Upland Rice and Allelopathy
Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...
متن کاملComparison of three types of G × E performance plot for showing and interpreting genotypes’ stability and adaptability
A G × E performance (interaction, profile) plot for showing genotype-by-environment data is discussed. Three versions of such a plot are compared: the regular performance plot; the performance plot based on coded data (environment-centered performance plot), in which the environment means of a trait are subtracted from data; and the performance plot based on data standardized in environments (e...
متن کاملGenetic 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 کاملstudy on stability and adaptability of seed yield in spring safflower genotypes under rainfed conditions
in order to study genotype environment interaction (g e) and to identify high yielding and stable genotypes, 17 safflower (carthamus tinctorius l.) genotypes were evaluated in a randomized complete block design with 3 replications, at 9 research stations during four consecutive cropping seasons (2003–06) under rainfed conditions. on the basis of ammi analysis of variance, effects of genotyp...
