Abstract


The stability of yield and quality of the new lines of Temanggung tobacco

The productivity of Temanggung tobacco is relatively low. One of the causes of the low productivity is genetic deterioration. Fom a series of selection, four lines were potential to be developed. Befoe the new varieties are released they need to be tested at different locations in a central poducing area. The tests were conducted at 1 1 locations in Temanggung District rom 1995 to 1997. The lines tested included four selected lines, original population of Temanggung tobacco.from which the selected lines were produced, and Kemloko, a local variety generally planted by farmers. The trial, were designed as a randomized block in three replicates for respective location. Results showed that two of four tested lines i.e. 2258/2/1/1 and 2132/2/2/1/1 produced stable yield and quality. Compared with Kemloko (local variety) the dry sliced tobacco, grade index and crop index of 2258/2/1/1 increased by 17.57, 6.85, and 26.88% respectively and those of 2132/2/2/1/1 increased by 12.28, 16.03, and 31.88% respectively.
