Inheritance of pseudostem waxiness in banana and plantain (Musa spp.)
Article Abstract:
Bananas and plantains are found in abundance in tropical regions. Triploid bananas and plantains are made from hybridization between the diploid Musa species M. acuminata with the A genome and M. balbisiana with the B genome. Epicuticular wax is found on the leaf surface of some bananas and plantains and is the best defense against black sigatoka leaf spot disease. An attempt to breed for the epicuticular wax determined that phenotypic recurrent selection was the best hybridization method.

Cytology of 2n pollen formation in a blueberry aneuploid (2n = 4x + 9 = 57)
Article Abstract:
A study was done on the mode of 2n pollen formation in an aneuploid using a derivative from Vaccinium ashei. It was shown that 2n pollen formation results from desynapsis of paired chromosomes prior to metaphase one, sister centromere disjunction in univalents at anaphase one and cytokinesis after telophase one leading to dyad formation. Furthermore, it was shown that heterozygosity transmission approximates first-division restitution 2n gametes.

Estimation of 2n megagemetophyte heterozygosity in a diploid blueberry (Vaccinium darrowi Camp) clone using RAPDs
Article Abstract:
A study designed to determine the mode of 2n gamete formation and to estimate heterozygosity transmission in a diploid blueberry clone is presented. The level of heterozygosity suggests that a first division restitution mechanism of 2n megagametogenesis is evident, while second division restitution mechanisms also operate.
