Epistasis in the Inheritance of Quantitative Characters in Jute1
- A. M. Eunus and

Inheritance of plant height and earliness was studied in two crosses, ‘0-753’ ✕ ‘Desimasua’ and 0-753 ✕ ‘0-6E,’ of jute (Corchorus olltorius L.) using P1, P2, F1, F2, B1. and B2 progenies. Herltability was found to be 57% and 59% for earliness and 49% and 8% for plant height, respectively, in 0-753 ✕ 0-6E and 0-753 ✕ Desimasua. Over dominance and partial dominance were detected for plant height in 0-753 ✕ Desimasua and 0-753 ✕ 0-6E, respectively, whereas partial dominance was observed for earliness in both crosses. Expected genetic advance in F3 means over F2 means under selection suggested that transgressive segregation was expected for both the characters in segregating progenies. Detection and estimation of epistasis indicated that in the cross 0-753 ✕ Desimasua, epistasis was due to additive ✕ dominance effects for the two characters, whereas in 0-753 ✕ 0-6E, epistasis was due to all three types of non-allelic interaction for plant height.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
