This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as

| 0 | PI 698102 | SC14_072 | Oryza sativa L. | Arkansas, United States | NLGRP | | Not Available | 2021 | DEVELOPED | | | | | | Breeding material | SC14_072, selected for kernel length (7.91 mm), is classified as an extra-long grain and captures much of the kernel length of Estrela (8.24 mm) with low amylose content and high gelatinization temperature based on genetic marker alleles The plant is pubescent, average days to 50% heading is 74 d, plant height is 119 cm, and it has the Pi-z and Pi-ks genes for resistance to rice blast disease (Magnaporthea oryzae). SC14_072 has the same SNP alleles for grain length as Estrela near the candidate genes LONG KERNEL 3 (GRAIN SIZE 3) [LK3 (GS3)] and GRAIN LENGTH 3.2 (GL3.2) on chromosome 3, GRAIN LENGTH 7 (GL7) on chromosome 7 and GRAIN WIDTH 8 (GW8) on chromosome 8. The fact that SC14_072 has a shorter grain than Estrela may be attributed to the same SNP alleles for grain width as NSFTV199 near candidate genes SMALL AND ROUND SEED 3 (SRS3) and GRAIN WIDTH 5 (GW5) on chromosome 5. Its grain length:width ratio is 3.00 and it has 4.64 percent grain chalkiness. | 2113353 | PI 698102 |
| 1 | PI 698103 | SC14:166 | Oryza sativa L. | Arkansas, United States | NSGC |  | | 2021 | DEVELOPED | | | | | | Breeding material | SC14_166, selected for increased panicle branching, number of seed per panicle and panicle weight, is a medium grain with low amylose content and high gelatinization temperature based on genetic marker alleles. The plant is glabrous, average days to 50% heading is 70 d, plant height is 126 cm, and it has the Pi-ks gene for resistance to rice blast disease (Magnaporthea oryzae). The panicles have a mean of 12.6 primary branches per panicle, more than either of the parents, and the number of seeds per panicle (115.6) is similar to NSFTV199 (121.5). SC14_166 has the same SNP alleles as the NSFTV199 parent for increased spikelet number, near the SPIKELET NUMBER (SPIKE) gene on chromosome 4, and for panicle branching, near the FRIZZY PANICLE (FZP) gene on chromosome 7. On chromosome 1, it has the NSFTV199 allele near the grain number 1A (GN1A) gene. The SC14_166 kernel length (6.86 mm) was significantly shorter than Estrela (8.24 mm) but longer than NSFTV199 (5.63 mm) and it possesses the Estrela alleles for grain length on chromosome 3 and width on chromosome 8. Its grain length:width ratio is 2.63 and it has 4.52 percent grain chalkiness. | 2113354 | PI 698103 |
