论“株系循环法”

“株系循环法”及其变型，是于不同授粉方式的农作物原种生产新技术。它的主要特点是建立保圃，逐步消除育种剩余变异，将“三圃制”中的株行圃和株系圃融为一体。应用众数选择对保种圃进行连续鉴定，并在开放授粉条件下混合繁殖。

Discussion on 'Plant-line Cycle Method'

'Plant-line cycle method' and its transformations ('selfing and mixed propagation methodl and 'inbreeding and mixed propaga-tion method' ) are new techniques used for crops foundation seeds production of different pollination style. Its characteristics are to establish the seed maintained plot, eliminate the remaining variation of breeding progressively, and combine the plant -row polt and the lant-line plot of 'three-plot system'. The seed-mainatined plot is appraised continuously by the mode selection, and propagated mixedly under the open-pollination condition. The practice has proved that 'plant-line cycle method' has the advantage of greater,faster, better and more economical results, and constitutes the new technical system of crops seeds production.
