Abstract
Segregating patterns for pollen fertility of five crosses were studied involving two CGMS lines and four restorers viz., ICPA 2043/ICP 6399, ICPA 2043/ICP 9149, ICPA 2043/ICPR 4105, ICPA 2092/ICPR 4105 and ICPA 2092/KA 91-25 in F2 and BC1F1 generations. The crosses exhibited 13: 3 and 3:1 ratios, respectively in F2 and BC1F1 indicating the involvement of two dominant genes with one basic and one inhibitory gene action for fertility restoration. However, three crosses, ICPA 2092/ICP 6399, ICPA 2092/ICP 9149 and ICPA 2043/KA 91-25 recorded the ratio of 9 : 3 : 4, 12 : 3 : 1 and 9 : 7 and 1 : 1 : 2, 2 : 1 : 1 and1 : 3 in F2 and BC1F1 populations, respectively and these are confirming that supplementary, masking and complimentary gene actions.
