Evaluation and Morphological Diversity Study of Plantain (Musa paradisiaca L.) Genotypes at Jamalpur Region of Bangladesh

Abstract

A study to evaluate the performance of yield and yield contributing characters and morphological diversity of plantain genotypes, was conducted at the fruit farm and fruit characteristics were studied in the laboratory of the Horticulture Research Centre, Regional Agricultural Research Station (RARS), Bangladesh Agricultural Research Institute (BARI), Jamalpur, Bangladesh during March 2013 to April 2014. Sixteen plantain genotypes viz. BARI Kola-2, ITC-1418, Local-1, Local-2, MP-1, MP-15, MP-18, MP-2, MP-24, MP-25, MP-3, MP-6, MP-7, MP-8, MP-ISD-02, and MPR-001, were included in the study. Plantain genotypes displayed significant variation related to plant height, base girth, number of leaves, days to panicle appearance, days to first flowering, days to last flowering, days to harvest, bunch weight, bunch length, bunch breadth, peduncle weight, number of hands per bunch, individual hand weight, weight of total hands, number of fingers per hand, finger length, finger diameter, individual finger weight, and fruit yield. MP-24 produced the tallest plant (3.47 m) and the genotype ITC-1418 had the shortest plant (2.47 m). The genotype MP-8 exhibited the highest base girth (70.41 cm) as against the lowest base girth in BARI Kola-2 (46.01 cm). The genotype MP-8 demonstrated the maximum number of leaves (8.48) as compared to the minimum number of leaves in MP-3 (4.81). Early harvest was gained from the Local-2 genotype (354.50 days) and delayed harvest in MP-18 genotype (401.00 days). MP-3 produced the heaviest bunch (16.08 kg) as compared to the lightest bunch in BARI Kola-2 (8.29 kg). The highest number of hands per bunch was recorded in MP-3 (8.91) whereas the least number of hands was recorded in MPR-001 (4.81). MP-3 resulted in the maximum number of fingers (110.08) as compared with the smallest number of fingers in MPR-001 (44.81). The genotype Local-1 produced the highest length (19.48 cm) and diameter (4.68 cm) of finger, while these were the lowest in the genotype MP-8 (13.81 cm and 3.69 cm). The genotype MPR-001 produced the biggest finger (190.25 g) while MP-8 had the smallest finger (127.08 g). The highest (40.08 t/ha) fruit yield was obtained from MP-3 which was statistically at par to the MP-2 genotype (35.33 t/ha) and the lowest from BARI Kola-2 (19.46 t/ha). Principal component analysis of plantain genotypes was performed for the identification of characters with better capability for selection genotypes. Cluster analysis of plantain genotypes was also completed to arrange the genotypes into five homogeneous groups and it confirmed the clustering pattern of principal component analysis. The Pearson correlation also determined among the characters studied of plantain genotypes. The yield of the plantain genotypes demonstrated strong positive and significant correlation with bunch weight, bunch length, bunch breadth, peduncle weight, number of hands per bunch, weight of individual hand, weight of total hands, and number of fingers per bunch. The results directed that improvement of these characters can contribute to increasing in the yield of the crop.
