Characterization of Rice (Oryza Sativa L.) Germplasm Through Various Agro-Morphological Traits
Journal Title: Scientia Agriculturae - Year 2015, Vol 9, Issue 2
Abstract
The present study was conducted to characterize the indigenous rice germplasm on the basis of morphological characteristics at Khyber Pakhtunkhwa Agricultural University Peshawar. The germplasm consisted of 30 rice accessions were planted in randomized complete block design (RCBD). The data were recorded on 32 different agro-morphological traits (15 qualitative and 17 quantitative). The rice germplasm exhibited sufficient genetic variation for most of the qualitative and quantitative traits. Variation was observed for all the qualitative traits except anther color and ligule shape. Highly significant differences (p<0.01) were observed for the traits of flag leaf length, flag leaf breadth, culm length, days to 50% flowering, panicle length, length of primary branches panicle-1, secondary branches panicle-1, grain length, grain width, awn length and percent leaf lession while significant differences (p<0.05) were observed for peduncle length and primary branches panicle-1. Rice accession 6531 took minimum days (95) in reaching to 50% flowering while accession 6512 displayed maximum panicle length (35.37 cm). Rice accession 6508 showed the highest values for flag leaf length (59.95 cm), primary branches panicle-1 (13), secondary branches panicle-1 (51), spikelets panicle-1 (240), and grain width (3.06 mm). The genetic potential of accessions 6508, 6547, 6512 and 6531 on account of excellent performance for various traits can be used in future rice breeding programs.
