Rice is one of the most important food crops, thus identification of definitive traits on the yield can be used in breeding programs. In order to determine the best suitable morphological markers for selection of superior genotypes, seeds of 15 rice genotypes including 5 varieties (namely: Binam, Dasht, Neda, Mashhad Domsiah and IR62871-175-1-10) and their 10 F1 hybrids of corresponding variate...
In order to study the effects of rate and time of nitrogen application on vegetative characters, i.e., yield and yield components of rice (Zayandeh-rood variety), an experiment was conducted at Isfahan University of Technology research farm during summer 1996. Four N rates including (60, 90, 120 and 150 KgN/ha) and four splitting form (1- all N applied before transplanting 2- 1/3 N applied befo...
The results indicated that the seed yield per plant showed a significant positive correlation with most of traits like days to 50% flowering, height, filled grains panicle, number spikelet fertility, flag leaf width, numbers tillers plant, effective panicle length and 100 weight, representing importance these for development great yielding varieties in contrast trait sterility has been reported...
This study aimed to investigate the correlations among yield and component traits estimate direct indirect effects of these on grain in rice. The experiment was conducted during kharif 2022. Correlation coefficients path were analyzed determine relationships between seed yield. results showed significant positive such as effective tillers per plant, total number filled grains, spikelet fertilit...
A study of genetic variation and interrelationship among grain yield and its component traits in rice (Oryza sativa L.) was carried out using 64 exotic rice genotypes. Maximum genotypic and phenotypic variance was exhibited by number of spikelets per panicle followed by plant height and days to maturity. The maximum GCV and PCV was exhibited by number of spikelets per panicle followed by number...
This study was carried out in order to determine the more suitable seedling age on rice cultivars in Chaparsar Rice Research station of Mazandaran province in 2009. This experiment was laid out as split plot in a randomized complete block design with 3 replications. The main plots were seedling age with four levels (20, 33, 37 and 40 days) and sub plots were rice cultivars (Hashemei, Khazar, hy...
In order to investigate the effect of water deficit tension on different growth stages on yield, yield components and produced grain quality of sorghum seeds cultivars, an experiments was performed as split plots based on randomized complete blocks design with four replications in Isfahan Ghiam Cultivation and Cattle Farm Company in 2017. The main factor including irrigation cut at four levels...
Six parent diallel cross without reciprocal was studied to investigate the genetic behavior of different agronomic traits in rice. The analysis of Wr-Vr graph showed that panicle length, thousand grain weight and grain yield per plant did not follow the additivedominance model indicating epistatic gene action responsible for the expression of these traits. All other traits under the study were ...
Rice (Oryza sativa cv. Jindao 1187) was grown in open-top chambers which contained ambient and enriched C02. C02 elevation stimulated rice tillering during early vegetative stage. However, panicle dry weight per plant did not change at maturity stage. Root biomass was enhanced by high COz. Root / shoot ratio was increased under high C02 at maturity, indicating more carbon allocation to the belo...
