“…For the additive-dominant effect, the characters CA, WC, WHO, and BG were significant (Table 3). It is noteworthy that, for all results of allelic and epistatic interactions, the characters CL, CW, and WHO were in agreement with the results that El-Abd et al (2008), Hassan et al (2011), Sultan et al (2014, Gunasekaran et al (2020), andLingaiah et al (2020) previously reported. They stated that the additive gene effect (a) is important for grain quality characters; it is the only parameter that shows significance for all variables analyzed in both crosses and influences the genetic control of characters related to the attributes of rice grain quality (CA, WC, VW, CL, CW, CL/CW, WHO, and BG).…”

Information about gene action, heritability, heredity, and potential gain estimated by selecting these characters is scarce. This study aims to estimate genetic parameters related to physical attributes of rice (Oryza sativa L.) grain quality. The crosses “BR/IRGA 409″ × “BRS Bojuru” and their reciprocal were performed, obtaining F1 and F2 generations and backcrosses (BC1 and BC2). After obtaining seeds, the experiment was conducted following a completely randomized design with replications determined by the total number of plants of each generation. Total chalky area (CA), white core (WC), vitreous whiteness (VW), caryopsis length (CL), caryopsis width (CW), caryopsis length × width (CL/CW), percentage of whole grains (WHO), and broken grains (BG) were evaluated. The experiment analyzed means and variances and genetic parameters of generations based on a complete model and additive‐dominant model. The physical attributes are inherited quantitatively, and the main genetic effect is the additive. However, there is a great environmental influence on the characters studied. The BR/IRGA 409 × BRS Bojuru cross makes it possible to obtain a greater genetic gain in the selection of chalky grain characters (CA, WC, and VW) as they express a narrower heritability, whereas BRS Bojuru × BR/IRGA 409 makes it possible to obtain a greater genetic gain in the selection of CL, CW, CL/CW, WHO, and BG. Parent plants affect the type of gene action. A gene action of partial dominance, overdominance, and complete dominance occurred among the physical attributes of grain quality.

“…is study investigated the response of different rice cultivars to drought stress based on their physiological and biochemical traits, that is, total chlorophyll, EL, RWC, and FTIR absorption data. PEG was used to evaluate cell membrane permeability and stability, and to evaluate drought tolerance (Amini et al, 2014;Hellal et al, 2018;Sultan et al, 2014). e electroconductivity of aqueous media containing rice leaf discs that were previously water-stressed by exposing to a PEG solution was measured.…”

Drought isa major constraint in many rainfed areas and affects rice yield. We aimed to characterize the physiological changes in rice in response to drought using Fourier transform infrared (FTIR) spectroscopy. Eighty rice landrace seedlings were subjected to drought in the greenhouse using a PEG 6000. Physiological parameters, including total chlorophyll content, relative water content, electrolyte leakage, and biochemical changes were evaluated. Based on the FTIR results, the landraces were divided into three main groups: tolerant, moderately tolerant, and susceptible. Principal component analysis revealed spectral differences between the control and drought stress treatment groups. Lipid, pectin, and lignin content increased after drought stress. The biochemical components of plants at different drought tolerance levels were also compared. The lipid (CH2 and CH3), lignin (C=C), pectin (C=O), and protein (C=O, N–H) contents were the highest in the drought-tolerant cultivars, followed by the moderately tolerant and susceptible cultivars, respectively. Cultivar 17 and 49 were the most tolerant, and the functional groups were identified and characterized using FTIR. Overall, these results will be useful in selecting parental cultivars for rice breeding programs.

Genetic parameters of some characters in rice evaluated with the use of two mating design: diallel and NCIII. Analysis of variance showed significant differences among genotypes for all studied traits in diallel and north NCIII mating design. The results of genetic parameter estimations for diallel mating design revealed the existence of additive-dominance effects in controlling studied traits. Relatively high broad sense heritability observed in Kernel Length (KL) and Final Viscosity (FV) trough diallel mating. The results of genetic parameter estimations for NCIII mating design showed the presence of additive-dominance effects in controlling of all studied traits. This results also indicated that the character's day to 50% of flowering (DTF) and FV controlled by over-dominance of gene effect. Broad-sense heritability was high for all traits and it had highest amount in KL through NCIII. The results of genetic parameters estimation of NCIII mating design approved results of diallel crossing method for FV in the existence of additive-dominance gene effects. Also, for DTF, the results of genetic parameters estimation through NCIII mating design confirmed results of diallel mating design. But it didn't apply for KL. Due to the lack of consistent conform of estimates for some traits, full following to the results of diallel designs will not lead to selecting good traits and effective breeding methods. Thus, according to the results of this study it suggested that the decision to select a breeding method for desirable traits based on the type of gene actions, made by using biparental progeny designs.
