Teaching
Laboratory Instructor in Genetics 110 for several years
Taught Introduction Plant Breeding, Agronomy 323 for 30+ years. Had
a total of about 350 students, undergraduates and graduate with many finding
jobs in the seed industry.
Graduate training: Advised 20 students for the MS degree
Advised
10 students for the PH.D degree
Research Interest
- Determined that upright leaf habit genotypes had a grin yield advantage
at high plant densities. In addition there is a yield advantage for
smaller tassels at high plant densities.
- In a joint project selected for high and low nitrate-reductase activity,
which is an enzyme involved in nitrogen metabolism. Selection progress
was made for higher and lower activity but was not associated with
improved performance.
- Developed germplasm from breeding in high yield environment using reciprocal
recurrent selection plus selection for multiple disease resistance.
- Using pedigree selection inbred lines were developed at three supplemental
nitrogen levels (0,60 180#per acre). When hybrids from these lines
were grown at three supplemental nitrogen levels, several hybrids reached
maximum yields at 125# of supplemental nitrogen. However, performance
was not associated with the N-level the inbreds were developed under.
- Backcrossed the low phytate-1 gene into several normal inbred lines
and found that low phytate hybrids yield less than their normal counterpart.
Other approaches need to used to lower phytate levels in maize kernels.
- Selected
for high and low ear leaf area in two maize synthetics for eight cycles.
Selection progress was made in both directions for ear leaf area in
the two synthetics and their crosses. Associated with the change in ear
leaf area was a change in leaf area above the ear. Changes in leaf area
affected flowering dates and seed size when the materials were grown at
high plant densities.
