Salinity has a significant impact on rice production in coastal, arid and semi-arid areas in many countries, including countries growing temperate rice, such as Kazakhstan. Salinity tolerant temperate japonica rice accessions were identified in this study, these accessions are important resources for breeding programs. SNPs located in the promising QTLs and candidate genes could be used for future gene validation and marker assisted selection.

Rice is one of the most important food crops in the world and mainly cultivated in paddy feld by transplanting seedlings. However, increasing water scarcity due to climate change, labor cost for transplanting, and competition from urbanization is making this traditional method of rice production unsustainable in the long term.

Balancing the yield, quality and resistance to disease is a daunting challenge in crop breeding due to the negative relationship among these traits. Large-scale genomic landscape analysis of germplasm resources is considered to be an efficient approach to dissect the genetic basis of the complex traits.

Low temperature is a limiting factor of rice productivity and geographical distribution. Wild rice (Oryza rufipogon Griff.) is an important germplasm resource for rice improvement. It has superior tolerance to many abiotic stresses, including cold stress, but little is known about the mechanism underlying its resistance to cold.

Screening of red-kernelled deep water rice germplasm of Assam, India for disease and pest resistance
The germplasm, five germplasm viz. Arg Bao, Basudev Bao, Dal Bao, Rayada B8 and Sarmora Bao showed MR reaction to both diseases and pest tested. These germplasm may be used as donors in resistant DWR breeding programmes against the tested pathogens and pest.

The primary step to biofortify rice can be successfully achieved after screening the folate distribution in rice germplasm accessions. The extent of natural variation in folate content needs to be determined to employ selection of genotypes or breeding for enhancement of folate levels. As such, there is very limited study in India on the genetic variation in rice germplasm for folate content. Selection of rice genotypes with higher folate content is the first step towards enhancement of folate levels in rice based foods.

The present investigation was carried out to estimate different genetic parameters in ricebean germplasm of NW Himalayas. Forty germplasm lines of rice bean were evaluated for yield and its components in Kharif, 2015 at the experimental farm of CSKHPKV, Palampur. High PCV and GCV was observed for seed yield/plant, plant height, pod length, pods/cluster and clusters/plant indicating the role of these characters for effective selection.

Colocasia or taro (Colocasia esculanta L.) is one of the important tuber crops, which has been grown by farmers in rain-fed ecosystem and considered as an important food crop after rice in Nagaland. The characterization of taro from 11 districts of Nagaland, Northeast India has been analyzed using microsatellite markers. Twenty eight microsatellite markers were used to analyze 50 accessions of taro collected from 11 district of Nagaland.

The present study was conducted at the experimental farm of ICAR Research Complex for Eastern Region, Patna, India in Kharif season 2016 with an objective to identify sheath blight and bacterial leaf blight disease resistance rice genotypes under submergence condition in middle Indo Gangetic Plain. The disease incidence was observed at maturity stages during Kharif season 2016. The incidence of sheath blight and bacterial leaf blight of paddy ranged from 18.6 to 39.0% and 15.3 to 34.0%, respectively.
