Hakoda, H.; Inouye, J., 1988: Genetic diversity of deep water rice oryza sativa l. originated in asian countries on the basis of esterase isozyme loci. Esterase zymograms of deep water rice varieties which originated in seven Asian countries were examined. Nine of 12 genotypes which are expected from the combinations of the five major bands (Est-1, Est-2s, Est-2F, Est-3S, Est-3F) were found in th...

Ikehashi, H.; Araki, H., 1987: Screening and genetic analysis of wide-compatibility in F1 hybrids of distant crosses in rice, Oryza sativa L. Out of 80 varieties screened, Calotoc, CPSLO17 and Ketan Nangka produced fully fertile F1 progeny on crossing with both indica and japonica testers, and were designated wide-compatibility varieties (WCVs). Genetic analysis of these WCVs suggested...

Teng Sheng; H.Z.angHua; Zhang XueQin; Yan QiuSheng, 1997: Identification of somatic hybrids between cultivar rice and wild rice by isozyme analysis. Hybrids pf9252, pf9279 and pf92100 developed from from protoplast fusion between Oryza sativa cv. 02428 and O. officinalis were identified by peroxidase (POX) and esterase (EST) isoenzymes. It was confirmed that pf9252 and pf9279 were true somatic...

Watanabe, H.; Saigusa, M.; Morita, S., 2006: Identification of Casparian bands in the mesocotyl and lower internodes of rice (Oryza sativa L.) seedlings using fluorescence microscopy. The mesocotyl and lower internodes of seedlings are underground organs that play a possible role in water absorption and transport. The aim of this study is to reexamine and understand further the anatomy and morphology of mesocotyls and lower int...

L.C.uanGen; Zou JiangShi; Ikehashi, H., 2000: Gamete abortion locus detected by segregation distortion of isozyme locus Pgi1 in indica-japonica hybrids of rice (Oryza sativa L.). In an attempt to stabilize the pollen fertility of indica-japonica hybrids of rice by the incorporation of segregation-distortion-neutral alleles, a locus causing distorted segregation of male gamete in indica-japonica hybrids was identified with...

Duan, X.L.; Chen, S.B., 1988: Genetic variation of the esterase isozymes in rice (Oryza sativa) X sorghum (Sorghum vulgare) hybrids. O. sativa cv. Yinfang X S. vulgare [S. bicolor] cv. Hengjiali hybrid and backcross generations were analysed for variation in esterase isoenzymes using PAGE. The results showed that a particular band, inherited from the sorghum parent, appeared in...

Shanthi, S.; Nadarajan, N.; Backiyarani, S., 1997: Identification of superior hybrids in lowland rice (Oryza sativa L.). Fifteen hybrids and their 13 parents were evaluated during kharif 1992-93 for heterosis for grain yield and its contributing traits, viz., days to 50% flowering, plant height, productive tillers per plant, ear length, grains per ear, 100-grain wei...

Wang, X.-Ming; Zhou, J.; Yang, Y.; Yu, F.-Bo; Chen, J.; Yu, C.-Lang; Wang, F.; Cheng, Y.; Yan, C.-Qi; Chen, J.-Ping, 2013: Transcriptome Analysis of a Progeny of Somatic Hybrids of Cultivated Rice Oryza sativa L and Wild Rice Oryza meyeriana L With High Resistance to Bacterial Blight. Previously, we successfully introduced the bacterial blight (BB) resistance trait from Oryza meyeriana into Oryza sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a near-isogenic line n...

Li, W.; Liang, H.; Sun, Y.; Yan, Q.; Zhang, X., 1996: Identification of somatic hybrids between rice cultivar and wild Oryza species by RAPD. The somatic hybrids between rice cultivar and wild Oryza species were obtained by the PEG and electrical fusion method. The somatic hybrids were identified with PAPD. It was verified that the genome of somatic hybrids contained some genomes from b...

Santhy, V.; Dadlani, M.; Mohapatra, T.; Sharma, S.P., 2003: Identification of the parental lines and hybrids of rice (Oryza sativa L.) using RAPD markers. Application of RAPD markers for the identification of three rice (Oryza sativa L.) hybrids and their parental lines i.e. CMS female parent (A line), maintainer (B line) and pollen parent (R line), was tested using 17 random oligonucleotides (Opero...
