This study was carried out in Shanxi province from 1983 till 1985. The results are summarized as follow:The values of two yield stability parameters among some hybrids of maize were considerably different in the regional test of the same year; those of the two yield stability parameters of the other hybrids were either significantly or not significantly different in the regional tests for different years, showing that in different years, under different climate and environmental conditions, these hybrids have...

This study was carried out in Shanxi province from 1983 till 1985. The results are summarized as follow:The values of two yield stability parameters among some hybrids of maize were considerably different in the regional test of the same year; those of the two yield stability parameters of the other hybrids were either significantly or not significantly different in the regional tests for different years, showing that in different years, under different climate and environmental conditions, these hybrids have different yield stabilities and adaptabilities. The experiment proves that only after the regional test, for three consecutive years can the yield stability of new hybrids be more precisely evaluated.This experiment suggests that the correlation coefficients between mean, yields and stability parameters were nonsignificant (rx-·b = 0.0612, r-x ·r2 = -0.2933 ) . The hybrid yield stability was found associated with the changes of the major agronomic characteristics, especially of the ear characterestics. Among these hybrids, Tai Dan Zao N0.3 was found in the three-year regional test to be a high-yield, stable, and widely adaptable species.This analysis method seems to be an effective tool for breeders to use in studying varietal yield stability and adaptability in the crop variety regional test

在同一年份区试中,玉米杂种间两种稳产性参数有相当大的差异;在不同年份区试中,有的杂交种两种稳产性参数无明显差异,有的则差异很大,说明这些杂交种在不同年份、气候和环境条件下有不同的稳产性和适应性.杂交种通过连续三年区试之后,才能更好的评价其稳产性.杂交种的平均产量与其稳产性参数间的相关系数不显著(r(?)=0.0612,r(?)=-0.2933).杂交种稳产性与主要农艺性状特别是果穗性状变化相关联.在作物品种区域化试验中,这一分析方法似乎是育种工作者研究品种产量稳定性和适应性的一个有效工具.

Variety regional evaluation aimed at comparing the productions of forage grass varieties selected and grown in different regions, and then, the adapted cultivating regions and the extending value for tested Varieties were determined. In this paper, taking long-term and different regional evaluation of rye strains for instance, the analysis method on calculating the mean grass production (X) and the coefficient of variation(C.V) of interaction between the strains and the enviroments is recommended. By this method,...

Variety regional evaluation aimed at comparing the productions of forage grass varieties selected and grown in different regions, and then, the adapted cultivating regions and the extending value for tested Varieties were determined. In this paper, taking long-term and different regional evaluation of rye strains for instance, the analysis method on calculating the mean grass production (X) and the coefficient of variation(C.V) of interaction between the strains and the enviroments is recommended. By this method, the high production and the stablity on the varieties in regional evaluation can be carried out. So this method is optimized approach in carrying out analysis of variety regional evaluation.

品种区域试验就是比较参试品种在不同地区的产量高低,最后确定品种(系)有无推广价值和适宜的推广范围。本文以黑麦草品种的多年多点试验为例,介绍一种计算平均产量(X)和品种与环境互作的变异系数(C. V)的分析方法。此方法可对区域品种试验的丰产性和稳定性进行评价,是品种区域试验分析的极优方法。

During the 1990 cotton variety regional test,a supplementary test was carried out to try the effect of DPC (1,1-dimethylpiperidium chloride)on the entry cultivars. Although interacting effects between DPC treatment and cultivars were observed in several indexes, the varietal effect still predominated; the positions of the three highest yielding entries in the order of their lint yields were not changed by the DPC treatment,and the fiber qualities were not influenced markedly. Thus ,it is feasible to apply...

During the 1990 cotton variety regional test,a supplementary test was carried out to try the effect of DPC (1,1-dimethylpiperidium chloride)on the entry cultivars. Although interacting effects between DPC treatment and cultivars were observed in several indexes, the varietal effect still predominated; the positions of the three highest yielding entries in the order of their lint yields were not changed by the DPC treatment,and the fiber qualities were not influenced markedly. Thus ,it is feasible to apply DPC of an adequate dosage in cotton regional tests for the Yangtze valley area when rank growth of cotton plants is likely to occur , so as to make the trial conditions closer to commercial production.

对棉花品种区域试验的参试品种同步进行化学调控试验表明,化调与品种在多项指标上存在互作效应,但未改变增产品种原有的位次,对品种的内在品质也无明显影响,品种效应仍占主导地位。因此,在长江流域棉区蕾花期旺长的情况下,一次定量喷施生长调节剂,对提高区试试验质量是可行的。
