Narrative
A castor plant with determinate growth, strictly annual, could be achieved through the suppression of secondary growth and/or of the branching. To achieve this long-term goal, the phenotypic recurrent selection method is in progress at the University of Pisa, Tuscany, Italy. By alternating, year after year, self-pollination with open-pollination, the percentage of unbranched dead plants increased to 46% over the course of 7 yrs. This population, named Rexel, is composed of plants with a green, waxy, non-dwarf stem, with medium compact racemes and spined capsules. It flowers about 30-40 days from emergence, the stem has about 13-17 nodes, the plants are about 100-200 cm tall, the racemes are about 30-50 cm long, the 1000-seed weight is about 250 g, the seed yield is calculated to be around 1,500-2,000 kg/ha, the oil conten­is about 38% and ricinoleic acid 94%. Those traits are not currently under selection, which instead continues exclusively to further increase the frequency of non-branched senescent plants after the ripening of the first and only raceme.

Pedigree
Description:
The program of Phenotypic Recurrent Selection started in 2014 mixing the seed of the following nine inbred lines to form the population of origin (CO): P87 # 287 A, P87 # 762vc, T87 #49 Hy1, P93#211, P93#335, P94#31-2, P94#44-15, R95#55-23, R95#79-19. The first three derived from a self-fertilization program without selection (Baldanzi et al., 2015) and the other six from a pedigree selection (Baldanzi & Pugliesi, 1998). In 2017, three more inbred line􀁔 were added: C86 # 4ii-bis, P87 # 762, and T87 # 220A 1 Hy. Self-pollination was carried out every other year: in 2015, 2018, and 2020. Open pollination was carried out in the years 2014 (CO), 2017, 2019, and 2021.
