Analysis of grain density and yield characters in aromatic rice genotypes Agrociencia
Shahidullah,S. M.; Hanafi,M. M.; Ashrafuzzaman,M.; Uddin,M. K.; Razi-Ismail,M..
Aromatic rices (Oryza sativa L.) normally produce enormous spikelets of low grain weight resulting low yield. Grain weight and grain density are the vital indicators of grain filling and mainly dependent on genetic make-up. Detail study of grain density and yield components of aromatic rice is a crucial need for yield improvement. An experiment was conducted with 40 rice genotypes to assess the grain density of aromatic rices and to observe the relationships of different grain categories with yield characters. The percentage of high density grains, good grains, average grains, poor grains, partially filled grains, spikelet sterility, and thousand grain weight were found to vary in a great extent. Maximum 50 % high density grain was harvested in BR39 and a...

Biomass production and grain yield of three sorghum lines difering in drought resistance Phyton
Castro-Nava,S; Ortiz-Cereceres,J; Mendoza-Castillo,M del C; Huerta,AJ.
The aim of this study was to determine the eficiency of drought classification criteria that we previously reported for our grain sorghum genotypes. Two tolerant genotypes of grain sorghum [Sorghum bicolor (L.) Moench] (UAT-124 and UAT-152) and one susceptible (UAT-30) were subjected to drought under greenhouse conditions at either panicle initiation, flag leaf, or flowering. Results showed that the effects of drought depended on when drought stress occurred during development. Biomass of the three sorghum genotypes was significantly reduced at the flag leaf stage (48%) by drought stress, but the greatest reduction occurred in the susceptible genotype UAT-30 (71%). Results showed that biomass accumulation for UAT-124 and UAT-30 was...

Aguiar,Aurélio Mendes; Carlini-Garcia,Luciana Aparecida; Silva,Adelmo Resende da; Santos,Mateus Figueiredo; Garcia,Antonio Augusto Franco; Souza Jr.,Cláudio Lopes de.
The utilization of diallel crosses for identification of superior combinations is a common practice in maize (Zea mays L.) breeding programs. This methodology allows the estimation of the combining ability of genotypes being evaluated. In this work, five inbred lines were evaluated as to their general (GCA) and specific (SCA) combining abilities, by using a complete diallel scheme. The single-crosses produced between these inbred lines were evaluated in seven environments, along with two checks, by using a randomized complete block design. Traits analized were: grain yield, plant height, ear height, ear placement, and prolificacy. A diallel analysis was carried out, following an adaptation of Griffing's method IV, in addition to hybrid stability and...
