Efficiency of Selection Methods of Rice

The experimental material consisted of three crosses viz; BG102/BPT5204, BG102/Naveen and BG102/Reshmi (Commercial Pvt. Hybrid Victory seeds) of rice (Oryza sativa L.), each of the crosses represented a separate experiment. These F2 selected plants were grown at rice experimental area, Birsa Agricultural University, Kanke, Ranchi, during kharif, 2014 in RBD with two replication and two methods of sowing such as direct seeded and transplanted at twenty days interval; each plot measuring 2.7 x 0.4 meter size. ANOVA revealed that mean sum of square due to progeny of crosses viz; Cross-I, Cross-II of F3 under different selection group followed by two dates of sowing for all most all traits were highly significant except for traits PH and GYP plot while in Cross-III, all characters were found highly significant except GPP in Ist date of TP under HY group indicating the presence of ample amount of genetic variability among progenies for all characters under study.
