With the continuous deepening of quality education and new curriculum reform, the integration of production and education, as a brand new educational concept, has been paid more and more attention, especially in various colleges and universities, where the integration of production and education has played an extremely important guiding role. The new business professional group established based on the integration of production and education can not only further deepen the cooperation between schools and enterprises, but also deepen the cooperation between schools and enterprises. An integrated and sustainable development path can also be built to the greatest extent possible. Therefore, the article first of all, based on the integration of production and education to build a new business professional group of the significance of in-depth analysis; On this basis, the main measures for the construction of new business specialty group based on the integration of production and education are put forward.

Lifelong learning is the core content of university education work in the new period, and it is also the basic task of education work in colleges and universities. The second classroom is a kind of organized and planned educational and practical activities aiming at cultivating students' extracurricular ability and comprehensive quality. In the context of the new era, emphasizing and strengthening the construction of the second classroom in colleges and universities is an inevitable requirement for improving the quality of ideological and political education in colleges and universities. At present, there are still some problems in the moral education of the second classroom in colleges and universities in China. In order to enhance the effect of moral education in the second classroom of colleges and universities in the context of the new era, it is necessary to make a clear target positioning of the moral education of the second classroom, improve the process between the second classroom and the first classroom, and establish a three-dimensional system of moral education in the second classroom, so as to enhance its infectious and persuasive power.

Employment guidance is an important way for employment education in colleges and universities, and it is also an important educational process. Strengthening the employment guidance in colleges and universities is necessary to alleviate the structural contradiction of employment and serve the talent cultivation of schools, as well as to enhance the employability of college students and serve the growth and success of young students. This paper focuses on the problems of employment guidance in colleges and universities in the new era, and proposes countermeasures to solve them in four dimensions: system construction, precise service, regional coordination and employment capacity enhancement.

The study evaluated 33 accessions of groundnut in the field, consisting of 23 landraces from Nasarawa communities in Nigeria and 10 inbred lines. Assessment entailed the determination of plant survivorship, yield related parameters and pathological indices while genetic diversity study was undertaken using SSR and RAPD molecular markers. Data analysis was done on the Minitab 17.0 software. Significant variability was noted in all traits except in pod sizes, seed sizes and % infected seeds. About 33.3% of the accessions had a survival rate of ≥ 70.0% where 9/10 Inbred lines were found with overall yield (kg/ha) ranging from 4.0 ± 1.6 in Akwashiki-Doma to 516.8 ± 46.9 kg/ha in Samnut 24 × ICGV–91328. Five accessions (15.5%) had pathological indices of zero indicating no traces of any disease of any type and they included one landrace called Agric-Dazhogwa and four Inbred lines: Samnut 25 × ICGV–91317, Samnut 26 × ICGV–19324, Samnut 26 × ICGV–91328 and Samnut 26 × ICGV–91319. Coefficients of yield determination R2 by survivorship and pathological index were 50.6% and 15%, respectively. A fit model was established (Yield in kg/ha = –146 − 7.94 × Pi + 5.88 × S). Susceptibility to diseases depends on the type of variety (χ2(32) = 127.67, P = 0.00). Yield was significantly affected by BNR@30 (F = 5.47, P = 0.025, P < 0.05) and DSV@60*RUST@60 interaction effect (F = 4.39, P = 0.044, P < 0.05). The similarity coefficient ranged from 28.57 to 100 in plant morphology. Four varieties had no amplified bands with SSR primers whereas amplified bands were present only in four landraces accessions using the RAPD primer. The dendrogram generated by molecular data gave three groups where genetic similarity ranged from 41.4 to 100.0. The Inbred lines were noted for their high survivorship, good yield and disease resistance. Samnut 24 × ICGV–91328, an inbred line, had the highest yield but was susceptible to diseases. Among the landraces, Agric-Musha, Bomboyi-Dugu and Agric-Dazhogwa were selected for high survivorship and disease resistance. The selected inbred lines and landraces are valuable genetic resources that may harbour useful traits for breeding and they should be presented to the growers based on their unique agronomic values. The highest yielding inbred lines should be improved for resistance to late leaf spot diseases while the outstanding landraces should be improved for yield.
