Intraclonal variations and nutritional studies in banana cv. Palayankodan

Abstract

The investigations were carried out at the Banana Research Station, Kannara, during 1981-84 in the banana cv. 'Palayankodan'. Twenty four accessions were subjected to detailed analysis with respect to growth, yield and quality. The plants of the accessions differed significantly with regard to height and girth of pseudostem during the later stages of growth , both in the plant crop and in ratoon 1. Significant differences observed in the number of functional leaves were not consistent. Area of the third leaf at shooting varied significantly in all the three crops. The trend in variation between the crops, however, was not consistent. Interval of leaf production, total number of leaves produced and the density of stomata in the upper surface of the leaf lamina showed significant differences. The duration from planting to shooting in ratoon 1 alone varied significantly. The plant crop took more time than ratoon 1 and ratoon 2 to come to harvest. The content of nutrient elements in the index leaf did not exhibit significant variations. The reactionof the accessions to the important pest (rhizome weevil) and diseases (bunchytop and Sigatoke) varied considerably.
