A study of peaberry development: its implications in coffee breeding
Peaberry development in the parents and progenies of Devamachy hybrids (Selection-5) of coffee has been studied. It is elucidated that the development of peaberry is associated with the availability of space in the ovary due to the pre-fertilization abortion of one of the two ovules. Empty locule formation is found to be due to the post-fertilization abnormalities. A breeding scheme to evolve lines with reduced peaberry and empty locule production is suggested on the basis of the data presented. This involves the selection of individual plants with low peaberry production and high self-compatibility from the F2 progeny and further testing for fertility and adaptability
