Correlation Studies in Rice (Oryza sativa L.)
Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
متن کاملInvolvement of Secondary Metabolites in Response to Drought Stress of Rice (Oryza sativa L.)
In this study, responses of rice under drought stress correlating with changes in chemical compositions were examined. Among 20 studied rice cultivars, Q8 was the most tolerant, whereas Q2 was the most susceptible to drought. Total phenols, total flavonoids, and antioxidant activities, and their accumulation in water deficit conditions were proportional to drought resistance levels of rice. In ...
متن کاملAnalysis of Genetic Variability in Rice Varieties (Oryza sativa L) of Kerala using RAPD Markers
The genetic diversity and phylogenetic relationships of eight different varieties of Rice (Oryza sativa) viz., MO 16, Ptb 43, Palakkaddan Matta, Ptb 40, MO 17, MO 6, Ptb 39 and KTR 2 from Kerala state, South India were analyzed by Random amplified polymorphic DNA (RAPD). Out of twenty 10-mer RAPD primers screened initially, eleven were chosen and used in a comparative analysis of different vari...
متن کاملCharacterization of High-Value Bioactives in Some Selected Varieties of Pakistani Rice (Oryza sativa L.)

متن کاملRoles of plant hormones and anti-apoptosis genes during drought stress in rice (Oryza sativa L.)
We previously identified the rice (Oryza sativa) senescence-associated gene OsSAP which encodes a highly conserved protein involved in anti-apoptotic activity. This novel Bax suppressor-related gene regulates tolerance to multiple stresses in yeast. Here, we show the effects of drought stress on leaf and root tissues of plants over-expressing OsSAP in relation to the levels of phytohormones, ab...
