Rice varieties with ultra-high yields play an important role in grain production and global food security. However, little information is available on the source–sink relationships that underpin quality ultra-high-yield properties. Photosynthesis, carbohydrate accumulation allocation, vascular bundle morphology, nutrient uptake characteristics were, therefore, compared two ‘super rice’ varietie...
A rice GWAS panel of 281 accessions of japonica rice was phenotypically characterized for 26 traits related to phenology, plant and seed morphology, physiology and yield for 2 years in field conditions under permanent flooding (PF) and limited water (LW). A genome-wide analysis uncovered a total of 160 significant marker-trait associations (MTAs), of which 32 were LW-specific, 59 were PF-specif...
Five populations segregated in isogenic backgrounds and three sets of near isogenic lines (NILs) overlapping in a 362.3-kb region covering heading date gene Hd1 were developed from the indica rice cross Zhenshan97 (ZS97)/Milyang 46 (MY46). They were used to analyze the effects of Hd1 on heading date, plant height and yield traits. In a background of the parental mixtures, the photoperiod-sensit...
Sixty-nine cultivars of rice were examined for fourteen biometrical characteristics to study the degree genetic divergence, heritability and gain as a percentage mean, character relationship path coefficient analysis. Yield per plant reported highest estimate PCV GCV followed by total effective tillers plant, hundred seed weight, number filled seedsper panicle flag leaf length indicating that t...
This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...
The development of new rice varieties is highly dependent on genetic diversity in desirable agronomic traits. Therefore, this study aimed to identify potential genotypes having the characters Korean (Tongil-type) and japonica developed through doubled haploid (DH) technology apply our breeding materials. 35 elite DH lines derived from another culture African along with two local checks were pla...
