in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...

The effect of seedling age and number per hill on yield contributing characters Transplant Aman rice in Khulna region was investigated from July to December 2002.The treatments included the experiment consisted 4 (viz.15, 25, 35 45 day old seedling) 5 hill-1 (viz. 1, 2, 3, 5). It found that 25 produced tallest plant (118.87 cm), highest total tiller (33.02), effective (30.37), longest panicle l...

Genetic diversity of 40 traditional Bangladeshi rice genotypes was studied under rainfed condition through Mahalanobis D statistic for grain yield and yield contributing characters. The genotypes were grouped into six clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intra-cluster dist...

To determine the effect of inorganic N fertilizer on the incidence of yellow stem borer (YSB), Scirpophaga incertulas Walker and on grain yield, yield attributes and bio-chemical characters of local paddy cultivar Tulaipanji, a field experiment for three consecutive years (2007-2009) was carried out by randomized block design in pesticide untreated field. Treatments comprised of seven different...

Advanced backcross introgression lines (BILs) developed from crosses of Oryza sativa var. Swarna/O. nivara accessions were grown and evaluated for yield and related traits. Trials were conducted for consecutive three seasons in field conditions in a randomized complete block design with three replications. Data on yield traits under irrigated conditions were analyzed using the Additive Main Eff...

to identify qtls controlling grain yield and yield components, an f2 population consisting of 188 plants derived from the cross between two rice pure lines, binam and kadous, were grown in research field of faculty of agricultural sciences, university of guilan, rasht, iran, in 2008, and were recorded for 9 important traits related to grain yield. to construct linkage map, 85 marker of ssrs and...

An experimental trial of nine rice genotypes was conducted in the Agronomy field Institute Agriculture and Animal Science (IAAS) Paklihawa Campus under a randomized block design layout with three replications from July to November 2022. The aim study genetic variability analyze character association yield yield-attributing components their direct indirect effect on grain reproductive drought st...

Grain yield is a quantitative trait, which determined by several agronomic traits. Unfortunately, there little information about the genetics behind components in US rice cultivars. The objectives of present study were to (1) conduct QTL identify chromosome (chr. hereafter) regions associated with traits two U.S.-developed cultivars and (2) candidate genes major related Four evaluated summer 20...
