Five cycles of single-plant and progeny-row selection in lines derived from Brassica rapa L. "Tobin" were used to identify plants with incomplete resistance to flea beetles, Phyllotreta cruciferae (Goeze). This line, called C8711, had higher survival, grew larger, and yielded more seed than Tobin when the two lines were compared in field plots at Glenlea, Manitoba, unprotected by insecticide. C8711 without insecticide yielded more seed than Tobin treated with a lindane seed dressing, but less than Tobin treated with carbofuran granules. With carbofuran, which prevents most flea beetle damage, the yield of C8711 was 35% higher than for Tobin. At Saskatoon, Saskatchewan, the differences between C8711 and Tobin were not statistically significant, although the trends were similar to those at Glenlea. C8711 was late maturing, produced small seed, and was not of canola quality. The resistance in C8711 is attributed to a low level of antixenosis, rapid growth at the cotyledon stage, and tolerance to damage during the first 3–4 weeks of growth.

Cinq cycles de sélection à partir de plants individuels et de rangées de plants-fils au sein de lignées dérivées de Brassica rapa L. "Tobin" ont permis d’identifier une lignée à résistance incomplète à l’Altise des crucifères, Phyllotreta cruciferae (Goeze). Cette lignée, appelée C8711, avait une meilleure survie, donnait des plants plus grands et produisait plus de graines que la lignée Tobin, au sein de cultures faites dans des conditions comparables, sans insecticides, à Glenlea, Manitoba. La lignée C8711 sans insecticide a produit plus de graines qu’une culture de la lignée Tobin obtenue à partir de graines traitées au lindane, mais moins qu’une culture de Tobin traitée aux granules de carbofurane. En présence de carbofurane, qui protège les plants contre la majorité des dommages dus à l’altise, la production nette de C8711 était de 35% plus élevée que celle de la lignée Tobin. A Saskatoon, en Saskatchewan, les différences entre C8711 et Tobin n’étaient pas statistiquement significatives, bien que les résultats aient indiqué les mêmes tendances générales qu’à Glenlea. Chez la lignée C8711, la maturation était tardive, les graines produites étaient petites et les plants n’étaient pas de qualité canola. La résistance de C8711 est attribuable à sa faible concentration d’anti-xénose, à sa croissance rapide au stade cotylédon et à sa tolérance aux ravages au cours des 3 ou 4 premières semaines de sa croissance.
