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

Published on

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.
