Inflorescence development in cereals, including such important crops as rice, maize, and wheat, directly affects grain number and size and is a key determinant of yield. Cytokinin regulates meristem size and activity and, as a result, has profound effects on inflorescence development and architecture. To clarify the role of cytokinin action in inflorescence development, we used the NanoString n...

The intensity of trait association and genetic variability yield attributing variables in 217 rice genotypes was investigated during kharif 2018. existence among the demonstrated by analysis variance, which recorded significant differences for all seven studied parameters. estimation indicated that full grain number per panicle (37.2 % 34.1 %) & single plant (24.7 20.55 had highest phenotyp...

Inflorescence architecture is a key agronomical factor determining grain yield, and thus has been a major target of cereal crop domestication. Transition from a spread panicle typical of ancestral wild rice (Oryza rufipogon Griff.) to the compact panicle of present cultivars (O. sativa L.) was a crucial event in rice domestication. Here we show that the spread panicle architecture of wild rice ...

An experiment was conducted with the objective of evaluating panicle architecture traits different genotypes rice in relation to yield during June November 2020. The randomized complete block design three replications and forty-two treatments. graphical user interface used image analysis tool Panicle Trait Phenotyping (PTRAP) record related traits. Among genotypes, highest found high yielding l...

The aim of this research was to identify the vegetative and generative characters G16 rice mutants due gamma-ray irradiation. experiment conducted in Saribaye Village, Lingsar District, West Lombok Regency. experimental design used an Augmented Design, using three comparison plants, namely line (parent), Inpago Unram 1 variety, IPB 3S variety. four mutant populations tested were doses 200, 300,...

An experiment was conducted with a view to obtain information of genetic parameters variation and character association for 13 quantitative traits in set 64 rice cultivars Assam. The study revealed significant differences all the under study. Highest genotypic coefficient observed trait biological yield followed by harvest index grain yield. More than 80% heritability except yield, effective ti...

This study aimed to investigate the correlations among yield and component traits estimate direct indirect effects of these on grain in rice. The experiment was conducted during kharif 2022. Correlation coefficients path were analyzed determine relationships between seed yield. results showed significant positive such as effective tillers per plant, total number filled grains, spikelet fertilit...

A field experiment was conducted with a view to examining the effect of number seedlings hill-1 and spacing planting on growth yield transplanted aman rice (var. Ranisalute). The consisted five different viz. 2, 3, 4, 5 6 three plant 50 cm × cm, 40 30 cm. laid out in factorial randomized complete block design replications. Individually had no significant components. Numerically highest grain ha...
