Abstract: A field trial was conducted for two years 2015-2016, at Rice Research Station Bahawalnagar to screen out the potential of new high yielding paddy strains. 8 candidate strains were tested, first grown in nurseries then transplanted in a plot size of 4.5 x8.25 ft. in last week of June. Recommended dose of N, P, K, Zn was applied. Lay out of the experiment was RCBD with three repeats. Physical parameters such as Days to 50 % flowering, Final plant height (cm). No of tillers per plant, Panicle length (cm), No of grains per panicle,1000 grain weight (gm.) and yield data in kgs per plot were recorded. It was revealed from the recorded data recorded that the strain PK- 8649 gave maximum yield 5797Kgs per hectare, 143 no of grains per panicles; 23.23gm thousands grain wt and 18 no of tillers per plant which is more than the already approved variety PS-2. Based on these observations, this can easily be concluded that the strain PK-8649 may be considered as advance line of high yield potential under Bahawalnagar conditions. Moreover after rice harvesting soil analysis report shows considerable improvement in soil pH, Ec and organic matter.
