Table 1 Deviance analyses and the χ2 test, estimates of variance components, means, heritability, selective accuracy, coefficient of variation, and genotypic correlation among experiments for HL (Harvest L*), L30 (L* after 30 days) and ΔL* (Delta L*) traits evaluated in the 138 carioca bean genotypes from the carioca diversity panel (CDP) during the years 2018 and 2020

  1. HL: lightness (L*) of the seed coat at harvest; L30: lightness (L*) of the seed coat after 30 days of storage; ΔL: difference in final lightness (L30) and initial lightness (HL), h2: broad-sense heritability; Rgyear: genotypic correlation between years; CV: coefficient of variation
  2. a Significant at 1% by the χ2 test
