Comparative Analysis of Some Wheat Genotypes Based on Plant Height Parameter

Abstract

The height of the plants is an important morphological parameter, in relation to the production of biomass, the randamnet of grains, carbon fixation, technological agronomic aspects. The study analyzed and characterized 25 wheat genotypes based on the parameter of plants (LH). The field experiments were located within ARDS Lovrin, agricultural year 2023 - 2024. The height of the plants varied between pH = 80.00 ± 1.43 cm (genotypes L_5040, L_5041, L_5045), and pH = 105 ± 1.43 cm (genotype L_5042). The data series presented a normal distribution, with r = 0.980. The mean calculated value was = 90.32 ± 1.43 cm. Compared to the mean value, ten genotypes presented values ​​superior to the average, and ten genotypes presented below average values, under statistical safety conditions. With values ​​higher than the average, 100 cm, and higher, were: L_5042 (DPH = 14.68 cm, ***), L_5048 (DPH = 12.68 cm, ***) and L_5035 (DPH = 9.68 cm, ***). Cluster analysis has grouped the genotypes based on similarity (Coph.Corr. = 0.757). In the series of recorded values, some wheat genotypes presented equal height, three genotypes at the value pH = 80 cm, four genotypes at pH = 85.00 cm, four genotypes at pH level = 90.00 cm, and five genotypes presented the value pH = 95.00 cm. In Quartila Q1 (Lower Quartile), five genotypes (L_5040, L_5045, L_5037, and L_5039) were framed, and in Quartila Q4 (Upper Quartile) four genotypes (L_5026, L_5048, and L_5042) were included. The other genotypes were grouped in the median domain (Q2, and Q3).
