INHERITANCE AND LINKAGE STUDIES IN SOYBEAN

Published on Nov 01, 2019 10:46 AM

Inheritance of nine morphological characters in six crosses of soybean revealed hypocotyl
colour (Hphp), petal colour (Wtwtl,leaflet shape (LIl2lrW, growth habit (Dttdttl, pubescent
pods (P2Pz) and pod shattering (Shtsht) each to be governed by a single gene whereall, seed
coat colour (GtG2gtg2) and defective seed coat (DetD~detdez)were under digenic control.
Pod colour (LtL2hh) gave monogenic and digenic segregation in different crosses. Out of
122 joint segregations, significant linkages was observed in 3S cases with the crossing over
values for different gene pairs in the range of 1.08-46.600/•. Based on the pool data ofstraight
and reciprocal crosses three gene maps are constructed. Linkage association for the
characters, viz., hypocotyl colour, leaflet shape, growth habit, pod shattering, etc. could not
be established.
