Estimation of genetic divergence among some cotton varieties by RAPD analysis

Total genomic DNA from 15 cotton varieties were analysed to evaluate genetic diversity among them through random amplified polymorphic DNA (RAPD) analysis, with 30 random decamer primers using the polymerase chain reaction (PCR). A total of 370 bands were observed, with 12.3 bands per primer, of which 91.6% were polymorphic. OPM-16 produced the maximum number of fragments while the minimum number of fragments was...

Evaluation of intra- and inter-specific rice varieties adapted to valley fringe conditions in Burkina Faso

  The immense potential of the lowlands in Burkina Faso for durable intensification of rice cropping have not been realised due to biotic and abiotic stress constraints.To this end, the rice research program in Burkina Faso evaluated 16 intra-and inter-specific lowland progenies in 2002 and 2003. The aim of the study is to introduce new lowland NERICAs through a participatory approach and to identify ideotypes...

Studies on effectiveness and efficiency of gamma rays, EMS and their combination in soybean [Glycine max (L.) Merrill.]

  Mutagenic effectiveness and efficiency of gamma rays, EMS and combined treatments was studied in terms of M2 (progenies) lethality and chlorophyll mutations in two cultivars of soybean (Pusa-16 and PK-1042). In general the frequencies of chlorophyll mutations were high in gamma rays and combined treatments. Four types of mutants viz., albina, xantha, chlorine and viridis were observed in the...
