SHORT SUMMARY: The present research has yielded a wide array of germplasm which will serve as a potential source of rust resistance gene(s).
SUMMARY
Four inter and eight intraspecific hybrids, obtained after crossing six cultivated and two wild species of Linum, were evaluated in detail for assessment of crossability and evaluation of various agro-morphological …show more content…
sps. should be taken into account. As linseed has been domesticated for >5000 years, it can be artificially crossed with several wild relatives and produce fertile progeny (Gill and Yermanos, 1967a; Yermanos and Gill, 1967; Bari and Godward, 1970; Seetaram, 1972). While interspecific hybridization has not been documented for the most cultivated species, hybridization of flax with other n = 15 species suggests successful crossing may occur. Linum lewisii, n = 9, seems less likely to hybridized with cultivated flax (Gill, …show more content…
