This study was conducted to determine the combining ability and heritability of rice grain quality traits. Some grain quality traits such as grain length, grain width, milled grain length, milled grain width, length to width ratio, milled rice recovery, head rice recovery, amylose and gel consistency were analyzed using a full diallel mating design in Malaysian rice varieties. This study was co...

Common beans are an important nutritious food crop to many people in developing countries. Inadequate soil-P is one of the major constraints high bean seed yield productivity. Information about genetic effects that control inheritance root traits common grown under low conditions scarce, and a challenge for enhancement. This study was therefore implemented determine gene action tolerance soil-P...

Characterization and conservation of germplasm is a critical step toward the genetic improvement crop. This study assessed variation in 257 common bean genotypes which included 207 accessions obtained National Gene Bank Kenya, 33 from Kenya Agricultural Livestock Research Organization (KALRO), 13 landraces collected farmers’ fields four commercial varieties for various agronomic traits. T...

The consumption of products made from Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn.) has increased in recent years in Japan. Increased consumer demand has led to recognition of the need for early varieties of this crop with high and stable yields. In order to accomplish this, more information is needed on the genetic mechanisms affecting earliness and yield. We conducted genetic analysis ...

Genetic variation for thermal plasticity plays an important role in the success or failure of a species with respect to the colonization of different thermal habitats and the ability to deal with climatic change. The aim of this paper is to study the relative contribution of the additive and non-additive components of genetic variation for the slope of the temperature reaction norm for juvenile...

seven maize inbred lines were crossed in a complete diallel cross design at the seed and plant improvement institute, karaj, iran, during the 2006 growing season. the parents and 42 f1 hybrids were grown in the research field of islamic azad university of firoozabad, firoozabad, iran, using a randomized complete block design (rcbd) with three replications, during the 2007 growing season. the ha...

in order to study the mode of genetic control and heritability of morphological characteristics important for the improvement of root weight, sugar yield and white sugar yield in tropical beet, griffing's diallel cross method along with the biplot display of diallel data were applied. nine sugar beet lines including 7112-36, 7173, 474, 452, 261, 436-104, sb-firoz, rr607 and 436 were crosse...
