Caracterització morfoagronòmica de Phaseolus vulgaris, L. Producció

The snap bean (Phaseolus vulgaris L.) has, depending on growth type, determined (bush type) o undetermined (climbing type). The growth type greatly influences the production cost, as bush type need much less work to install (props are not needed) and the crop iseasier to manage (phytosanitary treatments are easier to apply). Nowadays, farmers from the Maresme zone have valuable varieties form an agronomic and sensory point of view, but these varieties are of undetermined growth. For this reason, a breeding programme was launched to obtain a variety of determined growth with the same sensory characteristics of the best variety of undeterminate growth variety, along with an acceptable production. This Final Degree Project is a part of this general project. The work here presented consists on a generation of selection within the general pedigree selection program on course. In particular, during the 2016 spring-summer seasons S3 plants coming from crosses between determined and undetermined type of growth plants were evaluated in field trials. The traits recorded included from yield to plant architecture, and its combined consideration allowed identifying the best families and plants within family for agromorphologyc and productive traits. During the experiment it has also been proved that in this S3 generation, as expected, all plants had the gene fin in homozygosis, as no climbing plants appeared in the field trials. The seeds obtained by selfing (self-fertilization) of the selected plants (93.75% loci homozygous in average) will be the base for the next generation of selection. La mongeta tendra (Phaseolus vulgaris L.) presenta, segons la varietat, creixement determinat (mata baixa) o indeterminat (mata alta). El tipus de creixement fa variar molt els costos de producció, ja que les varietats de mata baixa requereixen molta menys feina d'instal·lació (no s'han de posar tutors) i el cultiu és més senzill de gestionar (els tractaments fitosanitaris es fan amb més facilitat). Actualment els agricultors de la zona del Maresme disposen de varietats de gran valor agronòmic i sensorial però de creixement indeterminat. Per aquest motiu es va iniciar el projecte de millora, en el qual està inserit aquest treball de grau. El seu objectiu general era obtenir una varietat de creixement determinat que tingués les mateixes característiques sensorials que la millor varietat de creixement indeterminat, juntament amb una producció acceptable.
