| چکیده فارسی مقاله |
To evaluate the salinity tolerance of sugar beet genotypes using tolerance indices and also to identify the best tolerance indices, full-sib families along with control cultivars were studied in separate experiments at Miandoab Agricultural and Natural Resources Research Station, West Azerbaijan, under salinity and control conditions. Analysis of variance showed that salinity stress reduced root and sugar yield. Weak correlations in root and sugar yield were observed under both normal and stress conditions. GMP, MP, and STI indices had a significant positive correlation with both root yield and sugar yield under both normal and saline stress conditions. The principal component analysis applied to both yield traits displayed that the first component had a high positive relationship with Ys and RSI, YI, YSI, and SI and a high negative relationship with YP, SSI, TOL, ATI, and SSPI. The second component showed a positive relationship with Yp, Ys, MP, GMP, YI, ATI, SSPI, and SNPI for both traits. The plot of components showed that genotypes 14, 6, 5, 4, 3, and 11 were the best ones for root yield, while genotypes 1, 3, 6, and 14 were the best ones for sugar yield, respectively. It seems that the MP, GMP, and STI indices can better distinguish the group A genotypes from the others. Also, for both yield traits, full sibs 1, 3, and 6 showed higher yield in both normal and saline environments. |
