| 0 | PI 643128 | Early Plant Death | Oryza sativa L. | Arkansas, United States | GSOR | | | 2006 | DEVELOPED | 05/2006 | | | | | Genetic material | The early plant death mutant (GSOR 21) was observed in 5 out of 12 plants in a single M2 row in 2003. In subsequent tests, plant death began soon after emergence and concluded ca. 80 days after planting. In a sample of 100 or more grains, brown rice length, width and weight, from the surviving plants were 6.5 mm, 2.3 mm, and 20 mg, compared to 6.8 mm, 2.4 mm, and 22 mg for the parent genotype. In 2005 seeds from heterozygous normal M4 plants were composited to provide a genetic stock which will segregate 3 normal:1 mutant. Specialized propagation procedures: To maintain the population that segregates 3 normal:1 mutant, grow a segregating population from the above seed source, and harvest the normal (living) plants. The progenies of these plants will again segregate 3 normal:1 mutant and seeds of the segregating progeny parent plants may be bulked to replenish the seed stock | 1706685 | PI 643128 |
| 1 | PI 643129 | Narrow Leaf | Oryza sativa L. | Arkansas, United States | GSOR | | | 2006 | DEVELOPED | 05/2006 | | | | | Genetic material | The narrow leaf mutant (GSOR 22) was observed in 2 out of 9 plants in a single M2 row. In subsequent tests, flag leaf dimensions of the narrow leaf mutant were 14.88 cm long, and 0.56 cm wide, compared to 14.59 cm and 0.99 cm for the parent. In a sample of 100 or more grains, brown rice length, width and weight of the mutant plants were 6.2 mm, 2.3 mm, and 18 mg, compared to 6.8 mm, 2.4 mm, and 22 mg for the parent genotype. Seeds of plants were composited to form a genetic stock that is pure breeding for the narrow leaf mutant phenotype. | 1706690 | PI 643129 |
| 2 | PI 643130 | Extreme Dwarf | Oryza sativa L. | Arkansas, United States | GSOR | | | 2006 | DEVELOPED | 05/2006 | | | | | Genetic material | The extreme dwarf mutant (GSOR 23) was observed in 5 out of 11 plants in a single M2 row in 2003. In subsequent tests, the extreme dwarf plants averaged 24 cm tall compared to 80 cm for the homozygous tall sibs. In a sample of 100 or more grains, brown rice length, width and kernel weight from the mutant plants were 6 mm, 2.1 mm, and 16 mg, compared to 6.8 mm, 2.4 mm, and 22 mg for the parent genotype. Seeds of extreme dwarf plants were composited to form a genetic stock that is pure breeding for the extreme dwarf mutant phenotype. | 1706694 | PI 643130 |
| 3 | PI 643131 | Gold Leaf | Oryza sativa L. | Arkansas, United States | GSOR | | | 2006 | DEVELOPED | 05/2006 | | | | | Genetic material | The gold leaf mutant (GSOR 24) was observed in 2 out of 7 plants in a single M2 row in 2003. In subsequent tests, the gold, or bright yellow, leaf color appeared ca. 78 days after planting and remained in the leaf material through harvest. In a sample of 100 or more grains, brown rice length, width and kernel weight from the mutant plants were 6.7 mm, 2.4 mm, and 21 mg, compared to 6.8 mm, 2.4 mm, and 22 mg for the parent genotype. Seeds of the gold leaf plants were composited to form a genetic stock that is pure breeding for the gold leaf mutant phenotype. | 1706698 | PI 643131 |
