摘要
利用DPS数据处理系统对2011、2012年全国(长江片)花生区域试验资料进行丰产性和稳定性分析。结果表明,2011、2012年泉花551区试荚果产量分别为4699.5、5086.5 kg·hm-2,分别居参试品种的第2位和第1位,比中花15(CK)分别增产7.17%和13.12%,均达极显著水平;荚果产量主效应分别为0.26和0.50,说明该品种丰产性好;回归系数分别为1.1953和0.9596,说明对环境反应不敏感;高稳系数分别为71.53%和80.17%,说明该品种稳定性较好;由品种×地点互作效应值可以看出,泉花551适宜在长江中下游大部分地区推广种植。
The author analyzed yielding ability and stability based on experimental material of peanut region in the nation （ the Yan- gtze River） in 2011 and 2012 which was handled by data processing system DPS. The restdt showed five aspects. Firstly, pod yield in Quanhua 551 area were 4699.5 kg · hm-2 and 5086.5 kg · hm-2 respectively in 2011 and 2012 and took the second and first po- sition in tested varieties within the years. What is more, these two pod yields were 7.17% and 13.12% significantly higher than control Zhonghua 15. Secondly, the main effects of pod yield were 0.26 and 0.50 respectively, which showed that this species got good yielding ability. Thirdly, regression coefficients were 1.1953 and 0.9596 respectively; which meant that this species was not sensitive to the environment. Fourthly, high stability coefficients were 71.53% and 80.17% respectively, which indicated that this species got good stability. Lastly, it was found from interaction effect values of variety plus location that Quanhua 551 was suitable for promoting to he planted in the majority part of the middle and lower reaches of the Yangtze River.
