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. 

泰国东部大粒早熟花生高级育种品系评价

高产、早熟和不扩散生长习性的大种子花生品种是泰国种植系统的理想选择。本研究的目的是评价泰国东部地区新开发的大粒早熟花生育种品系。这项研究分为两个实验。农场试验采用随机完全区组设计，两个试验均设6个重复。记录地上鲜干重、荚果数、荚果干重、种子数、种子重、种子大小(百粒重)、脱壳率和收获指数。在试验一中，(鲁花11 ×中国97-2)F6-11-4是种系组中表现最好的品种。百粒重64.3 g，脱壳率58%，收获指数0.55。在试验II中，(鲁花11 ×中国97-2)F5-13和(鲁花11 × KK 60-3) F5-11在百粒重和收获指数上表现出最大的性状。(鲁花11 ×中国97-2)F5-13的百粒重和收获指数分别为77.9 g和0.59。(芦花11 × kk60 -3) F5-11百粒重73.7 g，收获指数0.58;所有选种均为早熟株系(播种后110 ~ 115 d)。本研究结果将为泰国农民选择推荐和推广的最佳花生品种提供参考。
