Resistance in Temanggung tobacco lines to tobacco aphid (Myzus persicae Sulzer)The evaluation on the esistance of Temanggung obacco lines against tobacco aphid was carried out in Malang, from August 19% to March 1997. The experiments consisted of antixenosis and antibiosis resistance. The teatments wee four tobacco lines fom the original population: (1) S.2258, (2) S.2132, (3) S.l%3, (4) S.1965; four lines rom selected population: (5) S.2258/2/1/1, (6) S.2132/2/2/1/1, (7) S.1%3/3/2/1/2/1, (8) S.1%5/2/1/2/1/1; one local line: (9) Kemloko (Gober genjah); two varieties resistant and susceptible o tobacco aphid: (10) Coker 176, and (11) NC95. The treatments wee arranged in randomized block design, with three replications. The esults showed that the two lines from the selection evaluation: S.2258/2/1/1 and S.1%3/3/2/1/2/1 wee resistant to tobacco aphid. Both lines had high density of leaf trichomes, and can be used as resistant resources in plant breeding activities.
