INDUCED CHANGES IN THE GENETIC ARCHITECTURE OF SOME MACROMUTANTS OF JUTE (CORCHORUS OLITORIUS L.)

Abstract

From a nine-parent dialle! cross the nature of induced changes in the genetic architecture of five established macromutants were studied in olitorius jute for fibre yield, days to flower and average leaf area. The combining ability analysis revealed that each of the five mutants, although originated from the same mother cultivar, JR0-632, had different induced genetic background. Since these induced changes were not unidirectional, it may be concluded that these induced macromutants can provide a wide array of new genetic variability for breeding in a self- pollinated crop like jute.
