An experiment was conducted using a randomized complete block design to estimate genetic variability of ten rice genotypes. Analysis of variance for yield and yield contributing traits showed significant (p<0.01) variation among the genotypes. Results of genetic analyses showed a higher phenotypic coefficient of variation compared to their corresponding genotypic coefficient of variation for al...

Sixty four parental lines of hybrid rice were evaluated for genetic divergence by taking into account nine traits during two seasons year 2018. By resolving the ten groups, Ward's clustering method demonstrated having significant diversity. Cluster X had most (13) out all clusters, followed cluster II (12 genotypes). The line clusters IX, VIII, VII, V, and IV, which correspond to SD-5, SD-2, HS...

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, ...

Five populations segregated in isogenic backgrounds and three sets of near isogenic lines (NILs) overlapping in a 362.3-kb region covering heading date gene Hd1 were developed from the indica rice cross Zhenshan97 (ZS97)/Milyang 46 (MY46). They were used to analyze the effects of Hd1 on heading date, plant height and yield traits. In a background of the parental mixtures, the photoperiod-sensit...

Improved root architecture is an effective strategy to increase crop yield. We demonstrate that overexpression of transcription factor gene MORE ROOT (TaMOR) from wheat (Triticum aestivum L.) results in more roots and higher grain yield in rice (Oryza sativa). TaMOR, encoding a plant-specific transcription factor belonging to the ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) protein fam...

The variability analysis showed the presence of highly significant variations for all listed genotypes tested under research experiment. Phenotypic coefficient variation traits investigation was found higher than their corresponding genotypic variation, indicating masking effect environment in expression traits. High heritability reported plant height (cm), days to 50% flowering, 1000 seed weig...

The present study was carried out in Agricultural Research Station, Hagari during rabi 2020, it undertaken to assess nature of genetic variability and diversity among 200 mutant lines M4 generation. revealed wide variation for yield attributing traits, moderate GCV PCV coupled with high heritability advance observed stem girth, panicle length width. traits viz., length, weight, width, 100-seed ...

The present experiment was carried out in twelve genotypes including IRRI introgression lines and a Japonica cultivar to analyse the genetic variability, heritability, gain. Significant differences were observed among genotypes. All traits under study recorded high phenotypic coefficient of variation (PCV) than genotypic (GCV) indicating presence environment controlling traits. But, less differ...

The development of new rice varieties is highly dependent on genetic diversity in desirable agronomic traits. Therefore, this study aimed to identify potential genotypes having the characters Korean (Tongil-type) and japonica developed through doubled haploid (DH) technology apply our breeding materials. 35 elite DH lines derived from another culture African along with two local checks were pla...
