The Rural Voice, 1981-04, Page 12a qualified lab for a germination test. then calls in Plant Products. On the second inspection the federal agent asks first to see the germination certificate. Next he draws random samples from the bags and subjects them to meticulous examination. "He sometimes finds things we don't want him to see", Bob jokes. This may include other type seed, i.e. barley in wheat, or weed seed categorized as - prohibited noxious, primary and secondary noxious. The first group. encompassing such pests as wild oats. field bindweed, twitch. yellow rocket and wild mustard, radish and carrot. has a zero tolerance; the remaining groups have quite low tolerance levels. The inspector carefully checks the seeds' quality. Musty darkened seed is dropped at least one grade. and there are only two categories. one and two. Bushel weight or. more accurately, weight per 1.000 kernels. must be up to minimum standard. Signs of frost damage mean diminished germination ability. and wheat harvested prematurely has a bleached -white colour. The uniformity of treatment for seed -borne diseases and insects is easily ascertained by the bright red colour of the treatment chemical. Uneven colour upsets the inspector, "and rightly so", Bob agress. "He is there to protect the farmer." if the federal agent is satisfied, he grants the seed a pedigree based on visual examination, germination certifi- cate, and the pedigree certificate issued b)• CSGA after the field inspection. He fills out some forms and prints the pedigree tags on a portable printing press he carries with him. When the inspector leaves, he takes a seed sample to send to the seed analytic lab in Toronto. Here the seed is graded under lab conditions for all the things checked by the inspector, and a second germination test is performed. The grower who has successfully passed all CSGA requirements for the first three years can begin his internship. From being a pedigreed seed grower, he graduates to probationary seed grower, "which sounds worse, but actually is better". The potential select seed grower can now obtain breeder seed (of the same crop kind as grown previously) from a university or institution such as Guelph PG. 10 THE RURAL VOICE/APRIL 1981 that maintains that kind of seed. He is allowed a limited amount, usually 30 to 35 pounds, to be planted on a much larger area than normal, in rows 14 inches apart. (Bob stayed with Fredrick wheat, and sowed one acre with his small bag of breeder seed.) The wider rows facilitate "roguing". the spotting of genetic variations. With cereal grains from the time the heads begin to form until the grain is ripe. the grower must check the seed plot every week, and then every day as maturity approaches. When the sun is low in the sky at dusk or dawn. differences in height. straw colour, hairiness of stems and length of awns can be easily spotted. All off -types are rogued - pulled out and removed from the field - as are any weeds that could present problems. The crop is inspected only once. in the field. The grower is required to clean the seed himself; CSGA stipulates that this seed must not be put into commercial channels. The seed will be replanted the following year. With most crops, breeder seed is planted initially. and genetic purity is maintained thereafter by conscientious roguing. One exception is white beans; the more generations this crop is grown in Ontario. the more bacterial blight it picks up. Because of this disease factor. new breeder bean seed is planted each year. ' If the grower is a full-fledged select seed grower. the seed he has produced is graded select; if still probationary. the seed must still meet all requirements of select seed. but is downgraded one level to foundation status. the highest level seed of commerce. After three years' internship, the persevering grower is certified as a select seed grower. abbd can apply for and obtain breeder seed of any crop he wishes to grow. He is restricted by one previso - each plot cannot exceed one-half hectare per type, and no matter how large his acreage. he can plant no more than two hectares (approximately five acres) altogether to breeder seed. The goal is not too difficult to attain. Bob Forrest claims. "The work is not intellectually de- manding, but does call for a perfectionist. a person who likes a challenge". he says. At present there are 109 select seed growers in Ontario. "Not many, but adequate", Bob remarks, and can back up his statement mathematically. "Take 25 growers of Fredrick wheat who each plant one acre of select seed that yields 70 bu. per acre x 25; the result is 1.750 bu. of select seed which. at 1'i: bu. per acre. will plant 1,167 acres of wheat. This will produce foundation at 70 bu. per acre. yielding 81.667 bu. of foundation wheat. enough to seed 54,444 acres which in turn would produce 3.811.000 bu. of registered seed. And that seed could be taken one generation further. to certified seed." Usually, according to Mr. Forrest. twice as much cereal grain is produced as is actually needed. However. last sum- mer most of the wheat grown north of 401 sprouted while standing iii head. due to the humid weather, and was not even fit for milling. Bob is also finding that barley and oats, with a normal cleanout rate of five per cent. are cleaning out this winter at 20 to 30 per cent. "Select seed production is about as close as you can get in a crop situation on the farm to having anything to do with plant genetics", Bob says. Through his job at Centralia College of Agricultural Technology he has moved even closer to one of his main interests; crop science. Three years ago he was hired to lecture senior students on forage production. cash crop production (a survey of all cash crops that could be grown in all areas served by the College) and crop fertility,. For the past year Bob has been acting head of the agronomy section of the College in the absence of Jim O'Toole. who is working on his master's degree at Western University. He will face a further challenge this summer. the: busiest time of year for a select seed grower; hs has been asked to remain at his administrative post during July and August and. among other duties, oversee 20 acres of research plots. He foresees little difficulty; he will rely even more heavily on his father "who has never yet mentioned retirement. and is in better health than I am," Bob says admiringly. Bob also employs reliable people each year to- rogue the fields. Six people can cover the Ed-El-Fo acreage in one week by systematically stringing out 30 feet apart and walking through field after field. "It's hot, dull work". !Bob admits.
