Estimation of Genetic Variance Components Sunflower Fatty Acids Under Normal irrigation and Drought Stress Conditions Using Line × Tester Method

determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 2003) and at two locations in Khartoum S...

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 genotyp...
