Abstract
Abstract The relationship between seed quality characters and field emergence of garden pea seed lots was evaluated in 1988 for 82 seed lots from six cultivars under unirrigated conditions, and in 1989 for 23 seed lots from three cultivars under both irrigated and unirrigated conditions on several sowing dates. This study constitutes the most extensive evaluation of the prediction of field emergence in garden peas yet conducted. The favourable 1988 sowing conditions allowed good field emergence. However, low rainfall in November 1989 (unirrigated sowings) and excessive water at the 30 October and 20 December 1989 (irrigated sowings), were associated with reductions in field emergence. The germination test was correlated with field emergence when conditions for sowing were favourable and when low germinating seed lots were included in the analysis. However, when low germinating seed lots (<85%) were excluded, the relationship between germination and field emergence was low and unreliable. Differences in fi...
