Genetic Analysis of fibre anatomy characters in Tossa Jute

This book is about Prediction of fiber yield and its quality by rapid method for screening in Tossa jute (Corchorus olitorius L.) and its usefulness of fiber anatomy characters for predicting fiber yield and quality comparison to morphological characters. Prediction of fiber yield and quality are essential in jute breeding program. Plant height and basal diameter are moderately reliable indicators of fiber yield in jute, but these characters are not useful to judge fiber quality owing to the large variability of fiber contents and fiber bundle structure, which is again dependent on retting condition. Fiber anatomical characters are useful indicators for judging fiber yield and quality, but are rarely used in breeding programs. Results indicate that fiber anatomical characters are highly suitable for predicting fiber yield and quality. The present investigation entitle was undertaken to understand the nature of gene action, combining ability effects of parents, magnitude of exploitable Heterosis and components of genetic variance for nine different anatomical characters.
