用两年四川省玉米山区组区域试验资料,采用Eberhart-Russell模型及高稳系数法,对川单15号的丰产性和稳产性进行综合评定。结果表明,川单15号的丰产性突出,区试平均产量高达458.8 kg/667 m2,比对照增产21.1%。bi和S2d i分析表明其稳产性较好,两年HSCi分别高达88.6和92.4,年度间稳定一致,证明川单15号属高产稳产型品种。川单15号的适应性强,适宜种植范围广,环境指数在300~600 kg/667 m2之间,都比对照有较显著的增产效果,其优势推广区域为生产水平为400~600 kg/667 m2的丘陵山区,将更能充分发挥其增产增收潜力。
Based on the regional experiment data of maize mountainous area in Sichuan province for two years, the Eberhart-Russell model and high-stable coefficient method were used to evaluate the comprehensive yield and stability of Chuan-Dan 15. The results showed that the high yield of Chuan Dan 15 was outstanding with the average yield of 458.8 kg / 667 m2 in the district test, which increased by 21.1% compared with the control. bi and S2d i analysis showed that its stability is good, the HSCi in two years are as high as 88.6 and 92.4 respectively, which is consistent in the year. It proves that Chuan Dan 15 is a high and stable yielding variety. Chuan Dan 15 was more adaptable, suitable for planting a wide range of environmental index of 300 ~ 600 kg / 667 m2, compared with the control have a significant increase in yield, the advantage of the promotion of the region for the production level of 400 ~ 600 kg / 667 m2 hilly area, will be able to give full play to their potential yield increase.
