Abstract

Abstract: Agronomic characters and fiber quality were assessed from 60 developed abaca hybrids (BC3F1) and two parents (Pacol and Laylay). Selection of abaca hybrids possessing the best agronomic characters and fiber quality was made through selection indices. Differences on the agronomic characters such as number of stools, number of leaves, plant height, girth, pseudostem fresh weight and leaf sheath numbers on all the hybrids as compared to its parental (Pacol and Laylay) were seen in the t-test analysis done. In terms of the fiber quality, some of the hybrids have higher fiber length, fiber weight, percent fiber recovery and tensile strength compared to its parental. Fiber length ranges from 13.8 to 304.4 cm, fiber weight from 0.0025 to 0.0682 kg, percent fiber recovery from 0.2891 to 1.6713 % and tensile strength ranges from 14.24 to 38.75 kg/g*m. In terms of the fiber quality such as fiber length, fiber weight and percent fiber recovery of every leaf sheath position, there is no difference between the inner and middle portion however, the outer leaf sheath is resulted in shorter fiber length, lighter fiber weight and lesser fiber recovery and in contrast differences were observed in the tensile strength of the fiber derived by every leaf sheath position.Four hybrids were selected with good agronomic characters especially high tensile strength (29.01 kg g-1m-1 to 32.72 kg g-1m-1) and good fiber recovery (0.51 % to 0.80%).
