High temperature (HT) stress is a major environmental stress that limits plant growth, metabolism, and productivity worldwide. Plant growth and development involve numerous biochemical reactions that are sensitive to temperature. Plant responses to HT vary with the degree and duration of HT and the plant type. HT is now a major concern for crop production(More)
Dianthus caryophyllus L. is an important floricultural crop species throughout the world, specially in Eurasia. The present study was conducted to evaluate the nine Dianthus genotypes, including normal and mutagen treated, to assess the magnitude of variability and to pick up the heritable component of variation present in the quantitative traits. The(More)
Th e experiment was undertaken with an objective to investigate the eff ect of various concentrations of plant growth regulators, i.e., Gibberellic acid (GA3), Kinetin and Indole 3-acetic acid (IAA) on seed germination of Dianthus caryophyllus. Dianthus seeds were soaked in diff erent concentrations (0 ppm or control, 10 ppm, 20 ppm, 30 ppm and 40 ppm) of(More)
A heterogeneous collection of rice genotypes which included seven salt-tolerant rice lines, one salt-sensitive improved line, one wild rice (Oryza rufipogon) and one salt-tolerant wild rice relative (Porteresia coarctata) was screened with ten salt-tolerance-linked simple sequence repeat markers, of which nine were from the Saltol QTL mapped on rice 1st(More)
A total of ten rare indigenous rice landraces of West Bengal were screened for germination potential and seedling growth under varying concentrations of sodium chloride (NaCl) and polyethylene glycol (PEG) solutions as osmotic stress inducing agents. Among the studied rice landraces Kelas and Bhut Moori showed highest degree of tolerance to induced osmotic(More)
Evaluation of eggplant (Solanum melongena) genotypes, including one control check and nine mutants for ten agronomical characters to assess the magnitude of variability and to pick up the heritable component of variation present in the agronomic traits, revealed significant differences among the genotypes for all the studied characters indicating the(More)
