Evaluation of Different Chaba (Piper chaba) Germplasm for Growth and Yield Performances

Abstract

Genetic diversity is the base for survival of plants in nature and for crop improvement. Diversity in plant genetic resources provides opportunity for plant breeders to develop new and improved cultivars with desirable characteristics. Therefore, an experiment was employed to determine the genetic variability and evaluate the growth performing parameters of different Chaba germplasm at the research field of Regional Spices Research Centre, Bangladesh Agricultural Research Institute, Magura during kharif 1 season in 2018-19 following completely randomized design with three replications. Six germplasm namely PCmag-001, PCmag-002, PCmag-003, PCmag-004, PCmag005 and PCmag-006 were collected from khulna region of Bangladesh and transplanted adjunct to Original Research Article Islam et al.; APRJ, 7(2): 23-29, 2021; Article no.APRJ.65016 24 different tree species mainly mango. Among the six germplasm heighest plant height (450 cm), number of branch (35), number of leaves (350), internodes length (16 cm) and vine diameter (2.5 cm) after one year of planting was recorded from PCmag-001 germplasm followed by PCmag-002 while the lowest plant height (450 cm), number of branch (35), number of leaves (350), internodes length (16 cm) and vine diameter (2.5 cm) were found from the germplasm PCmag-005. Through the observation of one year field trail in terms of growing characteristics the germplasm PCmag-001 and PCmag-002 can be chosen for future breeding material to release a commercial variety in southern part of Bangladesh.
