Interaksi Genotipe - Lingkungan Pada 7 Genetipe Tembakau Besuki Na-Oogst

Abstract

Seven tobacco Besuki na-oogst genotypes were tested in 5 environments to study their stability. A randomized block design with 3 replications and 120 plants/plot was used in each environment. Regression of GE on E for plant height, maturity and number of leaves was carried out to study the stability of these genotypes. The result indicated that K103 is the least stable in respect to plant height and number of leaves; with b = -0.40 and R.2 = 83% for plant height and b = -0.38 and R.2 = 96% for number of leaves, H343 with b = 0.48and R.2 = 60% and H892 with b = 0.19 and R.2 = 78% are the least and the most reliable genotypes in respec to plant maturity, respectively.
