Inbred Line Development and Hybrid
Evaluation in GEM Breeding Crosses

Objectives:
Identify GEM breeding
crosses and lines with desirable agronomic characteristics, resistance to
abiotic and biotic stresses, and high, consistent yield performance.
Materials and Methods:
Ninety-six GEM breeding
crosses were evaluated for adaptability, maturity, flowering synchrony,
standability, plant and ear height, pest resistance, stay green, grain
quality, and drydown. Inbreeding was also initiated on three new Stiff Stalk
and two non-Stiff Stalk GEM breeding crosses. Three to four hundred plants
per population were selfed. S1 ears were harvested from selected
plants based on agronomic traits, disease and European corn borer (ECB)
resistance. The major diseases were gray leaf spot and anthracnose stalk
rot. One thousand one hundred twenty-seven S1 families, derived
from eleven Stiff Stalk and two non-Stiff Stalk GEM breeding crosses, were
self-pollinated. Three hundred twenty S1 families from the
conventional mass selection and 500 S1 families from the GEM
protocol method were self-pollinated representing two breeding crosses (one
Stiff Stalk and one non-Stiff Stalk). We planted 152 S2 Stiff
Stalk and 168 S2 non-Stiff Stalk lines from the single seed
descent (SSD) breeding methodology to evaluate agronomic performance of open
pollinated ears per se. Yield tests were conducted on 215 Stiff Stalk lines
crossed to LH287 and 249 non-Stiff Stalk lines crossed to a Pioneer Stiff
Stalk tester at three irrigated locations in Delaware (two reps/location),
one location (one rep) at Ames, Iowa and one location (one rep) at Mount
Vernon/Fort Branch, Indiana. The lines were also advanced and evaluated per
se for agronomic performance.
Results:
A joint project to
evaluate GEM breeding crosses was conducted by the University of Delaware,
USDA-GEM at Ames, and Mycogen Seeds at Mount Vernon, IN. Results and
recommendations will be presented jointly by the three cooperators at the
December TSG GEM meeting. We gave higher ratings for ANTIG03:N1216,
BR105:S1612, CUBA110:N1711c, CUBA164:S2008d, DKB830:N11b20, GUAT209:N11c41,
NE19004:S2817b, NE19004:S2817c, and UR110022:S1409 based on per se rating
performance. We also suggest AR13035:S11b, CUBA164:S99f, and DKXL212:S11b
for making additional 75% breeding crosses. Based on per se evaluations for
plant height, ear placement, stalk and root strength, ear traits, maturity,
disease and ECB resistance, 212 S1 selections were made from
three Stiff Stalk and 90 S1 from two non-Stiff Stalk breeding
crosses (Table 1).
We selected S2 lines
using three different breeding methods in the FS8A(T):N1804 breeding cross.
Fifty-nine S2 lines representing 48 S1 families were selected using the
conventional mass selection method, and 59 S2 lines were selected using the
GEM protocol. Forty-seven S2 lines were selected out of 168 SSD S2 lines
evaluated per se for agronomic and disease/pest resistance. We were not able
to select enough lines from the breeding cross AR16026:S1716 to compare the
methods due to herbicide damage.
Four hundred sixty-four
S2 ears were selected from 373 of the 930 Stiff Stalk S1
families evaluated and 102 S2 ears from 92 of the 197 non-Stiff
Stalk S1 families (Table 2). A higher percentage of selections
were made from the following breeding crosses: BR52051:S1711b,
DKXL212:S0943b, and DK888:N11a17.
Yield test results are
listed in (Tables 3-14). DKXL212:S0912 derived lines have good yield
potential and high yield over moisture values with some entries comparable
to the commercial checks. The top 10-20% lines will be advanced. S3
lines from selected breeding crosses will be testcrossed on two testers and
hybrid evaluations will be conducted at more locations in summer 2006.
