Abstract

Eleven varieties of abaca (Musa textilis Nee.), three other Musa species (Musa balbisiana, Musa basjoo, Musa acuminate) and canton of the Abaca Gene Bank of the College of Agriculture, U. P., college Laguna were studied from July to October, 1971, for complete morphological description and cultivar classification using gross morphological characters.

A system for classification was made using these characters as parameter color of pseudostem, surface covering of pseudostem, condition of outermost, leafsheat, height of pseudostem, base circumference, shape of mature fruits, angle of distention of fruits bunch, density of bunch, number of handle per bunch, number od seeds per fruit, shape of male bud in advance blooming, surface of male bud, arrangement of male bracts, color of male bracts, number of male flowers per bract, position of leaf base, shape of leaf blade, color, leaf blade length, leaf blade width, midrib color, stooling capacity and stooling habit. Some of these plant characters which are influenced slightly by the environment are indicated in the text.

Using pseuostem height, base circumference and stooling capacity as basis, six groups of abaca cultivars and three groups of the species were proposed. These groupings were made to identify the varieties which are profuse stoolers and with all, large and vigorous pseudostems.

An outlines field procedure for classification was recommended to avoid collection of unnecessary data and to make the job of classification brief and easy.
