Description The present investigation entitled “Studies on growth, yield and quality of different cultivars of banana in Andhra Pradesh” was conducted at Horticulture Research Station, Kovvur, West Godavari during 2010-11. The objective of the experiment is to recommend a suitable cultivar with higher yield, quality and shelf life for commercial cultivation in coastal areas of Andhra Pradesh. In field experiment, eight banana cultivars viz., Dwarf Cavendish, Robusta, Grand Naine, Martman, Tella Chakkerakeli, KBS-01, Yangambi Km-5 and Karpura Chakkerakeli were evaluated for growth and yield potential. The data collected from this experiment was further utilized for the genetic analysis viz., PCV, GCV, Correlation studies and Path coefficient analysis.
Among the cultivars of banana evaluated, the maximum plant height and pseudostem girth was recorded in Martman at shooting stage, the higher number of suckers were observed in Dwarf Cavendish, whereas the total leaves production was highest in Martman followed by Grand Naine, similarly green leaves were higher in Martman followed by Dwarf Cavendish. Leaf area was significantly highest in Martman followed by Tella Chakkerakeli and Karpura Chakkerakeli. The early shooting was observed in Dwarf Cavendish whereas late shooting was recorded in Martman and also same trend was observed in days taken to harvest. The growth rate for plant height was maximum at early stage of crop growth in KBS-01. With regards to LAI, Martman recorded the highest value.
Regarding to yield attributes, the maximum bunch weight and yield was recorded in Grand Naine. The number of hands per bunch and fingers in 2nd hand were higher in Karpura Chakkerakeli and Yangambi Km-5 respectively, whereas finger length and finger girth were highest in Grand Naine. With respects to the quality, Tella Chakkerakeli recorded significantly higher to characters viz., TSS, total sugar content and reducing sugar content, but it had less shelf life. Comparatively the highest shelf life was recorded in Grand Naine.
In genetic studies, high Genotypic and Phenotypic coefficient of Variation, heritability and genetic advance as per cent mean were observed in leaf area, bunch weight and yield per plant. In correlation studies, significant positive association of yield per plant was observed with bunch weight, number of hands per bunch, fingers in 2nd hand and finger length at the genotypic and phenotypic level. Therefore improvement of these characters might be helpful in improving the yield in banana. With regards to Path coefficient analysis, the first ranking components of yield of banana were bunch weight, number of hands per bunch, fingers in 2nd hand as these characters directly influenced the bunch yield.
In banana, on basis of results obtained in the present investigation among eight cultivars of AAA and AAB genomic groups tested, Grand Naine recorded highest yield followed by Martman and Robusta. The variety, Grand Naine also recorded higher values for yield attributing characters such as bunch weight, number of hands per bunch and number of fingers in hand with longer shelf life. Therefore, above cultivar can be recommended for commercial cultivation in coastal areas of Andhra Pradesh
