    Notes: Abstract Nine cytoplasmic male-sterile lines and five restorer lines were used in an incomplete diallel cross to analyze seed effects, cytoplasmic effects, and maternal gene effects on nutrient quality traits of indica rice (Oryza sauva L.). The results indicated that nutrient quality traits were controlled by cytoplasmic and maternal effects as well as by seed direct effects. Maternal effects for lysine content (LC), lysine index (LI), and the ratio of lysine content to protein content (RLP) were more important than seed direct effects, while protein content (PC) and protein index (PI) were mainly affected by seed direct effects. Cytoplasmic effects accounted for 2.41–20.80% of the total genetic variation and were significant for all nutrient quality traits. Additive genetic effects were much more important than dominance effects for all of the traits studied, so that selection could be applied for these traits in early generations.

    Microsatellites in Malus X domestica (apple): abundance, polymorphism and cultivar identification (1997)
    Springer
    Theoretical and applied genetics 94 (1997), S. 249-254

    Notes: Abstract Screening of an apple genomic library with (GA)15 and (GT)15 probes demonstrated that these repeats are abundant, occurring about every 120 and 190 kb, respectively. Microsatellites isolated from a small insert library enriched for (GA) repeats contained numbers of repeats ranging from 7 to 39. Primers to these microsatellite loci were able to direct the amplification of the repeats in 21 different cultivars. The majority of markers were highly polymorphic, diploid, and showed simple Mendelian inheritance, although about 25% of markers generated complex banding patterns consistent with the amplification of more than one locus. As few as three microsatellite markers were sufficient to differentiate between all 21 cultivars.

    Quantitative trait loci analysis for the developmental behavior of tiller number in rice (Oryza sativa L.) (1998)

    Notes: Abstract  A doubled-haploid rice population of 123 lines from Azucena/IR64 was used for analyzing the developmental behavior of tiller number by conditional and unconditional QTL mapping methods. It was indicated that the number of QTLs significantly affecting tiller number was different at different measuring stages. Many QTLs controlling tiller growth identified at the early stages were undetectable at the final stage. Only one QTL could be detected across the whole growth period. By conditional QTL mapping, more QTLs for tiller number could be detected than that by unconditional mapping. The temporal patterns of gene expression for tiller number could be different at different stages. Even an individual gene or genes at the same genomic region might have opposite genetic effects at various growth stages.
