FIELD EVALUATION ON NONSALINE SOILS OF A SOMACLONAL VARIANT OF McGREGOR FLAX SELECTED FOR SALT TOLERANCE IN VITRO

Abstract
Field experiments, comparing the performance of a tissue-culture-derived salt-tolerant selection (STS) of McGregor flax (Linum usitatissimum) with the cultivars McGregor, Linott, Noralta, NorLin and NorMan, were sown at three nonsaline locations in Saskatchewan in 1984 and 1985. The salient feature of this experiment was the dissimilarity of STS to its parent, McGregor. STS yielded less, was earlier to bolt, flower and mature, and had larger seeds with a lower oil content than McGregor. The yield of STS was similar to other early-maturing cultivars under test.Key words: Linum usitatissimum, somaclonal variation, seed yield
