Diallel Anaysis of Oil Production Components in Peanut (Arachis hypogaea L.)

Table 2

Griffing’s analyses of variance and narrow-sense heritability estimates (ℎ²) for oil concentration in g kg⁻¹, weight of 50 sound mature kernels (50 SMK) in grams, and mean milligrams oil produced per SMK (OPS) in a four-parent 𝐹₂ diallel of peanut.
