Júpiter-INIA is a new oat (
Avena sativa
L.) cultivar
selected in preliminary field trials for higher β-glucan
and protein content, resistance to disease and lodging,
and similar yield than the other cultivated oat varieties.
The objective of the present research was to compare
agronomic, industrial performance and groat nutritional
quality of ‘Júpiter-INIA’ with the widespread commercial
‘Supernova-INIA’ in southern Chile. Field trials were
conducted at four different locations during four seasons
in a randomized complete block design with three
replicates. ‘Júpiter-INIA’ had about 20% more β-glucan
(4.25
vs. 3.31 g 100 g
-1,
P < 0.0001) and protein (16.14
vs. 12.78 g 100 g
-1,
P < 0.0001) contents than ‘Supernova-
INIA’. The overall plant height, lodging, and disease
reaction to crown rust were lower in ‘Júpiter-INIA’ than
in ‘Supernova-INIA’. Grain yield, 1000-grain weight,
and hectoliter weight, were lower in ‘Júpiter-INIA’ than
in ‘Supernova-INIA’; however, its mean values were
within the range for oat cultivars. Dehulled-grain yield
and stained grains were similar to ‘Supernova-INIA’. This
results point out that ‘Júpiter-INIA’ groat had superior
nutritional quality than ‘Supernova-INIA’, and thus it
could be an important contribution to be included in the
development of healthy oats-containing food products.
