Genomic 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 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...
متن کاملEfficient regeneration of pearl millet (Pennisetum glaucum (L.) R. Br.) from shoot tip cultures.
A simple, genotype-independent and efficient method for plant regeneration using shoot tip explants of pearl millet (Pennisetum glaucum) was established. Linsmaier and Skoog (LS) medium supplemented with 2,4-dichloro-phenoxyacetic acid (2.5 mg l(-1)) and kinetin (0. 2 mg l(-1)) was used for induction of embryogenic calli. Development of numerous somatic embryos was observed within 10 days after...
