Evaluación agronómica de 15 genotipos de gandul [Cajanus cajan (L.) Millsp.] en Isabela y Lajas, Puerto Rico

Abstract: El gandul [Cajanus cajan (L.) Mills.] es una fuente importante de proteína en la dieta humana. En Puerto Rico, se han desarrollado genotipos de crecimiento determinado e insensitivos al fotoperiodo, sin embargo, supotencial productivo necesita ser evaluado. El objetivo de la presente investigación fue realizar la evaluación agronómica de 15 genotipos de gandul en Isabela y Lajas en el 2017 y 2018. Se registraron variablescuantitativas [e.g., días a floración y cosecha, rendimiento (t/ha), entre otras] y cualit… Show more

“…This genotype is insensitive to the photoperiod, has determinate upright growth habit, possesses flowers with petals of yellow color, and has early maturity (< 135 d after planting) in field evaluations in Puerto Rico (Viteri, personal communication). 'L azaro' has determinate bushy-type growth habit, possesses flowers with petals of red colors on the outside and yellow on the inside, and reaches harvesting maturity between 130 to 149 d after planting (Sarmiento et al 2021;Viteri et al 2020). Twenty F 1 plants with red colored petal flowers (a dominant trait derived from 'L azaro' to identify hybrids) were selected and harvested in Sep 2019 at the Isabela Research Substation, University of Puerto Rico.…”

“…one of the most important legumes for human consumption in Puerto Rico (Sarmiento et al 2021), the Caribbean basin, and various countries in Africa and Asia (Fuller et al 2019;Ojwang et al 2016;Snapp et al 2003). The pigeonpea production in Puerto Rico was 146,147 kg with an economic contribution of $434,000 in 2017 (Puerto Rico Department of Agriculture, 2017).…”

“…In Puerto Rico, pigeonpea is one of the most important legumes (Morales et al., 1988; Viteri et al., 2020). It is harvested and consumed as immature seed (Hepperly & Díaz, 1983), with a peak of consumption during the Thanksgiving, Christmas, and New Year holidays (Sarmiento et al., 2021; Viteri et al., 2020). The economic contribution of pigeonpea was estimated to be $434,000 in 2017 (Puerto Rico Department of Agriculture, 2017).…”

“…In contrast, and to the best of our knowledge, there are no germplasms or cultivars with both traits that have been released in the Caribbean basin. All local cultivars with indeterminate flowering habit planted in Puerto Rico (e.g., ‘Ariel’, ‘Blanco Yauco’, ‘Guerrero’, ‘Pinto Berrocales’, ‘Pinto Original’, and ‘Super Pinto’) (Bosques‐Vega et al., 2000; Sarmiento et al., 2021; D. M. Viteri & R. Vázquez, personal communication, 2022) are photoperiod sensitive. This means that, when plants are exposed to long‐day conditions (>12 h), and generally planted between February and July), they do not initiate flowering until short‐day conditions (<12 h) occur.…”
