Registration of photoperiod insensitive pigeonpea cultivar 'Lázaro'.

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 F2 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.
