Extended Abstract Introduction and Objective: Due to the very high diversity among the genotypes of quinoa (Chenopodium quinoa), it has shown a very high adaptability and stability in different climates. Therefore, this experiment was performed to investigate the morphological and genetic diversity of 14 quinoa genotypes and compare them with the control genotype of the region (Titicaca). Ma...
In general, the fertility and kernel weight of inferior spikelets of rice (Oryza Sativa L.) are obviously lower than those of superior spikelets, especially under abiotic stress. However, different responses to heat stress are seemed to show between the superior and inferior spikelet, and this response is scarcely documented that the intrinsic factors remain elusive. In order to reveal the mech...
seven rice varieties (hassani, deilmani, sepidrod, shahpasand, saleh, neda, and irfaon215) along with their complete diallel progenies were grown in a randomized complete block design of three replications in the growing seasons of 2006 and 2007 and were evaluated for the quantitative traits of: number of days to flowering, flag leaf length, width and area, plant height, panicle length, extrusi...
The qTSN4 was identified as rice QTL (Quantitative Traits Locus) increasing total spikelet number per panicle and flag leaf area but potentially reducing panicle number depending on the environment. So far, this trade-off was mainly observed at grain maturity and not specifically studied in details, limiting the apprehension of the agronomic interest of qTSN4. This study aimed to understand the...
1000-Grain weight and spikelet number per panicle are two important components for rice grain yield. In our previous study, eight quantitative trait loci (QTLs) conferring spikelet number per panicle and 1000-grain weight were mapped through sequencing-based genotyping of 150 rice recombinant inbred lines (RILs). In this study, we validated the effects of four QTLs from Nipponbare using chromos...
Water deficit caused a serious threat to crops, especially panicle development at reproductive growth phase. We investigated grain yield components and gene expression profiles of panicle among tolerant and sensitive rice in response to drought stress. Panicle morphologies exhibited that secondary branches per panicle were more severely affected as compared to primary branches per panicle. More...
The intensity of trait association and genetic variability yield attributing variables in 217 rice genotypes was investigated during kharif 2018. existence among the demonstrated by analysis variance, which recorded significant differences for all seven studied parameters. estimation indicated that full grain number per panicle (37.2 % 34.1 %) & single plant (24.7 20.55 had highest phenotyp...
Facilitate the selection procedure to improve performance of new genotypes of rice is essential. In present study in order to evaluate relationship between grain yields with other agronomic traits, a global rice collection including 100 accessions was seeded in an incomplete block design (triple lattice 10×10). Afterward, grain yield and 14 morphological traits were evaluated. Correlation coeff...
Panicle architecture determines the number of spikelets per panicle (SPP) and is highly associated with grain yield in rice (Oryza sativa L.). Understanding the genetic basis of panicle architecture is important for improving the yield of rice grain. In this study, we dissected panicle architecture traits into eight components, which were phenotyped from a germplasm collection of 529 cultivars....
