Rice was grown in an open-field Gangetic soil condition with arsenic amended irrigation water in experimental plot at Institute of Environmental Science of Rajshahi University to see the effect of arsenic (As) on growth and yield of rice (Oryza sativa L.). A popular aman rice variety named BR-11 was cultivated with arsenic amended irrigation water (0 mg, 0.1 mg, 0.5 mg, 1.0 mg, 2.0 mg and 4.0 m...

The field experiments with thirty genotypes were conducted during June to October month of kharif, 2018 and 2019, assess extent variability under aerobic condition. sown dry direct seeded condition using randomized block design (RBD) three replications. Each genotype was in single row 5 m length spacing 20 cm between rows 15 plants. Data recorded for 22 characters including different morphologi...

The present study consists of 21 rice genotypes including one check variety that were evaluated in 2021 to genetic variability, correlation and path coefficient for thirteen quantitative characters. Observation recorded the variability parameters, yield its attributing traits. On basis mean performance MTU-1224 was found be superior grain per hill followed by, BPT-329, KNM-118 MTU-1001 give hig...

Although flowering time is often associated with plant size, little is known about how flowering time genes affect plant architecture. We grew four rice lines having different flowering time genotypes (hd1 ehd1, hd1 Ehd1, Hd1 ehd1 and Hd1 Ehd1) under distinct photoperiod conditions. By using genotype-treatment combinations that resulted in similar flowering times, we were able to compare the ef...

Rice is one of mankind's major food staples, and the erect panicle architecture in rice is an important morphological improvement. The dense and erect panicle 1 (DEP1) locus corresponds with the formation of erect panicles and has been widely used in rice breeding. However, the genetic diversity of DEP1 remains narrow. In order to improve the genetic diversity of DEP1, we used a rice germplasm ...

Panicle development, a key event in rice (Oryza sativa) reproduction and a critical determinant of grain yield, forms a branched structure containing multiple spikelets. Genetic and environmental factors can perturb panicle development, causing panicles to degenerate and producing characteristic whitish, small spikelets with severely reduced fertility and yield; however, little is known about t...

Grain-filling is a crucial process that determines final grain yield in rice (Oryza sativa L.). To understand the genetic basis of dynamics of grain-filling, quantitative trait locus (QTL) analysis was conducted using time-related phenotypic data on grain-filling collected from a population of 155 recombinant inbred lines (F12), derived from a cross between Milyang 23 and Akihikari. Two QTLs de...

Genetic analysis and inheritance patterns studies on agronomic yield characters were required to develop a plant breeding program. This study aimed obtain information performance, gene action, genetic diversity, heritability in the F2 population derived from crosses of local high-yielding varieties. The was conducted August-November 2021 Dramaga, Bogor. sorghum population, female male parents, ...
