Identification of phosphorus efficient rice cultivars under low P nutrition through hydroponic based screening

Autor: D. S. Kekulandara, P. C. G. Bandaranayake, D. N. Sirisena, W. L. G. Samarasinghe, L. D. B. Suriyagoda

Publikováno v: Tropical Agricultural Research, Vol 30, Iss 3, Pp 43-53 (2019)

Phosphorus (P) is one of the major nutrients required by plants. A higher portion of P in lowland rice soils is found in unavailable forms due to fixation. Therefore, continuous application of P fertilizer to rice (Oryza sativa L.) is needed to obtai

Phenotypic screening of rice varieties for tolerant to salt stress at seed germination, seedling and maturity stages

Autor: R. M. N. H. Senanayake, H. M. V. G. Herath, I. P. Wickramesinghe, U. A. K. S. Udawela, D. N. Sirisena

Publikováno v: Tropical Agricultural Research, Vol 29, Iss 1, Pp 90-100 (2017)

Salinity affects all growth stages of rice in varying degrees starting from germination up to maturation. The present study was conducted to screen the commonly cultivated rice varieties in salinity affected areas in Sri Lanka against salt stress. Sc

Quantitative genetic assessment of the phosphorus deficiency tolerance in selected F2 progenies of rice (Oryza sativa L.) genotypes in Sri Lanka

Autor: Y. C. Aluwihare, R. Lelwala, D. R. R. P. Dissanayake, M. D. M. Chamikara, D. N. Sirisena, W. L. G. Samarasinghe, S. D. S. S. Sooriyapathirana

Publikováno v: Tropical Agricultural Research, Vol 28, Iss 1, Pp 1-25 (2016)

Phosphorus deficiency (PD) is a limiting factor in rice farming and hence PD tolerant varieties are essential. The PD tolerant quantitative trait loci (QTL) have been identified using the rice landraces Kasalath and Nipponbare. However, PD tolerant S

Screening of segregating F2 progenies and validation of DNA markers through bulk segregant analysis for phosphorous deficiency tolerance in rice

Autor: Y. C. Aluwihare, M. D. M. Chamikara, N. N. H. Karannagoda, D. R. R. P. Dissanayake, R. A. G. B. Ranawaka, M. I. Tennakoon, D. N. Sirisena, W. L. G. Samarasinghe, C. K. Weebadde, S. D. S. S. Sooriyapathirana

Publikováno v: Ceylon Journal of Science, Vol 45, Iss 2, Pp 87-101 (2016)

Phosphorous deficiency (PD) tolerance is a polygenic trait. The underlying genetics of PD tolerance trait is important to provide the basis for detecting Quantitative Trait Loci (QTLs) and validating markers that could be used in Marker Assisted Bree

Temporal tillering behavior of Sri Lankan elite rice varieties in response to phosphorus availability

Autor: D. S. Kekulandara, P. C. G. Bandaranayake, D. N. Sirisena, W. L. G. Samarasinghe, L. D. B. Suriyagoda

Publikováno v: Tropical Agricultural Research, Vol 28, Iss 2 (2017)

Tillering is closely related to environmental conditions including the accessibility to nutrients. Phosphorus (P) availability affects tillering dynamics in rice. A hydroponic experiment was conducted to identify the tillering dynamics of forty eight
