“…Staminate plants produce more spears than do pistillate plants which bear berries with seeds (Robbins et al, 1925;Yeager et al, 1938). Among seed-propagated cultivar of 'Mary Washington 500W' (MW500W), large differences are observed in sprouting and flowering times, stem and spear types, and stem and scaly-leaf colors, etc.…”

“…Male plants showed productive characteristics at early spring sprouting (Robbins and Jones, 1925), uniform spear diameters (Ellison et al, 1960), increased numbers of spears (Robbins and Jones, 1926), and higher total spear weights (Robbins and Jones, 1926;Sinton and Wilson, 1999), while female plants had higher weight per spear (Franken, 1970;Robbins and Jones, 1925) in open field culture.…”

This study analyzes the first large-scale asparagus experiment in Japan to examine the productive differences between male and female plants using the rootstock-planting forcing culture technique. This technique has recently been developed in Japan and uses dug-up rootstocks for one-season harvests during the off-crop season. As larger spears and early sprouting are especially favored in this culture for higher yield, it is important to clarify and evaluate the productive traits of the male and female plants. We conducted collaborative research among eight institutes from Hokkaido to Kyushu to examine plants grown at different cultivation sites. There were two digging-up months and different low-temperature backgrounds. Plant rootstocks sourced from the eight different sites used in the experiment were cultured in an abandoned tunnel in Nagano Prefecture, Japan, in a large area with uniform temperature and high humidity throughout the year, and their white spears were harvested. The results of this study show that the female plants had a significantly higher rootstock weight, weight per spear per plant, and weight per early spear per plant, whereas the male plants had a significantly higher total spear number per plant, early spear number per plant, and significantly fewer days to first harvest. No significant differences were observed in soluble solid contents of roots, total spear weight per plant, or early spear weight per plant. It seems that male plants have a tendency to sprout earlier than female plants in response to reduced accumulated low temperature hours, and also to produce a higher total spear number per rootstock weight and total spear weight per rootstock weight. The ranges of most of the productive traits analyzed in this study completely overlapped between the sexes. However, female plants showed higher variation in weight per spear per plant and weight per early spear per plant.

“…Survival of male plants also was significantly higher than females. Higher yield from and greater longevity of male plants is reported frequently in the literature (Handy 1897;Tiedjens 1924;Robbins & Jones 1925;Yeager & Scott 1938;Sneep 1953;Ellison & Schermerhorn 1958;Ellison et al 1960;Bannerot et al 1969;Moon 1976) and may be associated with higher disease tolerance in male plants (Franken 1970;Falloon 1982;ElIison 1986), the utilisation of storage carbohydrates in females for berry production at the expense of spear bud formation (Malhotra 1930;Robb 1984), or greater drought tolerance of male plants (Si vtsev & Sizov 1971).

Asparagus: value of individual plant yield and fern characteristics as selection criteria

The yield of individual plants in a population of Asparagus officinalis L. cv. 'Mary Washington 500W' was recorded for the first four and the 9th and 10th harvest seasons. The yield of both male and female plants declined between the two periods. Average yield of males was higher than that of females in all seasons. Therefore, selection of the highest yielding male plants to establish fields of cloned plants may result in higher yields than if the highest yielding female plants were selected. There were significant positive correlations (a) belween both market and total yields averaged over the 2nd-4th seasons and market yield averaged over the 9th and 10th seasons for males, and (b) between total yield of females averaged over the 2nd-4th seasons and market yield averaged over the 9th and 10th seasons. No significant correlations were found between fern vigour ratings, number of fern stalks per plant, or average early market yield in the 2nd, 3rd, and 4th seasons and mean market yield over the 9th and 10th seasons: hence, these characters cannot be used to identify plants that will remain highly productive for 9 or 10 harvest seasons. Conversely, the use of these criteria to select plants in old asparagus fields may not necessarily result in accurate identification of plants that are highly productive in the first four or five years after eSlablishment.
