Recent progress in cassava varietal improvement in the Philippines
1995
Mariscal, A.M. | Bacusmo, J.L.
The report covers varietal improvement for the period 1990-1993. Not much progress was made in the 1990/91 season due to the occurrence of a super typhoon that damaged standing field trials. In recent years, however, progress in selection was made in terms of high yield and dry matter content and good plant type. The cassava germplasm bank of PRCRTC has currently a total of 270 accessions, including 30 varieties introduced through tissue culture from Thailand. From this germplasm a polycross nursery and hybridization block were established to incorporate desirable genes into the local cultivars. Since 1991 about 3659 new genotypes have been evaluated by PRCRTC. From these evaluations and screenings two varieties of CIAT origin were released by the Philippines Seedboard.
