As triploids produce seedless fruits the best production is investigated. Comparative studies of embryogenesis, seed set, size, and germination were carried out following 4x x 2x and 4x x 4x crosses. On the average, both crosses yielded similar numbers and proportions of fully developed seeds per fr

The relative breeding value of first division restitution (FDR) and second division restitution (SDR) 2n male gametes from diploids, and n (2x) gametes from tetraploids were compared. This was done by measuring tuber yield of 105 4x families obtained from 4x x 2x (FDR), 4x x 2x (SDR), and 4x x 4x cr
The occurrence of 2n pollen-producing plants was investigated in 187 plant introductions (PIs) of 38 wild species of tuber-bearing Solanum. These 2x, 4x, and 6x species are from Mexico, and Central and South America. The determination of 2n pollen-producing plants was conducted using acetocarmine gl
The objectives of this research were to evaluate the response to day length and the yield stability of environments of 4x families from 4x x 2x crosses in potato. Twenty families from crosses between 4x female parents with different genetic backgrounds and 2x parents, which formed 2n pollen by first
