Improving Parental Lines for Hybrid Rice Development in Indica / Japonica Rice Crosses

Journal of Agricultural Chemistry and Biotechnology, 2019
The 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.

Physicochemical properties of indica-japonica hybrid rice starch from Chinese varieties

Food Hydrocolloids, 2017
Abstract The knowledge of the properties of indica-japonica hybrid rice starch is limited but critical for different end uses. The starches separated from seven indica-japonica hybrid rice varieties were evaluated for structural, thermal, and pasting properties.

Resistance of Some Chinese Hybrid Rice, Conventional Early Indica and Late Japonica Rice to Magnaporthe Grisea

2004
Thirty isolates of Magnaporthe grisea collected from 18 provinces/cities representing 21 pathotypes and 9 different lineages were inoculated to rice varieties with known resistance genes, some hybrid rice, and conventional early indica and late japonica varieties cultivated in recent years in China.

Response of Japonica and Indica Hybrid cultures of Rice to Nitrogen Manuring

Madras Agricultural Journal, 1962
The results of an experiment laid out to study the differential behaviour of three promising cultures of rice in comparison with their indica parent during 1901- 1962 main season in the Agricultural College wet lands are presented in this paper.

Identification of Indica rice chromosome segments for the improvement of Japonica inbreds and hybrids

Theoretical and Applied Genetics, 2012
Exploitation of heterosis has brought significant advance in plant breeding and agricultural production, although its genetic basis is still poorly understood. In this study, a total of 66 chromosome segment substitution (CSS) lines, derived from a cross between japonica rice inbred line Asominori (as the recurrent parent) and indica rice inbred line ...

Stacking S5-n and f5-n to overcome sterility in indica–japonica hybrid rice

Theoretical and Applied Genetics, 2015
Pyramiding of S5 - n and f5 - n cumulatively improved seed-setting rate of indica-japonica hybrids, which provided an effective approach for utilization of inter-subspecific heterosis in rice breeding. Breeding for indica-japonica hybrid rice is an attractive approach to increase rice yield.

Improvement of Tongil-Type Rice Cultivars from Indica/Japonica Hybridization in Korea

1991
The most crucial factor for the crop improvements lies in the possibility of hybridization between the various genetic sources and thus more diversified genetic resources are needed. Rice has been widely cultivated under diverse climatic, hydrological, and edaphic conditions.

A genetic analysis of low‐temperature‐sensitive sterility in indica‐japonica rice hybrids

Plant Breeding, 1996
AbstractLow‐temperature‐sensitive sterility has become one of the major obstacles in indica–japonica hybrid rice breeding. The objectives of this paper were to evaluate the extent of the fertility reduction and to determine the genetic basis of low‐temperature‐sensitive sterility.

Multi-scale structures and functional properties of starches from Indica hybrid, Japonica and waxy rice

International Journal of Biological Macromolecules, 2017
The structural and functional properties of starches from three rice grains differing in amylose content (19.9, 13.4 and 0.8% for Japonica, Indica hybrid and waxy rice, respectively) were investigated using a range of characterization methods Indica hybrid starch (IHS) had the highest proportion of intermediate (DP 13-24) and long branch chains (DP≥37)

[Characteristics of canopy structure of super high yielding japonica hybrid rice community].

Ying yong sheng tai xue bao = The journal of applied ecology, 2004
In this paper, the characteristics of canopy structure, such as the numbers of seedling, panicle and grain, the distribution of dry matters in different canopy layers and different organs, and the distributions of LAI and of solar radiation in different canopy layers of super high yielding community of japonica hybrid rice were studied, in comparison ...
