NC GEM Reports
Major Goodman
Gem families are not designed to be
replacements for FR1064 or LH287.
They originate from breeding crosses
that greatly under-perform better
commercial hybrids.
They do represent an array of good,
totally new germplasm.
Some perform remarkably well,
but
their interactions with environments
are likely to be far greater than most
highly-selected lines.
