Maize hybrids are created by crossing inbreds of
opposite heterotic groups, where the discovery of
genetic distances (GD) is of great significance. With
the presence of modern breeding tools for discovering
heterotic pairs and GDs in used material an efficiency in
breeding can be increased for more precisely planned
field work.
For this study 11 crosses were made in order to
compare the prediction of data obtained by GDs
between crossed inbreds with the results of same
hybrids from field testing. Crosses were done in 2020
according to the GD suggestions which ranged from
0.386 to 0.465 to check out is it possible to predict
specific superior hybrid performance before the field
results itself. 25k SNP Ilumina Infinium Array for maize
was used to determine GD values.
As a check ZP 457-market accepted hybrid (registered
in 2018 in Republic of Serbia) was used together with
10 other hybrids. All 11 hybrids shared the same female
component (Lancaster Sure Crop heterotic g...roup),
while male components from opposite heterotic groups
(BSSS and Iowa dent) were used. GD values of used
males ranged from 0.190 to 0.412 clearly stating one
broad heterotic group. The most famous heterotic pair
B-73 x Mo-17 as well as two Institute’s top selling
hybrids (ZP 434 and ZP 606) were also included for
GD comparison with test hybrids with the GD values of
0.488, 0.466 and 0.462 respectively.
Review of B-73 x Mo-17 through ZP 434 and ZP 606
to the newly created hybrids suggests GD values are
decreasing with every new cycle of selection between
crossed material. Results from field testing compared
to GD values show somewhat positive correlation as
for ZP 3 exp which ranked 2nd highest GD value and
3rd rank in grain yield outyielding ZP 457 significantly,
but ZP 457 GD value of 0.458 (ranking third in GD)
suggests higher yielder should be though to find. Grain
yield results proved same hybrid ZP 457 to be one
of the lowest yielders being superior only to ZP 4123
despite high GD value. In top three yielders GD values
were in great correspondence for only one mentioned
combination ZP 3 exp, but for the ZP 4 exp and ZP
457 taking first and third position according to the GD
rank proved to be good only for 5th and 10th rank
within field results, while the lowest yielder ZP 4123
took 4th position according to GD values, having very
high value of 0.457.
This result proves SNP to be powerful tool in predicting
herotic pairs in maize and must be considered for
more precise planned field work. Even though GD
values being so informative on one side they do not
specifically imply to the solution for detecting the most
superior hybrid combination therefore leaving field
observations to confirm start assumptions.
