Heterosis and Isozyme Divergence in Indica Rice

Crop Science, 1988
Earlier studies conducted in China indicated an association of heterosis in rice (Oryza sativa L.) crosses with certain esterase and peroxidase isozyme patterns. To search for methods that predict yield heterosis in hybrid rice breeding program at IRRI, we studied isozyme variation of 18 rice cultivars (seven maintainers and 11 restorers of ‘WA ...

Heterotic groups of tropical indica rice germplasm

Theoretical and Applied Genetics, 2014
Four heterotic groups were identified for tropical indica rice germplasm to develop hybrid rice in the tropics based on two studies. Heterotic groups are of fundamental importance in hybrid crop breeding. This study investigated hybrid yield, yield heterosis and combining ability within and among groups based on genetic distance derived from single ...

Rice, Indica (Oryza sativa L.)

2014
Indica varieties, which are generally recalcitrant to tissue culture and transformation, occupy 80 % of rice cultivation area in the world. Therefore, transformation method for indica rice must be improved greatly so that global rice production would take full advantage of cutting-edge biotechnology.

Plant regeneration from protoplasts of Indica type rice and CMS rice

Plant Cell Reports, 1989
Cell suspensions were established from 12 rice genotypes including Indica type, Japonica type and cytoplasmic male sterile (cms) rice lines of both types. 133 green plants were regenerated from protoplasts isolated from an Indica type rice and 15 plants were obtained from a Japonica type cms rice.

HETEROSIS IN EARLY LINES OF INDICA RICE

Madras Agricultural Journal, 1996
Nine parents and twenty hybrids of rice (Oryza satival.) were evaluated for heterosis for days to flowering, plant height, number of productive tillers, panicle length, number of grains per panicle, 100 grain weight and grain yield. Hybrids showing negative heterosis for flowering duration recorded positive heterosis for yield components.

Factors affecting head rice yield and chalkiness in indica rice

Field Crops Research, 2015
Abstract Effects of nitrogen application, genotype, seasons, grain shapes and amylose content (AC) on head rice yield (HRY) and chalkiness were determined in 2012 dry (DS) and wet seasons (WS) in IRRI using 351 indica advanced breeding lines/cultivars from several breeding programs and three N rates (0, 90, and 180 kg ha −1 and 0, 45, and 90 kg ha

Varietal Selection of Some Indica Rice for Production of Puffed Rice

Food and Bioprocess Technology, 2013
Puffed rice is one of the popular snacks in India, which is prepared from pregelatinized milled rice usually by sand roasting method. Twelve varieties of indica rice were screened for the best puffing quality based on their chemical composition and physical characteristics such as amylose content, protein content, length, width, thickness, hardness ...

Agrobacterium-Mediated Genetic Transformation of Indica Rice

Functional genomics in rice has progressed significantly due to the availability of high-quality, well-annotated genome data and the characterization of numerous genes through genetic manipulation. Over the years, various protocols for genetic transformation in rice have been developed and refined.

In vitro flowering of indica rice (Oryza sativa L. spp. indica)

In Vitro Cellular & Developmental Biology - Plant, 2012
Nodal explants of rice cultivar Pathumthani 1 (PT1; short-day photoperiod insensitive) were collected, surface-disinfected, and cultured on modified MS medium under in vitro conditions for 90 d. A total of 60% nodal explants generated flowering plantlets (with one inflorescence per cluster).
