Selection method for flat round eggplant selfing line

Abstract

The invention relates to a selection method for a flat round eggplant selfing line. The selection method comprises the following steps: (1) hybridizing Dali Qieza #6 of a flat round eggplant, which serves as a female parent, and Zilong #7 of an elongated eggplant, which serves as a male parent, thus obtaining hybrid seeds; (2) after the hybrid seeds are planted, performing back-crossing on Dali Qieza #6 serving as a male parent, thus obtaining back-crossed seeds; (3) after the back-crossed seeds are planted, selfing single plants, selecting the seeds of the flat round eggplants, continuously performing single plant selfing after planting, and selecting the seeds of the flat round eggplants again; (4) planting the seeds of the flat round eggplants, and continuously selfing high-quality single plants according to stress resistance and quality character for 4 to 5 generations to obtain a stable flat round eggplant selfing line Yj-01. The selection method ensures that the prepared hybrid seeds have the characteristics of high quality, high stress resistance, high applicability and good commercial quality.
