The factor pair Ee for normal vs. long outer glume (IO) :~ was studied by Bose, et al. (1). 3 They found a linkage of normal vs. long outer glume and non-six-row vs. six-row. The recombination value was 24.7%. The awnless vs. awned factor pair (Lk Ik) (Io) was described by Engledow (3) who found its expression to markedly influenced by environment. He concluded in another paper (4) that, "the character ’six-row’ and the character ’full awns’ are governed by separate but highly linked factors." Myler (8) found two factor pairs, Lk lk and Lk, lk,, differentiating awn types in crosses between Awnless (C.I. 5631) and several different awned varieties. Leonard (7) found another factor pair Lr lr for presence vs. absence of appendages on the lemma of the lateral fiorets to be linked with Or or, a factor pair from green vs. orange seedlings, with a recombination value of 38.58 41.2o%. Four other factor pairs (9, lO) have previously been located in Group I, namely, Vv for non-six-row vs. six-row and Ff for green vs. chlorina plant color, Or or for green vs. orange seedlings and Yy for green vs. virescent seedlings.
