    Notes: [Auszug] In the somatic complement of P. ramosum one pair of satellited chromosomes was seen and the centromeres in all the chromosomes were either median or sub-median (Fig. 1). At diakinesis and metaphase I of meiosis in microsporocytes, there were five bivalents (Fig. 2). One plant was heterozygous for ...

    Notes: [Auszug] Twenty-five awned mutants of N.P. 799 and six jsuch mutants of N.P. 809 were grown in replicated rod-row trials during 1958. All the awned mutants of N.P. 799 yielded more than the parent strain, while in N.P. 809 some yielded better and some lower. In both the varieties, the mutants found to be ...

    Magnitude of hybrid vigor retained in double haploid lines of some heterotic rice hybrids (1995)
    Springer
    Theoretical and applied genetics 90 (1995), S. 253-257 
    Details
    ISSN: 1432-2242
    Keywords: Oryza sativa L ; Rice ; Heterosis Anther culture ; Double haploid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Sixty one double haploid (DH) lines were evaluated for yield components and yield and compared with the three corresponding hybrids from which they were derived through anther culture. Analysis of a 6×6 diallel experiment led to the selection of these hybrids based on their high heterosis and revealed the nature of gene action of the characters under evaluation. The DH lines along with the hybrids and parents were planted following a simple lattice design with two replications. The results show that in DH lines the values of the characters expressing predominantly additive genetic effects could reach the heterotic level of the hybrids. For characters including yield showing predominantly dominance effects, values in the DH lines were significantly lower than those of the corresponding hybrids. The promising DH lines, however, possess a higher yield potential than the better parents.

At the onset of mitosis the nucleus is resolved into chromosomes, and configurations resembling the prophase and metaphase chromosomes of other organisms could be seen in squash preparations (Figs. 1 and 2). The exact chromosome number is, however, not clear. We have seen eight ...
