Mapping of qChalk1 controlling grain chalkiness in japonica rice
Molecular Biology Reports, 2023Rice grain chalkiness is an undesirable characteristic that affects grain quality. The aim of this study was to map QTLs controlling grain chalkiness in japonica rice.In this study, two japonica rice cultivars with similar grain shapes but different grain chalkiness rates were crossed and the F2 and BC1F2 populations were subjected to QTL-seq analysis ...

Anther Culture and Chromosome Doubling in Mediterranean Japonica Rice
2021Anther culture is the most used technique to produce doubled haploid lines in rice. This technique is well developed in a wide range of indica rice genotypes. However, in japonica type, and more specifically, the Mediterranean japonica, the protocols are yet to be optimized.

Indica-japonica differentiation in Chinese rice landraces
Euphytica, 1993Ninety Chinese rice landraces were examined with special reference to the indica-japonica differentiation in terms of traditional criteria, isozyme analysis and PCR analysis of the chloroplast DNA (cpDNA). Cultivars were separated into indica and japonica defined by a discriminant function (Z) based on key characters, as well as by isozyme genotypes ...

Utilization of weedy rice for development of japonica hybrid rice (Oryza sativa L.)
Plant Science, 2011Two representative weedy rice lines, three typical japonica varieties and three typical indica varieties were used for 6 pairs of reciprocal crosses. The morphological traits of twelve F(1) hybrid lines, their parents and four elite cultivars were investigated for heterosis over mid-parent (HM), over parent (HP) and competitive heterosis (CH) analysis.

Comparative Composition of Brown Rice Lipids (Lipid Fractions) of Indica and Japonica Rices
Bioscience, Biotechnology, and Biochemistry, 1999The brown rice lipids were analyzed from three japonica and two indica rices. They had substantially no difference in the ratio of NL, GL, and PL, the C16/C18 (16:0/the sum of 18:0, 18:1, 18:2, and 18:3) ratio in PL classes, and in the order of unsaturated index in each glycerolipid class among the five varieties.

Classifying Japonica Rice Cultivars with RAPD Markers
Crop Science, 1995Two major subspecies of rice (Oryza sativa L.), indica and japonica, are widely recognized. Japonica rice, which includes temperate and upland (tropical) cultivars, has been less well characterized by DNA markers than indica rice. The present study was undertaken to quantify genetic diversity with random amplified polymorphic DNA (RAPD) markers in a ...

Analysis of Vietnamese rice germplasm provides an insight into Japonica rice differentiation
Plant Breeding, 2003AbstractGenetic differentiation among landraces of rice in northern Vietnam that lie in the centre of genetic diversity of Asian cultivated rice was analysed using DNA markers, and morphological and physiological traits to obtain an insight into the genetic differentiation of Asian rice.

Improving Parental Lines for Hybrid Rice Development in Indica / Japonica Rice Crosses
Journal of Agricultural Chemistry and Biotechnology, 2019The present study was done at the Experimental Farm of Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt, during 2016 and 2017 seasons to study combining ability, gene action and heterosis for grain yield and some agronomic traits in some lines to be utilized in hybrid rice development.
