Introducción: Obtener cultivares con alto potencial de rendimiento (RG) y buena estabilidad frente a déficit hídricos es fundamental para sostener e incrementar la producción regional de este cereal. El objetivo de este trabajo fue evaluar el comportamiento de cultivares de trigo caracterizados como diferentes en su tolerancia a déficit hídrico durante la etapa post-floración en un amplio rango de ambientes.
Conclusiones: Estos resultados aportan una nueva caracterización genotípica y destacan a INIA DON ALBERTO como material con muy buen comportamiento, a diferencia de trabajos previos donde se había caracterizado como de comportamiento intermedio. El estudio de la ocurrencia puntual del déficit hídrico en los ambientes evaluados y de otras características ecofisiologicas ayudaría a comprender las bases de la estabilidad de este cultivar a los estreses abióticos. |

A b s t r a c t:
The objective of this study was to determine how the social competition for an oestrous ewe affects the
sexual behaviour and the endocrine response in two groups of rams, one reared by their mothers and
another artificially reared. Thus, we compared the sexual behaviour and testosterone and cortisol
changes in each group of rams in competitive and non-competitive tests, both during the first and second
breeding seasons. Two groups of rams were: 1) artificially reared lambs, separated from their dams 24
e36 h after birth (Week 0) and artificially fed with sheep milk until 10 weeks of age (group AR, n ¼ 14);
and 2) lambs reared by their dams until 10 weeks of age (group DR, n ¼ 13). Rams were subjected to noncompetitive
and competitive tests for an oestrous ewe during their first and second breeding seasons,
when they were 8 and 20 months old, respectively. Sexual behaviours toward an oestrous ewe were
recorded during 20 min and the testosterone and cortisol concentrations were determined in serum
samples collected immediately before the test, and 20, 40 and 60 min after it. During the first breeding
season, the number of flehmen decreased in DR rams, and the number of flehmen and ano-genital
sniffings also decreased in DR rams, but the frequency of some copulatory behaviours increased (matings
and ejaculation/total mounts in DR rams, and total mounts in AR rams) in competitive tests. During
the second breeding season, competition caused a decrease in the number of all the recorded behaviours
(courtship and copulation) with the exception of flehmen in AR rams; however, in DR rams only the
number of the copulatory behaviours decreased under competition. Competition did not affect the
endocrine response during the first breeding season. During the second breeding season, while testosterone
concentrations were greater in non-competitive than in competitive tests at 60 min (P ¼ 0.0008)
in AR rams, in DR rams it tended to be greater (P ¼ 0.09). Competition did not affect cortisol concentrations
in any group or season, but in all tests the concentrations increased at the end of the test
(P < 0.05). In conclusion, the lack of the mother during rearing negatively affected the sexual motivation
and the testosterone response of rams to oestrous ewes in competitive tests, effects that were more
evident when adults. Neither the absence of the mother during rearing nor competition for oestrous
ewes affected the stress response (evidenced by increase in cortisol concentration) in rams during both
seasons. MenosA b s t r a c t:
