    摘要:

    以国家果树种质寒地果树圃(公主岭)保存的黑穗醋栗资源为研究对象,计算分析22个表型性状多样性指数、标准差、变异度和极值,分析资源表型多样性,并以百果重、可溶性固形物、风味为指标,结合口尝鼻嗅评价,筛选适宜鲜食资源。结果表明,供试资源非数值型性状的Simpson指数和Shannon-weaver指数变化范围为0.13-0.74和0.46-2.10,数值型性状Simpson指数和Shannon-weaver指数变化范围为0.06-0.88和0.20-3.04,在供试资源的22个性状中,共有10个性状:初花期、花序着生状态、果皮厚度、果肉颜色、果实风味、果实质地、百果重、可溶性固形物、花序长度、每花序花数,多样性指数较高,表明现保存的黑穗醋栗资源表型多样性较为丰富,基本满足晚花、适宜果实鲜食与加工特性和(或)产量形成对表型多样性需求;果实整齐度、果实硬度多样性较差,因此需要加强相关资源收集评价研究。综合分析果实大小、风味、可溶性固形物等性状以及口尝鼻嗅评价分数,评价筛选出五份资源:11C-18(实生后代)、C82、11C-22(实生后代)、大粒甜、布劳德较适宜鲜食,可为进一步鲜食资源评价选育提供参考资源。

    Abstract:

    The phenotypic diversity of Black Currant germplasm resources conserved in National Field Genebank for Hardy Fruits (Gongzhuling) China (NFGHF) was analyzed by calculating and analyzing the diversity indices, standard deviations, variances and extreme values of 22 phenotypic traits. Combining with tasting and sniffing, we screened resources suitable for fresh-eating through using fresh-eating fruit evaluation index, weight per 100 berries, soluble solids and flavor of berries . The results showed that Simpson index and Shannon-weaver index of non-numerical traits varied from 0.13 to 0.74 and 0.46 to 2.10. Simpson index and Shannon-weaver index of numerical traits ranged from 0.06 to 0.88 and 0.20 to 3.04. Among the 22 traits of tested resources, diversity indexes of ten traits were higher, including date of first blooming, state of inflorescence, thickness of seedcase, flesh color, berry flavor, flesh texture, weight per hundred berries, soluble solid content of berries, inflorescence length, flower number per one inflorescence. The results indicated that the phenotypic diversity of the black currant resources conserved in NFGHF was more abundant which could meet basically the germplasm resources for the late flowering, fruit property suitable for fresh-eating, processing characteristics and (or) yield formation. The diversities of fruit uniformity and fruit hardness were poor, so we should work hard for the collection and evaluation of the relevant poor diversity resources. Comprehensive analysis of the fruit size, flavor, soluble solids and other properties, as well as tasting and sniffing fruit, we screened out five accession resources suitable for fresh-eating , including 11C-18 (seadling offspring), C82, 11C-22 (seadling offspring), 92/69A, Brodrop, which can provide reference resources for further the evaluation and screening of Black Currant suitable for fresh-eating.
