Abstract


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.
