摘要

目的：利用向日葵特异性简单序列重复（SSR）标记，对新开发的杂交种（TilhanTec-SUNH-1）以及 2 个雌性品系、4 个雄性品系和 3 个杂交种进行 DNA 分析，以开发出更多种子和油产量高、抗或耐主要病害（霜霉病）和虫害（叶蝉）的杂交种，用于雨养条件下的商业化种植。方法：利用两个亲本（ARM-243A 和 RGP-100）培育了一个新的向日葵杂交种 TilhanTec-SUNH-1（IIOSH-15-20）。通过全印度协调试验（IHT、AHT-I 和 II）和在三个地点进行的邦多地点试验，在三年的向日葵收获季节和蕾期，分别在 29 个和 14 个地点对入选品种的表现进行了评估。共记录了 9 项定量观测结果。对 4 个杂交种共使用了 80 个 SSR 引物进行 DNA 指纹识别。结果在 AICRP 试验中观察到，DRSH-1 和 KBSH-44 的种子产量分别比 DRSH-1 和 KBSH-44 高出 28.7% 和 10.5%。与国家对照 DRSH-1 和 KBSH-44 相比，出油率的优越性分别为 27.1%和 27.3%。TilhanTec-SUNH-1 对霜霉病和叶蝉的抗性（0%）为 1.1 级，对 Alternariaster 叶斑病的抗性为 0%。四个 SSR 标记，即 ORS-57、ORS-203、ORS-1028 和 ORS-598，可用于 TilhanTec-SUNH-1 的鉴定和基因纯度测试。解释：调查结果表明，TilhanTec-SUNH-1 在种子和油脂产量、抗霜霉病、中抗叶蝉和抗交替花叶病方面表现优异。TilhanTec-SUNH-1 已由印度向日葵研究中心（CVRC）公布，可在印度向日葵种植邦的雨水灌溉条件下进行商业化种植。关键词霜霉病杂交育种分子标记产油量种子产量

TilhanTec-SUNH-1 (IIOSH-15-20): A new high seed and oil yielding and downy mildew resistant sunflower hybrid suitable for rainfed condition of India

Aim: To develop more heterotic hybrids for seed and oil yield coupled with resistant or tolerant to major disease (downy mildew) and insect pests (leafhoppers) for commercial cultivation in rainfed conditions and DNA profiling of the newly developed hybrid (TilhanTec-SUNH-1) along with 2 female lines, 4 male lines and 3 hybrids using sunflower specific simple sequence repeat (SSR) markers. Methodology: Two parentages (ARM-243A and RGP-100) were utilized for the development of a new promising sunflower hybrid, TilhanTec-SUNH-1 (IIOSH-15-20). Performance of entry was assessed at 29 and 14 locations, respectively, during the kharif and rabi seasons over three years through All India Coordinated Trials (IHT, AHT-I & II) and a state multilocation trial at three locations. A total of nine quantitative observations were recorded. A total of 80 SSR primers were used on the 4 hybrids for DNA fingerprinting. Results: Considerable seed yield superiority (28.7% and 10.5%) was observed in AICRP trials over DRSH-1 and KBSH-44, respectively. Oil yield superiority was 27.1% and 27.3% compared to national checks DRSH-1 and KBSH-44. TilhanTec-SUNH-1 was found resistant (0%) to downy mildew and leafhoppers (1.1 grade) while tolerant to Alternariaster leaf spot. Four SSR markers, viz., ORS-57, ORS-203, ORS-1028 and ORS-598 can be confidently used for the identification of TilhanTec-SUNH-1 as well as for genetic purity tests. Interpretation: The results of this investigation revealed that TilhanTec-SUNH-1 is superior in terms of seed and oil yield and resistance to downy mildew and moderately resistant to leafhoppers and tolerant to Alternariaster leaf spot. It is notified and released by CVRC for commercial cultivation in rainfed conditions of the sunflower growing states of India.
