Assessment of genetic diversity in accessions of pearl millet (Pennisetum glaucum) and napier grass (Pennisetum purpureum) using microsatellite (ISSR) markers
Pearl millet (Pennisetum glaucum (L.) R. Br.) and napier grass (Pennisetum purpureum Schumach) are the most economically important species in the genus Pennisetum. Knowledge of genetic diversity of these two species would enhance their potentials for utilization. The present work assessed the genetic diversity and phylogenetic relationship among Nigerian and Indian accessions of pearl millet an...
متن کاملGenomic homeology between Pennisetum purpureum and Pennisetum glaucum (Poaceae)
The genus Pennisetum (Richard, 1805) includes two economically important tropical forage plants: Pennisetum purpureum (Schumacher, 1827) (elephant grass), with 2n = 4x = 28 chromosomes and genomes A'A'BB, and Pennisetum glaucum (Linnaeus, 1753) (pearl millet), with 2n = 2x = 14 chromosomes and genomes AA. The genetic proximity between them allows hybrids to be obtained (2n = 3x = 21) that yield...
متن کاملDNA elimination in embryogenic development of Pennisetum glaucum x Pennisetum purpureum (Poaceae) hybrids.
Interspecific hybridization between Napier grass (Pennisetum purpureum), which is widely grown in Brazil for cattle forage, and pearl millet (Pennisetum glaucum) has been used as a breeding strategy for the development of improved cultivars. However, the hybrid between these two species is sterile due to its triploid condition (2n = 3x = 21 chromosomes), which hinders its use in crop breeding p...
متن کاملNucleotide polymorphism in the Adh1 locus of pearl millet (Pennisetum glaucum) (Poaceae).
We investigated nucleotide polymorphism in the Adh1 locus of pearl millet (Pennisetum glaucum) (Poaceae) by determining the DNA sequence of 20 alleles from 10 individuals. The individuals were sampled from throughout pearl millet's indigenous range and represent both wild and cultivated accessions. Our results indicated that there is little nucleotide polymorphism in the Adh1 locus. Estimates o...
متن کاملAgronomic and physiological responses of pearl millet ecotype (Pennisetum glaucum (L.) R. Br.) to saline irrigation
The objective of this study was to identify morphological and physiological traits for salinity tolerance in Tunisian autochthonous ZZ pearl millet ecotype (Pennisetum glaucum (L.) R. Br) under local conditions. ZZ ecotype was cultivated under different levels of salinity and growth parameters, water relations and mineral content were measured. Results showed that ZZ pearl millet ecotype was un...
