| Abstract | The investigation was conducted at the Department of Crop Science Production and Research area of the Central Luzon State University-College of Agriculture, Science City of Mu?oz, Nueva Ecija, Philippines from January to May 2017. The experiment used Augmented Design with 5 blocks and 50 mutant lines with 3 checked varieties. M3 generation of 50 mutant lines of rice derived from the traditional variety of Pinilisa was evaluated for morphologically characterized mutant lines of Pinilisa. The traits observed similar to the wild type were intermediate blade pubescence, light green blade color, green basal leaf sheath color, erect blade angle, whitish ligule color, for 2-cleft ligule shape, and green culm color. While the traits observed differently among mutant lines were awnless and light green awn color, erect and semi-erect flag leaf angle, partly exserted panicle, just exserted, moderately well-exserted and well-exserted panicle, and awnless and whole length awning were based on 19 morphological traits. Cluster analysis using morphological traits revealed a relationship by forming one big cluster among the mutant lines. The wild type was attacked by stem borers which led to dead hearts; no data for growth and yield parameters were recorded. M3 generation of mutant lines recorded top three mutant lines in terms of days to 50% flowering and days to maturity, Crop Science Mutant Plant (CSMP) 204a, CSMP 204b and CSMP 203b, 3 short stature, CSMP 204a, CSMP 174 and CSMP 203b, 1 percent filled spikelet/panicle and number of filled spikelet/panicle, CSMP 92a, 6 good tillering ability, CSMP 17, CSMP 121, CSMP 91, CSMP 39, CSMP 203b and CSMP 6, 1 fine heavy grain weight, CSMP 202, 1 high yielding ability, CSMP 81, 1 longest grain length, CSMP 139 and 1 longest grain width, CSMP 114. The highest computed yield of 2.70 t/ha was from CSMP 81 while CSMP 204a, CSMP 204b and CSMP 114 were the early maturing (112 DAS) mutant lines. |
