Potato (Solanum spp.) in an isohyperthermic environment III. Evaluation of clones

Influence of production and storage conditions on subsequent growth and tuber yield of potato (Solanum spp.) in the hot tropics

“…Less dependence on an imported supply of planting material should be one of the prime objectives. Our data suggest that, for an annual production cycle of the type envisaged for the lowland tropics (Vander Zaag & Demagante 1988), tuber yields will invariably be below the potential obtainable with highland seed tubers unless CS is available. Economics may dictate lower yields as an acceptable alternative to imported seed tubers from the highlands or from temperate countries.…”

“…Vander Zaag & Demagante (1988) evaluated clonal performance using a similar annual CS system. They identified B-71-240-2 and Desiree as clones with potential for the lowland tropics.…”

“…The clone B-71-240-2 is mediumlate in maturity and was selected in Argentina from a cross involving S. tuberosum ssp. tuberosum and S. stoloniferum; it has gained widespread popularity in both warm and cool climates (Vander Zaag & Demagante 1988). Clone 278072-10 was chosen for this study because of its late maturity and as a representative of a cross between 5. tuberosum ssp.…”

Effect of production environments on radiation interception and radiation use efficiency of potato(Solanum tuberosum)grown in Canterbury, New Zealand

“…Therefore, RI and RUE have been used to investigate the interaction between potato cultivar and production environments, and to explain genotypic differences in potato (Solanum tuberosum) crops in diverse climates (Simba 1970;Allen & Scott 1980;Van der Zaag & Doornbos 1987;Van der Zaag & Demagante 1988;Trebejo & Midmore 1990). There have been similar studies on other crops such as sugarbeet (Monteith 1977), barley (Gallagher & Biscoe 1978), field beans (Hussain et al 1988), and lentil (McKenzie & Hill 1991) in which differences in yield were related to RI and RUE.…”
