Investigation and genetic analysis of yield traits and drought tolerance of Oryza rufipogon using advanced backcrossing inbred populations

Rice (Oryza sativa L.) is one of the staple cereal crops of the world and it is one of the main sources of carbohydrates for nearly one-half of the world's population. So, an increase in rice yield to satisfy human needs is a pressing requirement. Agronomic characters such as high plant, length of panicle, length of flag leaf, number of seed per panicle, the weight of thousand rice, length and width of rice and tolerance to salt are the deciding factor for yield in rice.

Summary of Philosophy doctoral theses in Agricultural biotechnology: Using of molecular markers to study of the improvement of the chalkiness ratio in high-yielding rice varieties (Oryza Sativa L.)

To generate the novel rice lines/varieties with high-yielding and low chalkiness ratio for the improvement of chalkiness traits of rice grains on the high-yielding rice varieties with the help of Microsatellitemolecular markers linked with the genes that control chalkiness characteristics on chromosome 7 of rice.

Symptomatology and disease intensity of various Pyricularia grisea isolates in different hosts

Rice (Oryza sativa L.) is an important cereal crop and prone to many diseases out ofwhich, rice blast caused by Pyricularia grisea is of significant economic importance due to its destructive nature leading to serious yield loss. Blast infected leaves of rice, Panicum grass and finger millet were collected from different fields of OUAT farm, Bhubaneswar.

Source and sink activity during reproductive phase of rice (Oryza sativa L.)

Source and sink activity measured after anthesis in six poplar rice cultivars. The experiment was laid in randomized block design with six cultivars MTU-1001, MTU1010, MTU-7029, BPT-2231, BPT-3291 and BPT-5204 replicated four times. After anthesis, top three leaves separately, top three internodes collectively, panicle axis and grain of main culm were sampled at seven day interval and analysed for biochemical parameters that serve remobilization of nutrients. During the initial and later halves of the sampling, there was a shift in higher amylase activity from third to flag leaves.

Báo cáo khoa học: Binding afﬁnities and interactions among different heat shock element types and heat shock factors in rice (Oryza sativa L.)

Binding of heat shock factors (Hsfs) to heat shock elements (HSEs) leads to transcriptional regulation of heat shock genes. Genome-wide, 953 rice genes contain perfect-type, 695 genes gap-type and 1584 genes step-type HSE sequences in their 1-kb promoter region.
