Breeding and Application of a New Cyperus esculentus L. Cultivar Jisha 15

摘要:

吉莎15(认定编号：吉认油莎2025004)是吉林省农业科学院通过对非洲马里油莎豆种质资源30GD2进行⁶⁰Co-γ辐照(微剂量3~5 Gy/min)，经系谱法选育而成的油莎豆广适新品种。吉莎15植株生长旺盛，具有高产、抗旱、抗逆性强等特点。本文系统阐述该品种的选育过程、特征特性、产量表现及配套栽培技术，以期为该品种的推广应用提供科学依据。

Abstract:

‘Jisha 15’(Official recognition No. Jirenyousha 2025004) is a new, widely adapted tigernut(Cyperus esculentus L.) cultivar developed by the Jilin Academy of Agricultural Sciences. It was derived from tigernut germplasm accession 30GD2 introduced from Mali through ⁶⁰Co γ-ray irradiation at a low dose rate of 3- 5 Gy/min, followed by successive pedigree selection.‘Jisha 15’exhibits vigorous growth, high yield, drought tolerance and strong tolerance to other environmental stresses. This paper systematically describes its breeding process, agronomic and biological characteristics, yield performance and recommended cultivation practices, thereby providing a scientific basis for the extension and application of this cultivar.
