Genomic regions responsible for seminal and crown root lengths identified by 2D & 3D root system image analysis

Genetic improvement of root system architecture is a promising approach for improved uptake of water and mineral nutrients distributed unevenly in the soil. To identify genomic regions associated with the length of different root types in rice, we quantified root system architecture in a set of 26 chromosome segment substitution lines derived from a cross between lowland indica rice, IR64, and upland tropical japonica rice, Kinandang Patong, (IK-CSSLs), using 2D & 3D root phenotyping platforms.

Ratnagiri 8, a medium slender high yielding rice variety for six states of India

The rice variety Ratnagiri-8 (IET 25493; RTN 28-1-5-3-2) was evolved from the cross between IR64 and Karjat 184 using former parent as female through pedigree method of selection. The above variety is midlate in duration (135-138 days in Kharif), Semi-dwarf (102-110 cm plant height). Ratnagiri 8 rice variety recorded 38.52% higher grain yield over HYV’s medium slender check Palghar 1 pooled over five years testing in Station Trial.
