Specific Influence

For tuber-bearing Solanum species, six monogenic recessive synaptic mutants, designated sy-1, sy-2, sy-3, sy-4, ds, and dsc have been reported in the literature. In the present investigation no indication for the existence of the mutant sy-1, affecting megasporogenesis only, was found. The mutant ds was confirmed to display typical desynaptic behaviour in microsporogenesis and shown to similarly affect megasporogenesis. It furthermore proved to be allelic to the mutants sy-3 and dsc. It is proposed that the mutants sy-3, ds, and dsc be uniformly designated ds-1, whereas the remaining mutants sy-2 and sy-4 (possibly identical) may be designated simply as synaptic mutant until their actual identity has been established. The observed F1 segregations generally support monogenic recessive inheritance of ds-1. However, in one cross progeny the expected mutant phenotype was not clearly expressed in contrast with its reciprocal, which might indicate cross-specific influence of the cytoplasm on ds-1 expression. The potential value and limitations of desynaptic (ds-1ds-1) mutants for potato breeding and true potato seed production are discussed.Key words: Solanum, (de)synaptic mutants, microsporogenesis, megasporogenesis, 2n gametes.

Glyphosate Drift

Field trials were conducted to evaluate the effect of simulated glyphosate drift rates applied to two non-irrigated potato cultivars in the late tuber bulking stage grown for potato seed production. Mother plants receiving a sublethal glyphosate application had similar yields regardless of the year or cultivar. ‘Red LaSoda' seed pieces visually evaluated the following spring had more sprout inhibition from glyphosate-treated plots. With ‘Russet Burbank', only seed pieces from mother plants that received more than 18 g ha−1 glyphosate showed sprout inhibition. Total yield reductions the year following glyphosate treatments were attributed to fewer and smaller tubers from plants that did not emerge or were delayed in emergence. Red LaSoda seed pieces from mother plants receiving ≥ 71 g ha−1 glyphosate yielded less than the nontreated. In 2005, Russet Burbank seed pieces from mother plants receiving ≥35 g ha−1 glyphosate had reduced yields, whereas in 2006, all glyphosate treatments reduced total yield compared with the nontreated.

Plot Design

Experiments were conducted to show the effect of split application of nitrogen (SN) and boron (B) on hybrid True Potato Seed (TPS) production. The TPS-67 (♂) and MF-II (♀) were used as crossing materials. The experiments comprised two factors i.e., factor-A; nitrogen splitting (4 levels): 2 split (SN0-Conventional), 3 split (SN1), 4 split (SN2) and 5 split (SN3) where 50 kg N ha–1 applied as basal from total 300 kg N ha–1 with each split application and the rest 250 kg N ha–1 was splitted as per treatment at 10 days intervals started from 30 DAP (days after planting); and factor- B; boron (4 levels): 0 (B0), 4 (B1), 6 (B2) and 8 (B3) kg B ha–1 under split-plot design with three replications. We found that SN and/or B influenced the hybrid TPS production. The maximum yield (2160.1 mg) of TPS plant–1 was found from SN1B3 and the minimum (1001.8 mg) was in SN0B0. The maximum yield (172.81 kg) of TPS ha–1 was found from SN1B3 and the minimum (80.14 kg) was in SN0B0. The maximum weight (86.87 mg) of 100-TPS was found from SN3B3; whereas, the minimum (53.36 mg) was in SN0B0.
