Evaluation of Different Rice Genotypes for Various Quantitative and Yield Traits (Oryza sativa L.)

Rice is an important cereal crop grown in Pakistan and around the world. The present experiment was carried out in a Randomized Block Design with three Replications. Seven rice genotypes were grown to estimate correlation. Seven genotypes were studied viz. Niab 2K16, Sarshar, NIA Mehran, Shandar, Shahdab, Khushboo-95 and Shua-92.The analysis of variance of different characters was evaluated in rice genotypes which revealed high significance at P≤0.01 probability level for eight traits viz. plant height (cm), panicle length (cm), number of productive tillers plant-1, spikelets panicle-1, biological yield plant-1 (g), harvest index (%), grain yield plant-1(g),1000-grains weight (g). The mean performance results showed that plant height was maximum in Shandar and Khushboo, more tillers plant-1 were found in the genotypes Shandar and NIA-Mehran. The longest panicle was found in Khushboo,Niab and Shua , respectively. More number of grains panicle-1was observed in Sarshar and Shahdab respectively. More 1000-grain weight (g) was observed in Shua and Sarshar. Grain yield plant-1 (g) was observed greater in Nia mehranand Shandar, respectively. The biological yield was observed in Shandar, Shahdab and Shua-92.Harvest index was observed in Niab92 Sarhsar and khushboo. Grain yield plant-1 depicted a significant relationship with number of grains panicle-1 and thousand-grain weight (g) (r= 0.677**, 0.427**, 0.535**). Hence, it is suggested that Shandar, Khushboo, , Shua-92 can be used for future breeding program.
