Abstract

During the period from 1984 to 2014, our scientific school (consisting of 35 candidates and 12 doctors of science by 2018) developed a new theory of the ecological genetic organization of quantitative traits (TEGOQT). The theory is based on the discovery of a new epigenetic phenomenon, a change in the gene product profiles under a quantitative trait with the change of limiting environmental factor. A total of 24 important results and 10 techniques capable of eliminating the “bottlenecks” of traditional yield, increasing breeding technologies originated from the theory. TEGOQT gave rise to 16 innovative technologies for the construction of cutting-edge crop varieties characterized by high yield and product quality, which have been experimentally tested on many crops, and were tens and hundreds of times more effective than traditional yield increasing breeding technologies. This study describes the first among these 16 technologies, which is an important group of technologies for rapid (without alternation of generations) identification of the most productive genotypes during selection in segregating and wild populations. This group of technologies is based on the TEGOQT consequences, namely, the principle of background traits and the principle of “orthogonal” identification of maximum positive contributions to the yield of seven open genetic physiological systems (GPSs), including attraction; microdistribution of macronutrients between the spike grain and chaff; adaptability (drought, heat, frost, cold, salt tolerance, etc.); horizontal immunity; “paying” with dry plant biomass for low doses of soil nutrition (N, P, K); tolerance to phytocoenosis overcrowding; and genetic variability of the duration of ontogenetic stages.

在分离和野生植物种群选择中快速(无代交替)基因型鉴定的家用物理仪器设计

摘要

在1984年至2014年期间,我们的科学学院(到2018年由35名候选人和12名理学博士组成)开发了一种新的定量性状生态遗传组织理论(TEGOQT)。该理论基于一种新的表观遗传现象的发现,即随着限制性环境因素的变化,定量特征下基因产物图谱的变化。共有24项重要成果和10项技术能够消除传统产量的“瓶颈”,增加了源自该理论的育种技术。TEGOQT提出了16项创新技术,用于构建具有高产量和高产品质量特征的尖端农作物品种,这些技术已经在许多农作物上进行了实验测试,并且比传统的增产育种技术有效数十倍甚至数百倍。这项研究描述了这16种技术中的第一种,这是在隔离和野生种群选择过程中快速(无世代交替)鉴定最有生产力的基因型的重要技术组。这组技术基于TEGOQT的结果,即背景特征原理和“正交”识别对包括吸引力在内的七个开放遗传生理系统(GPS)的产量产生最大正贡献的原理。穗粒和谷壳之间大量营养素的微量分布;适应性(干旱,高温,霜冻,寒冷,耐盐性等);横向免疫 用干植物生物量“支付”低剂量的土壤营养(N,P,K);对植物群落过度拥挤的耐受性;发育阶段持续时间的遗传变异性。
