HONORING
PLANT BREEDER
Tim Peters
If Tim Peters has his way, we may someday enjoy a new member of
the brassica family that’s even odder than kohlrabi. Steve
Solomon, founder of Territorial Seed Company in Oregon, once referred
to Peters as “our local Burbank.” Peters has achieved
his most notable commercial successes with broccoli, a vegetable
so difficult that it could justly be called a plant breeder’s
nightmare.
Broccoli has a genetic incompatibility mechanism that prevents
self-pollination and also exhibits strong inbreeding depression,
which means that using inbreeding alone as a technique for genetic
uniformity will result in small, weak plants. Peters had to use
a whole tool chest of techniques, including bud-pollinating, crossing,
inbreeding, selecting, pooling, mass-selecting and reselecting.
When he released Umpqua in the late 1980s, it was the only decent
open-pollinated broccoli available. In the mid '90s Umpqua gave
way to #3310 Thompson, a Peters improvement which we have offered
the past four years. Peters reports further developments which he
hopes to have available soon.
Since early childhood, Peters has been fascinated by the workings
of heredity. The summer he turned 14 he figured out how to cross
pollinate tomatoes. From then on, he was a plant breeder, learning
by trial and error. By 30 he was working with Territorial Seed Company
as their trials manager and later research director, grounding him
in the varieties available and giving his breeding work a practical
focus.
In addition to broccoli, he’s introduced an intriguing line
of “Treasure” storage tomatoes. Currently he’s
working on turnip-rooted napa cabbage, kales that make broccoli
or cauliflower heads, and perennial grains including sorghum, wheat,
rye, triticale and millets.
Peters laments the slow pace and high costs of his research. He
has yet to find a way to make his work pay financially. He regards
most of his introductions to date as “just genetic steppingstones
in the path to something better. Just as we wish our own offspring
to excel, so I wish the offspring of my varieties to excel–to
do all that their parents did and more.”
