Comparison of genotype × trait and genotype × yield-trait biplots in Sunflower cultivars

نویسندگان

چکیده

The selection of genotypes based on various characteristics is a critical challenge in plant breeding. An experiment was carried out randomized complete block design (RCBD) three replications over two crop years, 2018-2019, to compare the effects genotype × trait (GT) and yield-trait (GYT) methods as well investigate relationships between grain yield different agronomic traits. Plant materials ten sunflowers (Helianthus annuus L.) genotypes. Based combined analysis variance, there significant difference parameters except leaf length. effect year all traits height, stem diameter, length (P≤ 0.01). Gabur, Azargol Favorite were ranked years experiment. graphical performed (GT), Zaria selected best stable genotype. biplot by other desired levels depicts their profiles, or strengths weaknesses. correlation revealed positive correlations most with yield. This method pictorial, objective, effective, simple compared method. GYT technique paradigm shift that should be assessed combination variables rather than individually. Gabur Armavirski for investigated could recommended cultivation Karaj location.

Evaluation of Water Deficient Stress Tolerance in some Wheat Cultivars and Their Hybrids using Canonical Discriminant Analysis and Genotype by Trait Biplot

Canonical discriminant analysis (CDA) in combination with cluster analysis and genotype by trait (GT) biplot analysis methods were used to assess 9 wheat cultivars having different degrees of tolerance along with 36 F1 hybrids derived from partial diallel crosses, using stress tolerance indices, in two levels (well watered and cessation of irrigation at pollination stage). Cluster analysis clas...
