Abstract
INTERSPECIFIC hybridization in the genus Lathyrus has been attempted by several workers with little success. Barker1 obtained viable, partially fertile hybrids from the cross L. hirsutus × L. odoratus. Taylor2 claimed to have produced seeds by crossing L. odoratus with L. pratensis reciprocally. It has not been possible to repeat this cross. Senn3 reported failure in 458 attempts at intercrossing seventeen species of Lathyrus and Pisum sativum. Marsden-Jones4 successfully crossed L. rotundifolius with L. tuberosus. In this Department viable seeds have been produced from the following crosses: L. cicera × L. sativus (Saw Lwin*), L. clymenum × L. ochrus (Saw Lwin*), L. clymenum × L. articulatus—reciprocally (Davies), L. articulatus × L. ochrus (Davies), L. hirsutus × L. odoratus (McWhirter*), L. odoratus × L. hirsutus (Davies), L. sylvestris × L. latifolius (Ellis*).
