Screening of rice varieties for direct seeding method
Direct seeding method of rice planting offers several advantages. However, all rice cultivars are not suitable for this practice. In this report forty-three high yield rice varieties and an anoxia/hypoxia tolerant control land race were studied to verify their suitability to establish seedling under anaerobic conditions. The study was conducted in controlled field conditions. The percentage of ...
متن کاملmapping of qtls controlling tolerance to drought and salt stress at germination stage of rice
salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...
متن کاملMolecular Mapping of QTLs Associated with Lodging Resistance in Dry Direct-Seeded Rice (Oryza sativa L.)
Dry direct-seeded rice (DSR) is an alternative crop establishment method with less water and labor requirement through mechanization. It provides better opportunities for a second crop during the cropping season and therefore, a feasible alternative system to transplanted lowland rice. However, lodging is one of the major constraints in attaining high yield in DSR. Identification of QTLs for lo...
متن کاملInterval mapping of QTLs controlling some morphological traits in pea.
A linkage map of pea was constructed based on a 104 RIL population derived from the cross combination Wt10245 x Wt11238. The map, which consisted of 204 morphological, isozyme, AFLP, ISSR, STS, CAPS and RAPD markers, was used for interval mapping of the QTLs controlling the stem length and internode number of pea. In the characterization of a given QTL, we included an identification of its posi...
متن کاملEffects of deficit irrigation and groundwater depth on root growth of direct seeding rice in a column experiment
Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...
