Journal Article 1994

Autor: Watanabe, K. Orillo, M. Iwanaga, Masaru Ortiz, R. Freyre, R. Perez, S.

Diploid cultivated species, haploids derived from tetraploid cultivars, and their wildSolanum relatives were used to generate various diploid potato genetic stocks. These stocks have significant value in potato breeding because: 1) genetic diversity in the potato population can be kept variable w...

Accelerated soil-nitrifier activity and rapid nitrification are the cause of declining nitrogen-use efficiency (NUE) and enhanced nitrous oxide (N2O) emissions from farming. Biological nitrification inhibition (BNI) is the ability of certain plant roots to suppress soil-nitrifier activity through...

Hybridization of synthetic allotetraploids of S. pinnatisectum with S. etuberosum (4x-EP) with S. acaule (2n = 4x = 48) resulted in two individuals that were highly fertile, in contrast to all other progenies. The unique individuals are hexaploids, 2n = 72, while the other progenies are tetraploi...

The use of ploidy manipulations in potato breeding has been successfully applied by breeders at the International Potato Center (CIP) as a tool for germplasm enhancement and for the introduction of desirable genes of wild species into the cultivated gene pool. This methodology consists in reducin...

The responsibility of CIAT`s Genetic Resources Unit in the preservation of germplasm of beans (Phaseolus), cassava and its wild relatives (Manihot), and tropical forages (legumes and/or grasses) is pointed out. The main characteristics of the collections are indicated. Distribution, improvement a...
