To understand the mode of flesh color inheritance in loquats (Eriobotrya japonica), segregation of flesh color (yellowish orange vs. whitish yellow) was investigated in 1,643 F_1 progenies derived from 32 breeding populations. All F_1 progenies ob...
A simple tensiometer is a device for measuring the degree of dryness of soil above pF 2.8, thereby lowering the water level within it. We studied the method to estimate water stress in citrus trees using the simple tensiometer. The results showed ...

The genetic variation of loquat (Eriobotrya japonica (Thunb.) Lindl.) was characterized by SSR markers developed from apple and pear, using 94 loquat accessions in Japan. Fourteen of the 24 SSR markers derived from apple could successfully ...

To obtain genetic information on carotenoid content in Citrus fruit for a breeding program, we investigated quantitative trait loci (QTL) in a mapping population derived from a cross between 'Okitsu-46' and 'Nou-5'. Among individual progeny...

Assessment of the tree vigor of grafted rootstocks in citrus requires intense labor, a long period, and large fields because tree vigor is judged through cultivation tests with adult trees. We have developed a method to predict tree vigor at an ea...

A RAPD marker, linked to the resistance gene Pse a to loquat canker disease (caused by Pseudomonas syringae pv. eriobotryae), was screened from 2390 primers or primer combinations by using bulked DNA samples derived from progenies of 'Yougyoku'×74...

Polyembryony, which is a specific true-seed propagation system generated by somatic embryogenesis in nucellar tissue, occurs widely in the genus Citrus. To refine the genetic map of the polyembryony locus in Citrus, we obtained DNA m...

Fluorochrome staining with chromomycin A3 (CMA) was used to characterize and compare the CMA banding patterns of chromosomes in 14 accessions of 12 species of major Citrus species. All accessions had 2n = 18 chromosomes. These ch...

Some authors seem to have confused and incorrectly described the mandarin cultivars Kabuchi and Keraji. Both cultivars originated on the Amami Archipelago and have been cultivated on Kikaijima island located in Kagoshima Prefecture. Fruit of Keraj...

One of the male sterile traits in citrus is the interruption of anther development. It has been known that hybrids with undeveloped anthers segregate among hybrids with satsuma mandarin. In this study, the mode of inheritance of undeveloped anther...
