| Abstract/Description: | A study was carried out using 18 Spanish bunch groundnut genotypes to identify fresh seed dormant genotypes. Analysis of variance revealed that significant genotypic differences and genotype × year interaction for germination per cent at different weekly intervals. Two year study results showed that six advanced breeding lines viz., PBS 12171, PBS 12187, PBS 12189, PBS 12190, PBS 12191 and PBS 12192 identified for >35days duration of fresh seed dormancy, highest intensity and degree of fresh seed dormancy. Two advanced breeding lines PBS12193 and PBS 12196 identified for 28 days duration of fresh seed dormancy along with highest intensity and degree of fresh seed dormancy. However, an advanced breeding line PBS 12195 identified for 21 days duration of fresh seed dormancy along with average highest intensity and degree of fresh seed dormancy while one genotype ICGV 86031 also had 21 days duration of fresh seed dormancy along with average high intensity (94.4%) and degree of fresh seed dormancy (7.5). One advanced breeding lines PBS 12197 identified for 14 days duration of fresh seed dormancy along with high intensity (97.8%) and degree of fresh seed dormancy (7.5) during 2014 and 2015. Therefore, these genotypes were identified as new sources of fresh seed dormancy with different duration, high intensity and high degree of fresh seed dormancy. These genotypes could be used as donor parent in breeding programmes to develop high yielding Spanish bunch varieties with 2-5 week fresh seed dormancy in groundnut. |
