Abstract

Studies on tossa jute (Corehorus olitorius L.) were taken up to ascertain the genetic architecture of fibre yield, its components and quality parameters from 11 x 11 diallel analysis. The combining ability analysis revealed that both additive and non-additive gene action were involved in the inheritance of all the characters. However, preponderance role of additive variances was marked for basal diameter and rest of the characters were governed by mainly non-additive variance excepting fibre percentage where both the variances were effective. Among the parents JRO-524 and KEN/DS/060C exhibited significant gca effects for fibre yield, plant height, node number, green weight, stick weight, fibre percentage and fibre fineness. TAN/SM/040C and TAN/NY/013C showed lowest peroxidase activity. Eight hybrid combinations exhibited high mean and significant sea effect for fibre yield and most of the yield component characters and five hybrid combinations showed significant lower peroxidase activity. Most of the sea effects involved parents with high x high or high x low gea effects. KEN/SM/024C x JRO-3670, JRO-524 x NPUYPT/026C, KENIDS/060C x TANIX/112C crosses are produced better quality fibre for textile purpose.
