It has been speculated that the rapid tuberization of explanted etiolated stolon nodes of the common potato relates to the osmotic concentration of the medium since this response is speeded by increased sucrose levels up to 12%. This paper demonstrates that the response probably pertains to the energy requirements of the tuberizing explanted stolon and that osmotic concentration is not crucial.

ABSTRACT The genetic control of eight isozyme loci revealed by starch gel electrophoresis was studied through the analysis of three progenies derived from four tetraploid cultivars of Solanum tuberosum (groups Andigena and Tuberosum). Duplicate gene expression was found in seven (Got-A, Got-B, Pgd-C, Pgi-B, Pgm-A, Pgm-B and Pox-C) isozyme loci. In another isozyme gene (Adh-A), the parental genotypes were not adequate to distinguish between a monogenic or a digenic model of genetic control. Tetrasomic inheritance was demonstrated in four (Got-A, Got-B, Pgd-C and Pgi-B) isozyme loci. In the remaining duplicate genes, the parental genotypes precluded discrimination between disomic or tetrasomic models. Tetrasomic segregations of the chromosomal type were generally found; however, the isozyme phenotypes shown by three descendants from selfing cv. Katahdin indicate the occurrence of chromatid segregations, although aneuploidy cannot be ruled out. Either autoploidy or amphidiploidy with lack of chromosome differentiation between the two diploid ancestors can account for the existence of tetrasomic inheritance in the common potato.

Potato Plantlets

In vitro plantlets of four varieties of potato (Solanum tuberosum L.) were grown at different plant densities to study their effects on growth and microtuber yield. The responses of the cultivars to plant density, as expressed by changes in development characteristics, especially stem length and leaf area, were different. The time of tuber initiation was earlier at higher plantlet densities for all cultivars. The microtuber number per plantlet was not affected by the plantlet density. The highest number of well-sized (≯4 mm) microtubers per jar could be harvested from the higher plantlet densities (30–40 plantlets per jar). In addition to good yield, the microtubers were uniform in these treatments, so they appear to be economical.

To determine the influence of gibberellic acid (GA3) and 6-furfuryl aminopurine (kinetin) concentrations alone and in combinations on in vitro tuberization of potato, nine treatments consisting of combinations of gibberellic acid and kinetin at three levels of concentration (0, 2, and 5 mg·liter–1) were included in Murashige and Skoog medium supplemented with 6% sucrose. Four single nodes of in vitro plantlets from Solanum tuberosum L. cultivar Atlantic were placed into each magenta box. All magenta boxes were arranged in a randomized complete box design with five replications and cultured under a short photoperiod condition (8 h light/16 h dark). Gibberellic acid strongly inhibited tuberization when used alone or with kinetin, whereas kinetin induced tuberization at both 2 and 5 mg·liter–1. Although tuberization was initiated in the absence of kinetin because of the high concentration of sucrose and short photoperiod, the presence of kinetin accelerated the in vitro tuberization process of potato.

Large Size

Five protocols of micro tuberization were used to induce large size microtuber in three recommended potato varieties, namely Cardinal, Diamant, and Heera under complete dark condition. Tuberization was the earliest (11.8 days) in the protocol P2 (MS + 5 mg/l BAP + 500 mg/l CCC + 8% sucrose), which was closely followed by that in P1 (12.7 days) (MS + 5 mg/l BAP + 50 mg/l coumarin + 8% sucrose). Maximum number of microtubers/flask (12.8) was obtained from the protocol P1 followed by that of P2 (11.6) that contained growth retardant; but higher average weight of microtuber was obtained in the protocols P5 (30 days old plantlet + MS media containing 40 meq K + 10 mg/l BA + 9% sucrose), P4 (MS + 10 mg/l BA + 8% sucrose), and P3 (MS + 5.0 mg/l BAP + 6% sucrose) which contained BA in absence of growth retardant. The average weight of microtuber was the highest (329.0 mg) in protocol P5, followed by that in P4 (280.7 mg), while it was the lowest in protocol P1. The variety Diamant produced maximum average weight of microtuber (246.3 mg), while Heera produced minimum (226.1 mg), which was statistically similar to Cardinal (228.7 mg). The highest percentage (52.2) of >300 mg size and lowest percentage (19.3) of <150 mg size microtuber was produced in P5 protocol in the variety Diamant. On overall consideration, all the varieties performed best with the protocol P5. DOI: http://dx.doi.org/10.3329/bjar.v39i1.20143 Bangladesh J. Agril. Res. 39(1): 59-66, March 2014
