Registration of 'Retaca' faba bean.

'Retaca' faba bean (Vicia faba L.) (Reg. no. CV-224, PI 633759) (Reg. INI A990180) was developed by the Plant Breeding and Agronomy Department of Centro de Investigacion y Formacion Agraria (CIFA) (Junta de Andalucia) in cooperation with the Genetic Department of the University of Cordoba, Spain, and released in 2001.

'Retaca' has a determinate growth habit and was developed specifically for the canning and freezing industry as well as for direct use as both fresh green pods and grain. The main benefit of the determinate growth habit of this cultivar is the ease of harvesting since erect pods are concentrated at the top of the stems, and mature at the same time. Retaca originated as an [F.sub.9] selection from the cross between 'Alameda' (an indeterminate growth habit cultivar well adapted to the local environment) and a mutant ti (Sj0din, 1971) from ICARDA (pedigree: FLIP 86-144FB; ILB cross no. D83032). The cross was made in 1994 and a pedigree selection program, under insect-proof cages, was used to combine determinate growth habit, erect pods, sweet young green grains, and good adaptation. Seed multiplication was also performed under insect-proof cages. The breeding program was realized at Cordoba (southern Spain; Mediterranean subtropical climate).

The number of nodes bearing inflorescences and mature pods on the main stem is four and three, respectively. The average number of pods and grains per plant is 11 and 26, respectively. Pod length and number of seeds per pods averaged 8 cm and three, respectively. Retaca has an average seed length, width, and thickness of 1.8, 1.2, and 0.6 cm, respectively. The weight of 1000 seeds is 962 g.

Retaca is susceptible to broomrape (Orobanche crenata Forssk.) infection but escapes damage from the early harvesting of green pods when broomrape shoots are starting to emerge. In addition, Retaca tolerates higher glyphosate rates for control of broomrape than standard cultivars (Nadal et al., 2001), which enables broomrape control during seed production when heavy broomrape infection is expected. Row spacing and seeding rate trials show that 30 cm between row spacing and 10 cm spacing between plants in the row resulted in higher yields of young green pods for canning.

Breeder seed of Retaca is maintained by Legumes Group of Centro de lnvestigaci6n y Formaci6n Agraria (CIFA) of C6rdoba, Spain. Small samples for breeding purposes are available from the senior author. Plant variety protection will not be sought for this cultivar.
