Response of transgenic Bt cowpea lines and their hybrids under field conditions

Transgenic cowpeas are those genetically engineered with Cry1Ab gene for protection against the lepidopteran pest Maruca vitrata that could inflict upto 80% yield loss in severe infestation. Two transgenic events TCL-709 and TCL-711 were crossed to three non-transgenic lines IT97K-499-35, IT93K-693-2 and IT86D-1010 to generate six set of F1 hybrids. The study was designed and conducted to evaluate the performance of...

Analysis on combing ability and estimation of genetic parameters for chlorophyll content in maize

Chlorophyll closely related to photosynthetic capacity and developmental stage in crops. In order to reveal the genetic characters of chlorophyll content in leaf above ear, ear leaf and leaf under ear (three-ear-leaves) of maize, ten inbred lines from five different heterotic groups were selected to make crosses by a completely diallel cross design. The combining ability analysis and genetic parameters estimations of...
