In rice panicle development, new meristems are generated sequentially in an organized manner and acquire their identity in a time- and position-dependent manner. In the panicle of the panicle phytomer2-1 (pap2-1) mutant, the pattern of meristem initiation is disorganized and newly formed meristems show reduced competency to become spikelet meristems, resulting in the transformation of early ari...

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...

A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...

seven rice varieties (hassani, deilmani, sepidrod, shahpasand, saleh, neda, and irfaon215) along with their complete diallel progenies were grown in a randomized complete block design of three replications in the growing seasons of 2006 and 2007 and were evaluated for the quantitative traits of: number of days to flowering, flag leaf length, width and area, plant height, panicle length, extrusi...

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Grain yield was greatly increased during the genetic improvement of japonica inbred rice since 1980s in Jiangsu, east China; thus, an improved plant morphology should be expected, considering that is a decisive factor determining grain yield. Twelve representative released from 1983 to 2013 were grown same fields 2019 and 2020. (p &lt; 0.01) at 63.3 kg ha−1 year−1 across 2 years among cultivars...

a study was conducted on genetics of some important agronomic traits (number of productive tillers per hill, plant height (cm), panicle length (cm), number of spikelets per panicle and 100-grain weight) in rice during 2012-13. two lines were crossed with five testers in line × tester fashion to produce 10 f1 hybrids. analysis of variance revealed significant differences among genotypes and cros...

The panicle architecture is a critical determinant of the reproductive success rice plants and has direct impact on grain production. In this study, we evaluated genetic variation parameters in fifteen genotypes compared them with five commonly grown cultivars study area to assess their potential for crop improvement initiatives. selection 15 was based specific criteria, including diversity ori...
