general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

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...

in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...

for different agronomic traits in sunflower (helianthus annuus l.) inbred lines were estimated using “line × tester” analysis method. six new restorer lines were crossed with four cms lines as tester in 2006 growing season. the 24 f1 single cross combinations were planted in complete randomized block design with four replications in khoy field research station in 2007 growing season. there were...
