Yield: An Almaco SPC 40 plot combine was used to har-vest the total area of each plot. Harvested grain wasweighed, moisture was determined, and yields were con-verted to bushels per acre at 14% moisture.

Ear Height: Ear height is the distance from the soil tothe highest ear-bearing node.Harvest Population: Harvest population is a measure ofthe number of plants per acre, based on actual standcounts.

Trials were conducted on Experiment Station land oron grower-cooperator fields in two geographical areas inMississippi: Area I, located in the hill region of Missis-sippi (one irrigated and four dryland locations); andArea II, located in the Delta region of Mississippi (threeirrigated locations) (see map). Commercial seed compa-nies were given the opportunity to enter hybrids ineither Area I or Area II or both. Plots consisted of two 30-inch rows, 15 feet long.

Weeds were controlled by cultivation and/or herbicides.Only herbicides currently registered for use on cornwere used in these studies, with strict adherence to alllabel instructions.

All hybrids were treated with Poncho or Cruiser forseedling insect control. Experimental design was a ran-domized complete block with four replications at eachlocation.Seed of all entries were supplied by participating com-

panies. All seed were packaged for planting at seedingrates suggested by the participating company andplanted with a cone planter. Fertilizer was appliedaccording to soil test recommendations. Plots in Area Iwere grown under both dryland and irrigated condi-tions, and plots in Area II were grown under irrigatedconditions. All irrigated trials were either furrow or cen-ter-pivot irrigated, as necessary.

PROCEDURES

VARIABLES MEASURED IN THE CORN HYBRID TESTS

Mississippi Agr icultural and Forestry Exper iment Stat ion 1

The yield potential of a given hybrid cannot be measuredwith complete accuracy. Consequently, replicate plots of allhybrids are evaluated for yield, and the yield of a givenhybrid is estimated as the mean of all replicate plots of thathybrid. Yields vary somewhat from one replicate plot toanother, which introduces a certain degree of error to thevalue. As a result, although the mean yields of some hybridsare numerically different, the two hybrids may not be signif-icantly different from each other within the range of naturalvariation. That is, the ability to measure yield is not preciseenough to determine what the small differences are, otherthan what might be observed purely by chance.The least significant difference (LSD) is an estimate of

the smallest difference between two hybrids that can bedeclared to be the result of something other than ran-dom variation in a particular trial. Consider thefollowing example for a given trial:

Hybrid Yield A . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90 bu/A B . . . . . . . . . . . . . . . . . . . . . . . . . . . . 85 bu/A C . . . . . . . . . . . . . . . . . . . . . . . . . . . . 81 bu/A

LSD . . . . . . . . . . . . . . . . . . . . . . . . . . 7 bu/A

The difference between hybrid A and hybrid B is 5bu/A (i.e., 90 - 85 = 5). This difference is smaller than theLSD (7 bu/A). Consequently, we would conclude thathybrid A and hybrid B have the same yield potential,since we are unable to say that the observed differencedid not occur purely due to chance. However, the differ-ence between hybrid A and hybrid C is 9 bu/A (i.e., 90 -81 = 9), which is larger than the LSD (7 bu/A). Wewould therefore conclude that the yield potential ofhybrid A is superior to that of hybrid C.The coefficient of variation (CV) is a measure of the

relative precision of a given trial and is used to comparethe relative precision of different trials. The CV is gener-

ally considered an estimate of the amount of unex-plained variation in a given trial. This unexplainedvariation can be the result of variation between plotswith respect to soil type, fertility, insects, diseases, mois-ture stress, etc. Overall, as the CV increases, theprecision of a given trial decreases. The coefficient of determination (R2) is another measure

of the level of precision in a trial and is also used to com-pare the relative precision of different trials. The R2 is a

measure of the amount of variation that is explained, oraccounted for, in a given trial. For example, an R2 value of90 percent indicates that 90 percent of the observed varia-tion in the trial has been accounted for in the trial, with theremaining 10 percent being unaccounted for. The higherthe R2 value, the more precise the trial. The R2 is generallyconsidered a better measure of precision than the CV forcomparison of different trials.
