general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

Uniformity of stem height in rice directly affects crop yield potential and appearance, and has become a vital index for rice improvement. In the present study, a doubled haploid (DH) population, derived from a cross between japonica rice Chunjiang 06 and indica rice TN1 was used to analyze the quantitative trait locus (QTL) for three related traits of panicle-layer-uniformity; that is, the tal...

The present investigation consisting a set in fashion of line x tester cross combinations were carried out to investigate the inter characters relationship for fifteen In Rice (Oryza staiva L.). experiments conducted during Kharif, 2019-2020at Students Instructional Farm Department Genetics & Plant Breeding, Acharya Narendra Deva University Agriculture and Technology, Nagar (Kumarganj), Ayodhya...

A study was conducted to evaluate the genetic variability parameters, correlation and path coefficient analysis for eight yield related traits in segregating F2 population of an aerobic restorer AR 9-18 × YPK 198 (Donor enhancing genes Gn1a OsSPL14) at ICAR-IIRR, Hyderabad during kharif, 2019. The results indicated that, productive tiller number, grain number per panicle plant showed high PCV G...

A field experiment was conducted at New Area, Department of Millets, Agricultural College and Research Institute, Tamil Nadu University, Coimbatore during Thaipattam (January-February) 2021 on sandy clay loam. Eight treatments were followed with boron nutrition. T1 : Recommended Dose Fertilizer (RDF = N, P, K, S, Zn), T2 RDF + 5 kg/ha ( Soil application), T3 2.5 (Soil application) 0.2% foliar s...

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...

An investigation was carried out during aman season, 2005 at the Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna. Local rice variety Jatai tested against 4 different levels nitrogen viz. 0, 20, 40 and 60 kg N ha-1. The experimental results revealed that significantly affected plant height (cm), number tillers hill-1, weight 1000-grain (g), grain yield (tha-1), biologica...
