Genetic distance among doubled haploid maize lines and their testcross performance under drought stress and non-stress conditions
In contrast to conventional inbreeding that takes up to seven generations to develop inbred lines, the doubled haploid (DH) technology allows production of inbred lines in two generations. The objectives of the present ...
Testcross performance of doubled haploid maize lines derived from tropical adapted backcross populations
Doubled haploid (DH) lines produced by in vivo induction of maternal haploids are routinely used in maize breeding. The present study was carried out to assess the performance of 75 doubled haploid maize testcrosses and ...
