山西省普通菜豆核心种质普通细菌性疫病抗性的鉴定和评价
China Vegetables（2021）
Abstract
为了筛选和利用普通菜豆抗普通细菌性疫病资源,采用对生真叶穿刺接种法鉴定评价了151份山西普通菜豆初级核心种质的抗病性,并进行了抗性种质聚类分析.研究结果表明,对生真叶穿刺接种法可以作为一种快速有效鉴定普通菜豆普通细菌性疫病抗性的方法;通过鉴定,151份资源中包含抗病和中抗种质35份,占总数的23.2％;感病和高感种质116份,占总数的76.8％.筛选出的唯一的1份抗病种质F0001696可作为红芸豆品种改良和创制的优质亲本材料.聚类分析将35份中抗以上核心种质划分为3大类群:第Ⅰ类群包含生育期短、株矮、直立有限生长的19份种质,第Ⅱ类群包含生育期较长、株高、蔓生无限生长的4份种质,第Ⅲ类群包含生育期长、株高中等、蔓生或半蔓生无限生长的12份种质.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
