引言已知各种作物品种在不同环境下的稳定性一般是不同的.一个理想品种应集高产和稳定性为一体.1966年Eberhart等人提出了一个研究品种在各种环境下稳定性的统计模式以来,这一模式已在许多作物上得到运用,但所有这方面的研究只涉及纯系品种或纯系品种的杂交组合.关于混系品种及其相应的轮回亲本的稳定性研究资料还很有限.印度旁遮普农业大学(位于印度旁遮普邦的卢迪亚纳)已选育出两个广泛种植品种Kalyansona和PV-18的混系.本文报道了Kalyansona、PV-18及其若干混系的多年多地点的稳定性分析结果.
INTRODUCTION It is known that the stability of various crop varieties is generally different under different environments. An ideal variety should be a combination of high yield and stability. In 1966 Eberhart et al. Proposed a statistical study of the stability of varieties in various environments Since this model has been applied in many crops, all studies in this area have dealt only with hybrid combinations of pure lines or pure lines, and the stability of mixed lines and their corresponding recurrent parents is still very limited Limited. The crosses between two widely planted Kalyansona and PV-18 breeds have been bred in Punjab Agricultural University of India (Ludhiana, Punjab, India). This paper reports the prevalence of Kalyansona, PV-18, Location of the stability analysis results.
