Phenotypic correlations were determined between fiber yield and some economic traits in ten lines of medium-fiber cotton Gossypium hirsutum grown in three different regions of Uzbekistan. It is noted that there is a direct relationship of average strength between the fiber yield and the length of the growing season.

Variety Trial

Goal. To evaluate bred multi-marker tomato lines for a set of economic traits. Results and discussion. The results of studying new multi-marker tomato lines in a competitive variety trial are given. Twelve lines were evaluated for the growing season length and its phases, traits of performance and chemical composition of fruits. It was revealed that according to the growing season length all the lines were early-ripening and gave yields 97-110 days after emergence. Line L-120/18 was selected by the shortest “emergence - the first fruit ripening” period (97 days) and by the shortest interphase “the first sprouts – anthesis” (52 days) and “anthesis - the first fruit ripening” (45 days) periods. In terms of performance, lines L-106/18 L-164/18 L-474/18 L-98/18 lines were the best, generating 2.6-3.5 kg of fruits per plant. The average fruit weight of the lines was lower than that of standard variety Karas and ranged from 40.5 g in line L-419/18 to 95.6 g in line L-106/18. As to the fruit number per plant (more than 24), lines L-419/18 L-164/18 L-474/18 L-473/18 L-106/18 L-98/18 L-125/18, and L-120/18 were distinguioshed. Biochemical assessments of tomatoes of the lines showed that most of the parameters under investigation were better in all the lines than those in the standard variety. The high content of soluble dry matter (6.8%) was found in line L-473/18; the total sugar content was the highest in lines L-473/18 (5.63%), L-99/18 (4.52%), L-106/18 (4.24%), L-102/18 (4.23%), and L-419/18 (4.23%); the vitamin C content was remarkable in lines L-125/18 (22.9 mg/100 g) and L-99/18 (23.0 mg/100 g); the titrated acidity was good in lines L-125/18 (0.75%) and L-474/18 (0.63%). Lines L-473/18 (15.6), L-99/18 (12.6), L-106/18 (11.8), and L-102/18 (10.8) stood out by their sugar-acid index. Conclusions. The study of new multi-marker tomato lines in the competitive variety trial revealed their peculiarities in expression of the major economic characteristics. We selected lines that were superior to standard variety Karas by the growing season length, perfoemance and fruit quality. Lines L-106/18 (sp, Aft, c, gf), L-164/18 (u, y, gf, B), L-98/18 (sp, u, Aft, gs, gf, j-2), L-125/18 (Aft, hp-2dg, alc, u), L-99/18 (sp, u, Aft, hp-1), and L-120/18 (sp, Aft , hp-1, u, o, j-2) were offered as sources for breeding. The expediency of using these lines also lies in the fact that, in addition to economic traits, they are carriers of mutant genes that which are easily identified and inherited by Mendel's simple laws, which facilitates their combination, significantly speeds up selection of desired genotypes and generation of forms with a set of specified traits.

Growing Season Length

Abstract The Scots pine is one of the most important species in European and Asian forests. Due to a widespread occurrence of pine forests, their significance in the energy and mass exchange between the Earth surface and the atmosphere is also important, particularly in the context of climate change and greenhouse gases balance. The aim of this work is to present the relationship between the average annual net ecosystem productivity and growing season length, latitude and air temperature (tay) over Europe. Therefore, CO2 flux measurement data from eight European pine dominated forests were used. The observations suggest that there is a correlation between the intensity of CO2 uptake or emission by a forest stand and the above mentioned parameters. Based on the obtained results, all of the selected pine forest stands were CO2 sinks, except a site in northern Finland. The carbon dioxide uptake increased proportionally with the increase of growing season length (9.212 g C m-2 y-1 per day of growing season, R2 = 0.53, p = 0.0399). This dependency showed stronger correlation and higher statistical significance than both relationships between annual net ecosystem productivity and air temperature (R2 = 0.39, p = 0.096) and annual net ecosystem productivity and latitude (R2 = 0.47, p = 0.058). The CO2 emission surpassed assimilation in winter, early spring and late autumn. Moreover, the appearance of late, cold spring and early winter, reduced annual net ecosystem productivity. Therefore, the growing season length can be considered as one of the main factor affecting the annual carbon budget of pine forests.
