Empowering rice breeding with NextGen genomics tools for rapid enhancement nitrogen use efficiency.

As rice has no physiological capacity of fixing nitrogen in the soil, its production had always been reliant on the external application of nitrogen (N) to ensure enhanced productivity. In the light of improving nitrogen use efficiency (NUE) in rice, several advanced agronomic strategies have been proposed. However, the soared increase of the prices of N fertilizers and subsequent environmental downfalls caused by the excessive use of N fertilizers, reinforces the prerequisite adaptation of other sustainable, affordable, and globally acceptable strategies.

Floral volatile composition of variants developed through colchicine.

Jasmines are commercially grown for their fragrant flowers and essential oil. The present study investigates the composition of the volatile compounds from flowers of cv. Ramanthapuram Gundumalli and its variants that were evolved through colchicine.

Development and characterization of gamma ray and EMS induced mutants for powdery mildew resistance in blackgram.

Purpose: During post-rainy and rice fallow cropping seasons, popular blackgram varieties are severely affected by powdery mildew leading to severe yield loss. The lack of natural genetic variability for powdery mildew resistance in blackgram germplasm warrants mutation breeding. Hence, in this study, blackgram cultivar CO6 was mutagenized with gamma ray and ethyl methanesulphonate (EMS) to create variability for powdery mildew resistance.
