| Abstract:
Asian pears (e.g., Pyrus pyrifolia) are still little consumed in Brazil because for most consumers the good quality of the fruits is unknown and also because of the high selling price. Sensory analyses carried out in markets have shown great interest by consumers for this type of pear, but the planting area is small and all Asian pear cultivars currently planted are originated in countries where climatic conditions differ from those of Brazil. The low adaptation of Asian pears in Brazil has caused poor flowering, low productivity and production and deformed fruits. In order to mitigate these deficiencies, the Pear Breeding Program Epagri/Caçador Experimental Station launched in 2017 the ‘SCS421 Carolina’ cultivar, obtained in 1998 from the crossing ‘Housui’ × ‘Osa Nijisseiki’. Fruits with more symmetrical rounded shape compared to ‘Housui’, with golden brown color, medium size (220 g), good commercial appearance and organoleptic quality have been produced. This new cultivar is moderately resistant to entomosporiosis (Diplocarpon mespili). Evaluations have shown that there is good uniformity of size among fruits. In Brazil harvest occurs in the first half of February, nearly the same as ‘Housui’, its competitor. Fruit need to be bagged during development for best commercial appearance. | |
