Abstract—Large-seeded peanut varieties with high yield, early maturity and non-spreading growth habit are desirable for cropping systems in Thailand. The objective of this study was to evaluate newly-developed peanut breeding lines for large seed and early maturity in the East, Thailand. The study was conducted in two experiments. On farm experiments were laid out in randomized complete block design with six replications for both experiments. Data were recorded for above ground fresh and dry weight, number of pods, pod dry weight, number of seeds, seed weight, seed size (100-seed weight), shelling percentage and harvest index. In experiment I, (Luhua 11 x China 97-2) F6-11-4 was the best performer in breeding line group. It showed high 100-seed weight (64.3 g), high shelling percentage (58%) and high harvest index (0.55). In experiment II, (Luhua 11 x China 97-2) F5-13 and (Luhua 11 x KK 60-3) F5-11 revealed the greatest characters for 100-seed weight and harvest index. (Luhua 11 x China 97-2) F5-13 had 77.9 g and 0.59 of 100-seed weight and harvest index, respectively. (Luhua 11 x KK 60-3) F5-11 had 73.7 g and 0.58 of 100-seed weight and harvest index, respectively. Moreover, all breeding lines were early mature (110-115 days after planting). The results of this study would be useful to select the best peanut varieties for recommendation and release to Thai farmers.
