A model to predict the frequency of integration of fitness-related QTLs from cultivated to wild soybean
With the proliferation of genetically modified (GM) products and the almost exponential growth of land use for GM crops, there is a growing need to develop quantitative approaches to estimating the risk of esc...

Tracing the origins of stocks of the endangered species Primula sieboldii using nuclear microsatellites and chloroplast DNA
We examined the origins of cultivated stocks of the endangered species Primula sieboldii at the individual plant level by using an assignment test based on eight microsatellite loci and regional features of chlor...

Effect of population density of compatible neighbours on inbreeding level within a Primula sieboldii population
We investigated the effect of population density of compatible neighbours on inbreeding level of Primula sieboldii, a heterostylous clonal herb. Pollinator availability, seed set, selfing rate, diversity of polle...

Genetic Combining Ability of Petal Shape in Garden Pansy (Viola × wittrockiana Gams) based on Image Analysis
Flower appearance is an important target for improvement in garden pansy (Viola × wittrockiana Gams). Flowers of this species consist of three petal types: inferior, lateral, and superior. By means of principal-c...

Effect of floral morphology on pollination in Brassica rapa L
Flower structure, especially the anther–stigma separation (ASS), is well known to affect pollination efficiency, and thus to potentially increase or decrease seed production in crops. Therefore, investigating ...

Quantitative evaluation of the petal shape variation in Primula sieboldii caused by breeding process in the last 300 years
Primula sieboldii (E. Morren) has been a popular garden plant at least since the Edo period, about 300 years ago. We compared petal form between cultivars and wild populations in order to characterise the changes...

Quantitative evaluation of flower colour pattern by image analysis and principal component analysis of Primula sieboldii E. Morren
In Primula sieboldii E. Morren, many cultivars have been bred with the purpose of obtaining various petal colour patterns. Colour pattern is an important breeding target in this species, and the availability of a...

Map** QTLs influencing rice floral morphology using recombinant inbred lines derived from a cross between Oryza sativa L. and Oryza rufipogon Griff
To understand the genetic basis of floral traits associated with the mating system in rice, we analyzed pistil, stamen and glume traits using a recombinant inbred line population, derived from a cross between...

Hydroxyapatite Coating on Thermal Titanium Substrate in Aqueous Solution
A hydroxyapatite, HAP, film was deposited on a titanium substrate in an aqueous solution, at an ambient temperature and ambient pressure. The solution included 3 mmoldm-3 Ca(H2PO4)2 and 7 mmol dm-3 CaCl2 at pH 5....

Restriction fragments homologous to mitochondrial plasmid-like DNAs are located within limited chromosomal regions on the rice nuclear genome
The chromosomal locations of restriction fragments of nuclear DNA that were homologous to four mitochondrial plasmid-like DNAs, namely, B1, B2, B3 and B4, were analyzed by restriction fragment length polymorph...

Possibility of Expanding Genetic Variation by Limited Pollination Based on the Reproductive Success Rate (RSR) of Pollen Grains Deposited on Stigma
We have already proposed the new concept of “Reproductive Success Rate” (RSR) pertaining to the pollen grains deposited on a stigma and the ovules in a pollinated flower (Namai and Ohsawa 1986). The RSR of pol...

Variation of Reproductive Success Rates of Ovule and Pollen Deposited upon Stigmas According to the Different Number of Pollen on a Stigma in Angiosperm
In this Chapter,we would like to bring up a new concept, namely the “Reproductive Success Rate(s)” (abbreviated as RSR) of ovule and pollen deposited upon stigmas. The RSRs of ovule and pollen on stigmas mean ...
