Traditional and Modern Plant Breeding Methods with Examples in Rice (Oryza sativa L.)

Correlation Studies in Rice (Oryza sativa L.)

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Genetics, Physiological Mechanisms and Breeding of Flood-Tolerant Rice (Oryza sativa L.).

Flooding of rice fields is a serious problem in the river basins of South and South-East Asia where about 15 Mha of lowland rice cultivation is regularly affected. Flooding creates hypoxic conditions resulting in poor germination and seedling establishment. Flash flooding, where rice plants are completely submerged for 10-15 d during their vegetative stage, causes huge losses. Water stagnation ...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

Roles of plant hormones and anti-apoptosis genes during drought stress in rice (Oryza sativa L.)

We previously identified the rice (Oryza sativa) senescence-associated gene OsSAP which encodes a highly conserved protein involved in anti-apoptotic activity. This novel Bax suppressor-related gene regulates tolerance to multiple stresses in yeast. Here, we show the effects of drought stress on leaf and root tissues of plants over-expressing OsSAP in relation to the levels of phytohormones, ab...

Evaluation of Some Morphophysiological Traits and Growth Indices of Rice (Oryza sativa L.) in Irrigation Methods

In order to investigate the analysis of growth indices and morphophysiological traits of rice, an experiment in the form of statistical split plots design with three levels of irrigation and six foliar application with three replications was conducted at Deputy of Rice Research Institute (Mazandaran- Amol) in 2017. By measuring the total dry weight and leaf area six times during rice growth, th...
