GREEN SEED COAT COLOUR RETENTION IN LENTIL - University ...

was a=0.05. The heritability was calculated from the ANOVA of the RILs. The
heritability estimate is broad sense as the RILs were not at complete homozygosity.
They are approximately 99.2 percent homozygous at F7. The calculation of
heritability is described by Falconer and MacKay (1996):
H 2 = s 2 genetic / s 2 phenotypic , (4.2)
H 2 = broad sense heritability,
s 2 phenotypic = s 2 g + s 2 gl/l + s 2 gy/y + s 2 gly/ly + s 2 residual/rly,
g = genotype,
y = year,
l = location and,
r = block.
4.2.2 Chlorophyll Extractions
Chlorophyll extractions were performed on selected genotypes from a range
of index scores and locations from the heritability study. Genotypes with an index
score range of 2.40 to 8.62 were used (Table 4.5) to cover a large range from high
quality green seed coats to those exhibiting bleaching and oxidation, in each sample
used some seeds would have individually had lower index scores and some higher
index scores. This range was used so that most of the seed could be sourced from
one site.
