基于灰色系统的辣椒新组合配合力综合评判

为在辣椒杂交育种中提高亲本配合力，本文运用灰色系统理论模型，对4个辣椒新组合34(55)×32(23)、34(55)×48(30)、34(55)×33(24)、34(55)×46-1]及理想品种进行了一般配合力的综合评判。结果表明，以34(55)×33(24)组合的经济性状最佳，各项性状指标与理想品种最为接近，其单果重明显高于其他组合；超双亲平均优势为22.0%，杂种优势指数为122.0%，符合辣椒新品种选育目标。

Comprehensive Evaluation of the Combining Ability of New Capsicum Combinations by the Grey System Theory

Toimprove the parental combining ability in capsicum cross breeding. The grey system theory model was used in this study to comprehensively evaluate the general combining ability of four new capsicum combinations 34 (55) × 32 (23), 34 (55) × 48 (30), 34 (55) × 33 (24) and 34 (55) × 46-1 and ideal varieties. Results showed that 34(55) × 33(24) had the best economic traits, and the traits were the closest to the ideal varieties. The single fruit weight was significantly higher than that of other combinations. The average heterosis of super parents was 22.0%, and the heterosis index of F1 was 122.0%, which were in line with the breeding objectives of new capsicum varieties.
