Genetic variability in vegetable Chenopodium for morphological and quality traits over different cuttings
Abstract The present study was performed to assess the genetic parameters for different quantitative and qualitative traits of 13 germplasm lines of Chenopodium spp. The lines were sown in a randomized block design with a plot size of 2 m2, and data were recorded for foliage yield and 8 component tr...

The foliage yield/plot was variable, ranging from 1.07-2.66 t ha-1 with an average yield of 2.00±0.15. The protein and carotenoid contents averaged 3.70±0.09% and 13.47±0.56 mg 100 g-1, respectively.

High heritability estimates for all the traits under study were obtained for individual cuttings as well as on a pooled basis. High heritability coupled with high genetic gain was observed for foliage yield, carotenoid content and protein content, indicating the presence of additive gene effects.info:eu-repo/semantics/openAccessPontificia Universidad Católica de Chile.
