Heterosis breeding in rice (Oryza sativa L.)

Theoretical and Applied Genetics, 1982
Studies conducted at the International Rice Research Institute (IRRI) during 1980 and 1981 have shown up to 73% heterosis, 59% heterobeltiosis and 34% standard heterosis for yield in rice. The latter was estimated in comparison to commercial varieties: IR36 and IR42 (yield 4-5 t/ha in wet season trials and 7-8 t/ha in dry season trials).

Strigolactones shape the rhizomicrobiome in rice (Oryza sativa)

Plant Science, 2019
The rhizomicrobiome helps the host plant to better adapt to environmental stresses. In contrast, plant-derived metabolic substances, including phytohormones, play an active role in structuring rhizomicrobiome. Although strigolactones (SLs), a group of phytohormones, serve as potential rhizosphere signaling molecules, their contributions in shaping the ...

Artificial Chromosomes in Rice (Oryza sativa)

Current Protocols in Plant Biology, 2016
AbstractChromosomes are the carriers of genetic material in biological organisms. Each chromosome has three essential components: a centromere, telomeres, and origins of replication. The understanding of the essential structural and functional organization of chromosomes has made it possible to produce artificial chromosomes (ACs), which are human ...

Transgenic Rice (Oryza sativa)

2000
Rice (Oryza sativa L.) is one of the most important cereals in the world, and extensive studies have been carried out on tissue culture and transformation (see Hasezawa et al. 1989; Bajaj 1991; Uchimiya and Toriyama 1991). However, transformation of rice by Agrobacterium-mediated gene transfer has not been successful until recently, and gene transfer ...

Circular RNA in Rice (Oryza sativa)

2021
Circular RNAs are a group of non-coding RNAs with a closed-loop structure that produce via the atypical alternative splicing event in all eukaryotic species. As a result of current advances in sequencing technologies and data analysis tools, an enormous number of circRNAs have been recognized in different animal and plant species.

HETEROSIS IN RICE (Oryza sativa L.).

Madras Agricultural Journal, 1987
A study was made to assess the extent of oxploitable heterosis in a 7 x 7 diallel. The results indicated that almost all combinations involving IR 8 as one of the parents pos- sessed high mean and significant heterosis for yield but none of thec ombinations excelled it, indicating non-existence of exploitable heterosis with the parents under study ...

Kinematic Growth Analysis of Rice (Oryza sativa) Leaf

2021
Rice leaves have a consistent spatial and temporal organization of cell division and expansion, which leads to typical cell length profiles along the longitudinal axis. The growth of rice leaves is usually studied during a steady-state period when leaf elongation rate is constant and the spatial distribution of cell length is temporally invariable.

Chlorophyll deficiencies in rice (Oryza sativa)

Proceedings / Indian Academy of Sciences, 1935
Nine types of Mendelian chlorophyll deficiencies consisting of both unicoloured and variegated forms have been described and their inheritance discussed. Some of these like the “zebra-marked”, lutescent and certain variegated forms are recorded for the first time in rice.
