Genetic Diversity of Drought Tolerant Upland Rice (Oryza sativa L.) Genotypes
Genetic divergence of thirty three drought tolerant rice (Oryza sativa L.) genotypes were studied through Mohalanobis’s D and principal component analysis for twelve characters. The genotypes were grouped into seven clusters. The cluster I and II were comprised of the maximum number of genotypes (eight) in each followed by cluster V containing five genotypes. The highest inter-cluster distance ...
متن کاملMicrosatellite markers linked to drought resistance in rice (Oryza sativa L.)
Among the abiotic stresses, drought is a serious limiting factor that reduces rice production and yield stability in rainfed ecosystems. Conventional breeding for drought resistance is slow in attaining progress due to poor understanding of genetic control of drought resistance. Molecular markers help in identification of quantitative trait loci (QTLs) associated with drought resistance traits ...
متن کاملCorrelation 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 کاملMapping QTLs for Physiological Traits Associated with Drought Tolerance in Rice (Oryza Sativa L.)
Drought is the most important limiting factor for crop production and it is becoming an increasingly severe problem in many regions of the world [1]. According to FAO statistics, the percentage of drought affected land areas more than doubled from the 1970s to the early 2000s in the world [2]. Drought is a world-spread problem seriously influencing grain production and quality and with increasi...
متن کاملGuttation fluid as a physiological marker for selection of nitrogen efficient rice (Oryza sativa L.) genotypes
A field experiment was conducted during the rainy season of 2008 and 2009 to use guttation fluid as a physiological marker for the screening of more nitrogen efficient rice genotypes on the basis of relationship between Guttation Fluid (GF) oozed by leaf tip and nitrogen use efficiency (NUE), grain yield (GY) and biological yield (BY) amongst five rice (KRH-2hybrid, Kasturiaromatic, Krishna Ham...
