Genética de Coffea: XXVI. Hereditariedade do porte reduzido do cultivar Caturra

Abstract: A mutação de Coffea arabica, conhecida sob a denominação de Caturra, caracteriza-se pela redução do comprimento médio dos internódios dos ramos ortotrópicos e plagiotrópicos, o que diminui a altura das plantas, conferindo-lhes um aspecto compacto. Surgiu provavelmente no Bourbon Vermelho, e sua produção se assemelha à deste cultivar. Devido a suas características, a densidade de plantio poderá ser aumentada, refletindo favoravelmente na produçãc por área, e facilitando tanto a colheita como os tratos culturais… Show more

“…The hybridization had the objective of combining complementary agronomic traits of the parents in a new cultivar. The coffee tree H 2077-2-5-46 has a compact architecture, with short internodes on both the orthotropic stem and plagiotropic branches, due to the homozygous expression of the allele caturra (Carvalho et al 1984); but highly productive, and susceptible to coffee leaf rust. On the other hand, IAC 1110-8, a single plant of selection BA10, is highly resistant to this disease.…”

“…In spite of small variations in the height and canopy diameter, the four clones exhibited dwarf size, suggesting that their mother plants have at least one Ct allele, once the characteristic is controlled by expression of a dominant gene named caturra (Carvalho et al 1984).…”

“…Information on genetic control of the compact size of the plants was concluded only after the release of 'Catuaí' (Carvalho et al 1984). The trait is monogenic and the dominant allele Ct is responsible for the low plant size ('Caturra').…”
