Salinity is one of the most serious factors limiting productivity rice crops, with adverse effects on germination, plant vigor and crop yield. A population 300 F 5:6 recombinant inbred lines (RILs), which was derived from a cross between IR29 (indica sensitive to salinity) Hasawi (Saudi cultivar showing salt tolerance), evaluated at young seedling stage under hydroponic conditions an EC 12 dsm -1 . Such RIL when fixed can be repeatedly used for investigating QTLs various phenotypes different...
Abstract Salt stress is a menace to rice production and threat food security worldwide. We evaluated 308 F 4 families from Sahel 317/Madina Koyo for tolerance salt at the early seedling stage. To better understand genomic regions controlling in population, we genotyped progenies two parents using single nucleotide polymorphism (SNP) markers regressed genotypic data on their phenotype detect QTLs. An average reduction of 63.4% was observed all fitness-related traits among families. A total 46...
Rice (Oryza sativa L) is one of the most important staple food worldwide with a global production estimated at around 800 million metric tons for paddy rice in 2021. However, this hampered by several factors, such as land salinity. In study, 230 F2:3 lines Sahel 328/NERICA-L-9 mapping populations were evaluated their tolerance to salinity young seedling stage an electrical conductivity (EC) equivalent 12 dSm−1. All parameters investigated negatively affected under saline conditions compared...
Anther indehiscence in certain wide crosses combines male sterility with stigma exertion, a phenomenon that is desirable for hybrid rice seed production. This study sought to identify chromosomal region(s) combine anther exerted stigmas. A mapping population consisting of 189 BC
Soil salinity is a major abiotic stress that affects rice production. It can reduce yield drastically and result in total crop failure. The objectives of this study are to determine the genetic diversity within thirty-six accessions identify genotypes tolerant salinity. Thirty-six including three check varieties were sown experimental pots their leaves harvested for DNA extraction. Screening was done with 31 simple sequence repeats (SSRs) primers, which 14 markers salt tolerance, 2 primers...
