Compatibility Analysis

Following the discovery of substantial differences in the development and severity of Fusarium wilt in Linum usitatissimum L. (flax) wilt nurseries in western Canada, a study of the population structure of Fusarium oxysporum f.sp. lini (Bolley) Snyd. & Hans using vegetative compatibility analysis was initiated. Vegetative compatibility was determined using nitrate non-utilizing mutants. From a total of 105 isolates, 74 were assigned to 12 vegetative compatibility groups (VCG 0440-04411), 22 were not compatible with any other isolates and 9 did not produce mutants. The populations of F. oxysporum f.sp. lini in Fusarium wilt nurseries in western Canada were significantly different. There was a predominant VCG in each of the nurseries, which was either nonexistent or not common in other nurseries, VCG 0440 in Indian Head, 0441 in Treherne, 0442 in Morden-80, 0443 in Saskatoon, and 0444 in Morden-60. There were only three overlapping VCGs; VCG 0440 was common to Morden-60 and Indian Head and VCGs 0442 and 0444 were common to Morden-60 and Morden-80. The differences in disease development and severity observed previously may be due to the differences in the population structure of the pathogen. These findings have significant implications for the approaches to breeding for Fusarium wilt resistance in flax.Key words: Fusarium oxysporum f.sp. lini, flax, Fusarium wilt, genetic diversity, vegetative compatibility.

Alternaria Linicola

Abstract A description is provided for Alternaria linicola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Linum usitatissimum, L. grandiflorum. DISEASE: Damping off of flax seedlings. Seedlings develop a moist rot as a result of infection from the seed coat. The fungus starts by infecting the sepals and petals and is transferred to seed from the moribund flower parts. It may inhibit germination or retard debilitated seedlings. GEOGRAPHICAL DISTRIBUTION: Africa: Kenya, Tanzania. Europe: Denmark, France. UK. North America: Canada. TRANSMISSION: It is essentially a seedborne disease, but infection of the flowers must be due to airborne conidia.

New Crop

In 1971, the percentage of poorly matured flax seeds (Linum usitatissimum L.) in southern Manitoba was unusually high. This seed was discolored and tended to clump due to portions of the capsule septa adhering to the seed coat. Samples of flax seed selected from the new crop survey conducted by the Canadian Grain Commission were divided into normal and poor or weathered seeds. The poor seeds had a lower seed weight, lower percent germination, and darker oil, but an iodine number higher than the normal seeds. There were no consistent differences in oil and protein content. It appears that seeds with this type of weathering are acceptable for crushing but unacceptable for seeding.
