Program History




Traits in this instance means the phenotypes we are interested in and measure. These traits are intimately connected to the germplasm they are observed within so you are encouraged to visit that as well.

Presented in Alphabetical Order


Aspergillus flavus / aflatoxin resistance

Aflatoxin contamination of corn is a serious health issue as well as an economic issue. The most cost effective solution to deal with mycotoxins is likely through plant breeding.

Biomass production (leaf and stem cellulosic)

Total biomass yield is determined by many factors. Biomass can be increased by manipulation of height, tillering, stem diameter, dry matter (% water content), and harvest index.

Drought tolerance

Drought is one of the major sources of yield loss in Texas. The complexity of dealing with this trait is immense and it is often hard to seperate from heat tolerance.

Grain color

Red, blue, purple, green.

Grain composition using NIRS

Starch, oil, protein, hardness, moisture, phosphorus, nitrogen, etc. We are developing calibrations for these traits on the Thermo Anteris II NIRS. Improving phosphorus use efficiency and nitrogen use efficiency will reduce input costs to growers and reduce the enviornmental impact of agriculture.

Perennialism/ regrowth

Perennialism is the ability to grow over years. Regrowth is the ability to regrow when cut. In sorghum and maize these are highly correlated.

Stem sugar

Sorghum and maize can both accumulate high levels of non-structural carbohydrates in the stem, much like their close relative sugarcane. Mostly sugar this can be measured via HPLC or brix, a measure of soluble solids.

Quality protein maize

One of the few North American programs working on this important issue
