“…This crop has multiple uses, including as a source of protein (20%–25%) in the human diet, as a fodder for fuel and animal feed, as a cover crop fixing nitrogen in soils to improve their structure and fertility, and as medicinal uses (Rao et al., 2003; Vales et al., 2012). 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).…”

Pigeonpea [Cajanus cajan (L.) Mill.] breeding lines (BL) IIPG‐7 (Reg. no. GP‐326, PI 704909) and IIPG‐11 (Reg. no. GP‐327, PI 704910) were developed at the University of Puerto Rico. Both BL were bred to have indeterminate flowering habit and photoperiod insensitivity. The agronomic performance of IIPG‐7, IIPG‐11, and checks was tested during different growing seasons in Isabela and Lajas, Puerto Rico. IIPG‐7 and IIPG‐11 were early maturing and initiated flowering at 73–84 days after planting (DAP), reaching harvest maturity at 121–127 DAP. This was in comparison to indeterminate cultivars ‘Ariel’, ‘Blanco Yauco’, ‘Kaki’, ‘Pinto Berrocales’, and ‘Super Pinto’, which initiated flowering at 91–102 DAP, reaching maturity at 138–148 DAP in short‐day conditions that occurred in October in both locations. These cultivars had seed yield values of over 1000 kg ha−1, whereas IIPG‐7 and IIPG‐11 produced 721–1010 kg ha−1. In contrast, IIPG‐7 and IIPG‐11 were the only indeterminate genotypes that initiated flowering at 42–88 DAP and reached maturity at 88–172 DAP under long‐day conditions (February, March, and May) in both locations. Seed yields of IIPG‐7 and IIPG‐11 varied from 626 to 2449 kg ha−1 in Isabela and were close to 2000 kg ha−1 in Lajas. IIPG‐7 has tan seed with reddish spots; IIPG‐11 has reddish seed with an average weight of 14 and 15 g per 100 seeds, respectively. The IIPG‐7 and IIPG‐11 BL can be used directly by growers or breeders to develop pigeonpea cultivars that can be planted year‐round.

Pigeonpea [Cajanus cajan (L.) Mill.] cultivar 'Lázaro' (Reg no. CV-331, PI 692612) was developed in the United States at the Isabela and Lajas Research Substations at the University of Puerto Rico in collaboration with researchers at the University of California, Riverside. Lázaro was derived from the bi-parental cross '2B-Bushy'/OP-61 and traces back to the selection of F 2 individual plants insensitive to long daylength (>12 h) and advanced by a combination of pedigree and bulk breeding methods. Lázaro is photoperiod insensitive, and its yield performance was tested in six environments with checks in Puerto Rico and under furrow and drip irrigation systems in California in 2017 and 2018. Lázaro has a determinate growth habit, initiates flowering from 69 to 94 d, reaches harvesting maturity between 130 to 149 d, and has a small beige seed (17 g per 100 seeds). Mean seed yield varied from 338 to 1,091 kg ha −1 in Puerto Rico and >3,300 kg ha −1 in California. Furthermore, Lázaro can be planted year-round compared with cultivars 'Cortada', 'Guerrero', and 'ICP 7035', which are photoperiod sensitive and thus only recommended for planting under short-daylength conditions.
