Sixteen rice genotypes were screened against combined salinity and submergence stresses to find out potential salt-submergence tolerant genotypes. Rice seedlings subjected stress including two levels viz., EC-6 dSm-1 EC-8 for 10 days. Imposition of considerably decreased the growth parameters in seedlings, however ACM-18, ACM-35, RC-251 demonstrated maximum value attributes such as leaf live (%...

Many studies have shown that local landraces are found to be better adapted to changing climatic conditions. The screening of local land races is one of important processes to detect drought tolerant behavior of crop species to further verify in similar field situation and genomic/molecular level studies. In 2009 for main season rice, a study was done to identify different land races of rice in...

Blast caused by Pyricularia oryzae is one of the major constraints limiting rice production globally. Study was undertaken at TNAU, India using a set of selected genotypes including cultivated varieties and (Near Isogenic Lines) NILs and they were screened for blast resistance both genotypically and phenotypically. Genetic diversity was studied among the genotypes and those which are diverse in...

In semiarid regions, soil salinity, like drought, restricts crop productivity, causing food shortages among most inhabitants—the smallholder subsistence farmers. Seasonal wetlands formed in these regions during the rainy seasons could be utilised for rice (Oryza spp.) cultivation to increase security, but is sensitive salinity. Field and greenhouse-pot experiments were performed at University o...

Optimum growing temperature is necessary for maximum yield-potential in any crop. The global atmospheric changing more rapidly and irregularly every year. High at the flowering/reproductive stage rice causes partial to complete pollen sterility, resulting significant reduction grain yield. Green Super Rice (GSR) an effort develop elite type that can withstand multiple environmental stresses mai...

A study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. Two lines were crossed with five testers in line × tester fashion to produce 10 F1 hybrids. Analysis of variance revealed significant differences among genotyp...

The present research aims to study the association and allelic diversity of linked microsatellite markers to grain quality QTLs of 84 exotic rice genotypes. To this end, 9 microsatellite markers (RM540, RM539, RM587, RM527, RM216, RM467, RM3188, RM246, RM5461) were used in which a total of 61 alleles were identified with a mean of 6 alleles per locus. The polymorphism information content (PIC) ...
