Flower organ patterning is accomplished by spatial and temporal functioning of various regulatory genes. We previously reported that Oryza sativa VIN3-LIKE 2 (OsVIL2) induces flowering by mediating the trimethylation of Histone H3 on LFL1 chromatin. In this study, we report that OsVIL2 also plays crucial roles during spikelet development. Two independent lines of T-DNA insertional mutants in th...
Poor spikelet fertility under low temperature (LT) stress during anthesis limits the possibility of high yield potential in indica-japonica hybrid rice, leading to reduced stability of grain yield. However, the cause for it is still unclear. In this study, three indica-japonica hybrid rice cultivars, Yongyou9, Yongyou17 (both cold sensitive), and Yongyou538, and one japonica inbred rice cultiva...
Study of combining ability and heterosis were conducted on 12 F1 hybrids along with seven rice genotypes (three cytoplasmic male sterile lines and four restorer varieties) to know the pattern of inheritance of some morphological traits for selecting superior genotypes. The experiment was carried out according to line x tester mating design, in Sari Agricultural Sciences and Natural Resources Un...
Considering to drought stress importance as most important limiting factor in rice production in world, identification of tolerant genotypes to drought can be a valuable approach to deal with the drought stress. In the present experiment plant materials contains 53 rice genotypes including 31 aerobic and 22 lowland (landrace) rice that were grown in two conditions under drought stress and norma...
Arsenic contamination in soils often leads to groundwater contamination and arsenic toxicity in plants, humans and animals. Plant hormones play a quantitative and qualitative role in the coordination of growth and yield in plants. In this research the effects of gibberellin and sodium arsenate in different genotypes of rice were studied. The work has been conducted as a factorial experiment bas...
This study aimed at evaluating the effect of different planting dates (different ambient temperature conditions) on the characteristics of rice panicle and yield of its cultivars in Khuzestan climate in 2010. The experimental design was a split plot in a Randomized Block Design with four replications. The main factor was the planting date with three dates (May 25th , June 9th , and June 25th ) ...
Ergot, caused by Claviceps purpurea (Fr.:Fr.) Tul., is an important disease of grasses grown for seed. Ergot can be especially severe in Kentucky bluegrass (Poa pratensis L.) seed production, with yield losses estimated as high as 25% (2). Claviceps purpurea invades the ovary, replacing the potential seed with a hard black sclerotium. Sclerotia are typically one to several times longer than the...
Abstract This study aims to examine the good production characteristics and path analyses as well character correlation of highland F4 new plant type lines. The research was conducted in four paddy fields, namely Bittuang, Rantebua, Sesean, Tallunglipu sub-districts at altitudes 650, 850, 1400 1600 meters above sea level North Toraja Tana Regencies. took place from June December 2021 arranged r...
Upland rice (Oryza sativa) is affected by several biotic and abiotic factors that limit the yield potential of cultivars. In relation to water deficiency, development drought tolerant efficient cultivars a priority in breeding programs. With this study aimed evaluate agronomic behavior upland lines subjected different irrigations depths aiming for selection genotypes are responsive deficiency. ...
