Rice (Oryza sativa) breeding strategies for grain biofortification

Biofortification is a process in which plant species are improved in order to raise the nutritional content of the product consumed. The following are some of the main techniques that can be introduced in plant breeding programs in order to improve the nutritional quality of the food to be produced. The rice breeding for higher Fe and Zn content in grain, rice breeding for higher β-carotene content in the grain,...

Preventive effect of black rice antioxidant extract on oxidative stress induced by ethyl alcohol

The present study investigated the black rice ethanolic extract (BREE) protective effect as natural antioxidants against oxidative stress induced by ethyl alcoholic (EA) in male rats. BREE flavonoids and phenols were determined by high performance liquid chromatography (HPLC). The study was conducted on 40 male Wistar rats weighing 170±2 g, the animals divided into 4 equal groups. The first group was given...

Production and purification of extracellular pullulanase by Klebsilla aerogenes NCIM 2239

The present study was carried out to optimize the production of pullulanase from Klebsilla aerogenes NCIM 2239, a new strain of the bacterium. The organism was screened for its ability to synthesize and secrete extracellular pullulanase, by analysis of pullulan degrading activity. Environmental (pH and temperature) and nutritional (carbon and nitrogen) factors influencing growth and product formation were optimized...

Heterosis, heterobeltiosis, narrow-sense and broad-sense heritabilities for Phytophthora megakarya tolerance in two populations of Theobroma cacao L.

A 2x2 diallel mating design was set up to estimate quantitative genetic parameters after leaf artificial inoculation tests in nursery and field for three consecutive years. F12 and F40 families of two reciprocal crosses viz., F12: ♀SCA12 × â™‚ICS40 and F40: ♀ICS40 × â™‚SCA12 were used to study heterosis (mid-parent), heterobeltiosis (better-parent), heritability (narrow-sense and broad-sense) and to...
