PENALOZA, Enrique; TAY U, Juan  and  FRANCE I, Andrés. Calpún-INIA, a large seed size and rust-resistant lentil (Lens culinaris Medik.) cultivar. Agric. Téc. [online]. 2007, vol.67, n.1, pp.68-71. ISSN 0365-2807.

Calpún-INIA is a rust (Uromyces fabae Pers.) resistant lentil (Lens culinaris Medik.) cultivar that was developed by the former Food Legume Program of the National Institute of Agricultural Research (INIA), Chile. It is derived from crosses between the Chilean rust-susceptible Araucana-INIA and the Canadian rust-resistant Laird cultivars, using earliness, Araucana-INIA’s type of plant architecture, seed size, seed yield and rust resistance as selection criteria. Calpún-INIA belongs to the large seeded cultivars (macrosperma type), averaging 8 g per 100 seeds, and > 65% of seeds retained in a 7 mm sieve. The seed is partially flattened, with pale green to grey background and pale yellow cotyledons. Averaged across years, the seed yield of Calpún-INIA was 17% lower than Araucana-INIA’s in rust-free environments, whereas Calpún-INIA out-yielded Araucana-INIA by 60 to 95% in environments where this disease is the main constraint for lentil production. Calpún-INIA is the first lentil cultivar released by INIA, combining high yield and large seed size with rust resistance.
