Development of new cytoplasmic source of male sterile lines in rice for shallow lowland

Two shallow lowland male sterile lines, MotiA and PadminiAwith Miz.4 cytoplasmic source were developed throughintervarietal hybridization and recurrent backcrossing withtheir respective parents. In all probability, MotiA and PadminiA of Miz.4 source may be genetically different from the Wild abortiv...

Description
Summary:Two shallow lowland male sterile lines, MotiA and PadminiAwith Miz.4 cytoplasmic source were developed throughintervarietal hybridization and recurrent backcrossing withtheir respective parents. In all probability, MotiA and PadminiA of Miz.4 source may be genetically different from the Wild abortive CMS source (V.20A). These two CMS lines are semitall in stature, photosensitive, of late duration in flowering with easy fertility restoration ability, and thus could be useful for developing hybrid rice suitable for shallow lowland areas.[PUBLICATION ABSTRACT]
