CMS A-lines (IR 58025 A) and KMR-3 as R- line were procured from the State Rice Research Station, Chin surah, Hooghly during December 2011. The seeds of A-line and R-line were sown in the seed bed at the research field of the Crop Research Farm (CRF) under The Department of Botany, The University of Burdwan on 18/12/2011 following anorms of CMS breeding technology. These seedlings were transplanted accordingly for raising F2 plant population. These F1 seeds were undertaken for F2 population which was observed critically during its growth and developmental phase till harvesting. These F1 seeds were sown in the seed bed maintaining three types of spacing. Five organic manure treatments viz. T0, T1, T2, T3, T4 were applied in the soil of each variety and spacing sub plot i.e total 30 sub plots were maintained following Randomized Block Design (RBD) in four replications. various metrical characters viz. No. of tillers, No. of total leaves, plant height, No. of tillers bearing inflorescence, total yield per bight were studied critically and recorded all the data carefully for further calculations, no disease occurrence was found in the field of F2 generations. The main aims and objectives of this experimentation were to study the yield attributes and disease free F2 seed from the hybrid F1 rice population evolved through CMS breeding technology.
