【摘要】：运用联合方差和AMMI模型对11个胡麻新品系在6个地点的产量、株高、工艺长度、分枝数、单株果数、每果粒数、千粒质量和单株生产力的表现及稳定性进行研究。结果表明:环境及环境和基因型互作效应对胡麻主要农艺性状有显著影响且对各农艺性状影响的大小不同。对产量影响的大小为环境交互作用基因型;对株高的影响:环境基因型交互作用;对工艺长度的影响:环境基因型交互作用;对分枝数的影响:环境交互作用基因型;对单株果数的影响:交互作用环境基因型;对每果粒数的影响:交互作用环境基因型;对千粒质量的影响:环境交互作用基因型;对单株生产力的影响:环境交互作用基因型。通过稳定性参数可以看出,‘0569-14’产量稳定性最好;‘2004M1-15-1-1-1’的株高和工艺长度稳定性最好;‘0559-15’的分枝数、单株果数和单株生产力稳定性最好;‘1S×外6’的每果粒数稳定性最好;‘113×81A350’的千粒质量稳定性最好。
[Abstract]:The yield, plant height, process length, branching number, fruit number per plant, seed number per fruit, thousand kernel weight and productivity per plant of 11 new linseed lines in 6 locations were studied by combined variance and AMMI model. The results showed that the environment and the interaction between environment and genotype had significant effects on the main agronomic characters of flax and had different effects on the agronomic characters. The effect on yield was environmental interaction genotype, plant height effect: environment genotype interaction, process length effect: environmental genotype interaction, branch number effect: environmental interaction genotype; Effects on fruit number per plant: interaction environment genotype; effect on fruit number per fruit: interaction environment genotype; effect on thousand seed quality: environmental interaction genotype; effect on individual plant productivity: environmental interaction genotype. According to the stability parameters, it can be seen that the plant height and the process length stability of the yield stability are the best, the number of branches per plant and the number of fruit per plant and the productivity per plant are the best. The stability of seed number per fruit of 1 S 脳 6 'fruit is the best, and the stability of thousand seeds of 113 脳 81A 350' is the best.
