Title

Studying the Relation between Some Agronomic Traits and Dry Matter Remobilization Rate in Canopy of Rice Genotypes

Pages

  617-628

Abstract

 The remobilization of carbohydrates in shoots is one of the effective factors to grain filling in rice. To determine the contribution of dry matter remobilization of shoots in different rice genotypes, a research has been carried out with seven rice genotypes and two controls in RCBD design with three replications during 2017-2018 at rice research station of Shahid Shiroodi in Tonekabon county. Results show that among all genotypes, rate of dry matter remobilization via the flag leaf, stem, and total shoot has differed significantly at (p<0. 01) percent and from other leaves at (p<0. 05) percent level. Mean comparison among the genotypes indicates that the highest dry matter remobilization from flag leaf belongs to genotype 952 with 56 g. m-2. The maximum carbohydrates remobilization in other leaves, stem and total shoots are assigned to genotype 953 at 123, 230, and 398 g. m-2, respectively. Highest grain yield belongs to genotype 952 with 7206 kg. ha-1. correlation analysis results show that grain yield is positively and significantly correlated with dry matter remobilization from flag leaf, stem, and total shoots, as well as 1000-grain weight, having coefficients of 0. 37, 0. 55, 0. 51, and 0. 44, respectively. As a result of yield and dry matter remobilization rate, and the positive and significant correlation between them, both genotypes 952 and 953 are suitable for continuing research activity and introduce a new rice cultivar especially in drought and hot stress conditions at the grain filling stage.
