Group 1: Aerospace Industry - The Long March 5 series rocket, known as "Fat Five," is a significant product of China's aerospace ambitions, with a focus on reducing weight to lower launch costs and increase payload capacity [2][4] - Innovative double-sided milling processing proposed by a technician, Yao Yachao, addresses the issue of uneven stress during bending of large wall panels, enhancing production efficiency [4][6] - Yao Yachao's workshop has achieved a 100% qualification rate for processed parts over his 10 years of work, showcasing the high standards of quality in China's aerospace manufacturing [6][8] Group 2: Agricultural Research - Tianjin Cucurbit Research Institute is the only research institute in China focused on cucumber breeding, having developed multiple cucumber varieties that are widely adopted in the market [12][14] - The cucumber industry faced significant challenges due to a viral outbreak in 2022, prompting researchers to investigate and develop resistant varieties [14][16] - Han Yike, a leading cucumber breeder, has developed 23 new cucumber varieties, with a cumulative promotion area exceeding 600,000 acres, generating approximately 6 billion yuan in economic benefits [14][16] Group 3: Rice Breeding - Tianjin is a traditional area for japonica rice cultivation, with a focus on developing high-quality rice varieties to combat historical pest issues [19][21] - Over 40 years, researcher Yu Fu'an has developed several rice varieties that now cover over 80% of the rice planting area in Tianjin, significantly improving local agricultural productivity [21]

Core Viewpoint - The development of a new dwarf rice variety named "Xiao Wei" has achieved a yield of 410 kilograms per mu, demonstrating significant potential in rice cultivation and breeding [1][4]. Group 1: Research and Development - The research team at the China Rice Research Institute focuses on both normal and atypical rice phenotypes to unlock genetic secrets, utilizing molecular biology to enhance breeding techniques [2][3]. - The discovery of "Xiao Wei" stemmed from a 17-year effort involving gene mutation and hybridization, aiming to create a rice plant that can thrive in limited space while maintaining yield [2][3]. Group 2: Genetic Improvement - "Xiao Wei" initially had several deficiencies, including weak stems and underdeveloped grains, which required extensive genetic optimization to achieve its current form [3]. - The research process involves numerous mutation experiments and hybridization efforts, with a typical rice lifecycle taking 4 to 5 months and requiring at least six generations for trait stabilization [3][4]. Group 3: Broader Impact and Collaboration - The genetic resources of "Xiao Wei" have been shared with over 100 agricultural research institutions across China, fostering collaboration to explore its full potential [4]. - The ongoing efforts in rice breeding are supported by a significant collection of over 80,000 genetic resources stored in low-temperature facilities, which serve as a vital repository for research and development [5].
