Pepper morphological traits related with resistance to Phytophthora capsici

摘要: Inheritance of 10 morphological and quantitative traits related to plant fruit development resistance the pathogen Phytophthora capsici was studied in an intraspecific cross between a non-pungent, susceptible Capsicum annuum parent (cv. Americano) wild, pungent resistant line (Serrano Criollo de Morelos-334). Data were obtained from segregation 166 F2 plants 50 F3 four years. Three analyzed (necrosis length, leaf width length) exhibited transgressive segregation. A multiple linear regression analysis applied order establish relationship necrosis length some measured such as leaf, diameter mass fruit, capsaicin content fruits, presence hair on leaves stems. The results identified dependence (as inverse measurement resistance) width, stem. Pungency not with resistance.
