An estimation of the combining ability of barley genotypes and heterosis for some quantitative traits
ABSTRACT- Barley (Hordeumvulgare L.) is one of the most important cereals in the world which is used as human and cattle feed and for malt production. One of the most important steps in a hybrid and selection breeding program of barley is the selection of suitable parents with high general (GCA) and specific combining ability (SCA) for grain yield. In order to estimate the combining ability and...
متن کاملestimation of heritability and heterosis of some agronomic traits and combining ability of rice lines using line × tester method
in order to determine combining ability, heritability and heterosis of some agronomic traits in rice, 4 pure lines were crossed with 2 cytoplasmic male sterile testers. parents and their f1 progenies arranged in rcb design with three replications. analysis of variance showed significant differences among genotypes for all traits, except for filled grains/panicle. furthermore, the crosses effect...
متن کاملHeterosis, combining ability and drought susceptibility index in some crosses of bread wheat (Triticumaestivum L.) under water stress conditions
Eight bread wheat genotypesof diverse origin were crossed in a half-diallel model in 2011/2012 season. The eight parents (Sahel-1 P1, Giza-168 P2, Misr-1 P3, Gemmieza-9 P4, Gemmieza-11 P5, Line-1 P6, Line-2 P7, Line-3 P8) and their 28 F1 hybrids were evaluated under normal and water stress conditions during 2012/2013 season in a two field experiments wereas designed a randomized complete block ...
متن کاملestimate of heterosis and combining ability in ranian melon using diallel crosses analysis
in order to estimate heritability, heterosis, general and specific combining ability and relationships between them in traits of fruit number per plant, days to the first fruit harvest, yield per plant, average fruit weight and rind thickness, seven local populations of iranian melon (‘tashkandi’, ‘khatouni’, ‘garmak’, ‘aran1’, ‘mirpanji’, ‘suski-e-sabz’ and ‘golpaygan’) were crossed using a co...
متن کاملEstimation of Combining Ability and Gene Effects in Forage Maize (Zea mays L.) Using Line × Tester Crosses
Abstract Determination of gene effects and combining abilities is a critical stage in maize hybrid breeding. In the present study, 20 S6 lines as female and three S6 inbred lines (K18, K19 and K1264/5-1) as tester were crossed and the resulting test cross progenies were evaluated in a randomized complete block design with three replications in 2008. During the growing period, several agronomi...
