Plant regeneration via somatic embryogenesis in sugarcane
Plants, regenerated from callus cultures of sugarcane (Saccharum officinarum L.) clone IJ76-316, originated through somatic embryogenesis. Callus cultures were established from primordial leaves andExpand

Hybrids between tetraploid Italian and perennial ryegrass
SummaryHybridization frequency was investigated between tetraploid perennial and Italian ryegrass (Lolium perenne X multiflorum) without emasculation by using genetic markers. The Italian phenotypes,Expand

The Genus Collinsia. XIII. Cytogenetic Studies of Interspecific Hybrids Involving Species with Pediceled Flowers
1. Nineteen interspecific hybridizations were attempted between species of Collinsia Nutt. (Scrophulariaceae) included in the group with sessile flowers and in the groups with the anomalous species,Expand

Trisomics of ryegrass and their transmission
SummaryPrimary trisomics of perennial ryegrass, Lolium perenne L., were studied for meiotic behaviour, fertility, morphology and trisome transmission. Trisomics differed from each other in meanExpand

Chromosome behavior in a hypertriploid plant of ryegrass
SummaryA hypertriploid (2n = 22) was detected in the progeny of a desynaptic diploid (2n = 14) plant of perennial ryegrass,Lolium perenne L. The hypertriploid did not differ in morphology from itsExpand

Trisomics and aneuploids of ryegrass
SummaryPrimary trisomics (2 n + 1 = 15), double trisomics (2 n + 1 + 1 = 16) and aneuploids with 24 to 30 chromosomes, as well as a diploid and tetraploids, were found in the progeny of aExpand

Effect of temperature and barbiturates on a desynaptic mutant of ryegrass.
Abstract In microsporocytes of a diploid desynaptic mutant ds ds of ryegrass, high temperature markedly increased the degree of desynapsis while barbiturates decreased it. The mean bivalent numberExpand
