Genotype x environment interaction studies in Chenopodium album L.: an underutilized crop with promising potential

This study was carried out to evaluate the performance of different germplasm lines of Chenopodium album L. in successive foliage cuttings, as well as to study the magnitude and pattern of genotype × environment interaction for different morphological and quality traits. Thirteen germplasm lines of C. album were evaluated for three consecutive years at Lucknow, India. Data recorded was foliage yield and values for five morphological and three quality traits. Leaf protein among the lines ranged from 3.63-4.51 g 100g-1 with a mean of 4.06 g 100g-1, leaf carotenoids ranged from 0.98-1.40 mg g-1. Two diploid and four hexaploid lines had a high stability for foliage yield. Two germplasm lines of C. album CA-VI and CA-XI were the only lines, which showed stability for all quality traits. Lines CA-I, CA-VI and CA-XIII showed stability for foliage yield and were high yielding. This indicates the possibility of simultaneous selection for high yield and broad adaptation.
