Effectiveness of Selection at Transplant and Minituber Crop Level in Potato (Solanum tuberosum L.)

Abstract

ABSTRACT

The existence of genetic associations between important potato traits indicates that selection practiced for one trait may lead to changes in another. Correlations were computed between normal crops and transplant and minituber crops in order to study the selection efficiency for agronomic characters in potato transplant and minituber level. Three different transplant (field, glasshouse, seed bed) and two minituber (3g, 13g) crops were produced in glasshouse and field conditions. Selection at glasshouse transplant level was found to be moderately effective for average tuber weight, node number and leaf length, and moderately to highly effective for plant height, stem number, leaf number, leaflet length, leaflet width, tuber number and tuber yield in minituber level. Selection in transplant and minituber level for some agronomic characters in potato would be effective under certain conditions.
