing the segregation of characters in the second generation of hybrids. The first cases that were investigated led to the idea of only one unit o r factor being involved in the production of an aleurone color. With the progress of investigation, however, it became necessary t...
متن کاملKRN4 Controls Quantitative Variation in Maize Kernel Row Number
Kernel row number (KRN) is an important component of yield during the domestication and improvement of maize and controlled by quantitative trait loci (QTL). Here, we fine-mapped a major KRN QTL, KRN4, which can enhance grain productivity by increasing KRN per ear. We found that a ~3-Kb intergenic region about 60 Kb downstream from the SBP-box gene Unbranched3 (UB3) was responsible for quantita...
متن کاملExperiments on the Inheritance of Niacin in Corn (maize).
In an earlier publication the writers (12) showed that the niacin concentration of dent corn behaved as a so-called quantitative character in inheritance, being determined by many genes of small individual effects. They also showed that niacin concentration could be modified rapidly by selection and saw no reason why hybrids with niacin concentrations as high as 50 micrograms/gram could not be ...
