Pearl millet protein is deficient in several essential amino acids but averages 35% higher lysine levels than sorghum (Rooney Development of a Set of Chromosome Their easy crossability with pearl millet, coupled with regular chromosome pairing in the resulting hybrids, should facilitate gene introgressions. However, in hybrids with the Triticeae species, chromosome elimination occurred during embryogenesis. Chromosome no. they were merged into a single species with pearl millet (Brunken et al. Crossability of bread wheat with pearl millet was relatively high. The mitotic behavior of pearl millet chromosomes was analyzed to determine whether micronuclei are formed exclusively by nonsegregating chromosomes as is usually assumed (Ford and Correll, 1992). Meiotic analysis confirmed the involvement of 2 non-homologous chromosomes in the exchange of segments in all interchange stocks. All pearl millet chromosomes were eliminated in a random sequence between 6 and 23 d after pollination. Genotypes of elephant grass, millet, and triploid and hexaploid induced hybrids were compared. In pearl millet (Pennisetum americanum (L.) Leeke, 2n = 14), a wide range of intraplant chromosome numerical variation occurring in pollen mother cells at meiosis within the same anther, floret, or spike was found in eight plants.The types of mosaicism encountered were haploid–diploid, diploid–tetraploid, haploid–diploid–aneuploid, and diploid–tetraploid–aneuploid–teloaneuploid. Pearl millet’s large chromosomes — larger than in most other species in the tribe Paniceae — and a distinctive pair of nucleolar organizers make it possible to study interge- nomic and intragenomic chromosome pairing in interspecific hybrids (Jauhar 1968). OSTI.GOV Journal Article: Cytogenetics and reproductive behavior of 48-chromosome pearl millet x Pennisetum squamulatum derivatives The expected F 1 chromosome complement was also found in a primary endosperm mitosis. As in the case of maize crosses, low crossabilities of durum wheat and hexaploid triticale with pearl millet can be attributed to the absence of D‐genome chromosomes. Cenchrus americanus (L.) Morrone] is an important dryland cereal crop in the arid and semi‐arid regions of the world. Distribution. X refers to haploid chromosome number. 15. Pearl millet is a diploid with seven fairly large chromosomes and a large number of genes that are already known and definitively mapped. Backcrosses to diploid pearl millet (2n = 14) resulted in 12 28- or 27-chromosome male and female-sterile plants from more than 600 pollinated inflorescences. Br., syn. Pearl millet grain generally has a crude protein level (10.3%) that is higher by 1 to 2% than sorghum [Sorghum bicolor (L.) Moench] grown with similar cultural practices.
