Selection of superior accessions of turnip (Brassica rapa var. rapa L.) based on tuber quality‐related characters

Abstract

Turnip ( Brassica rapa var. rapa L.) (syn. B. campestris L. ssp. rapifera Sinsk) is an important crop species belonging to the Brassicaceae family. The 185 accessions belonging to this crop were collected from several areas of Toodshak region in Isfahan province, Iran, and their tubers were cultivated under homogeneous conditions in loamy clay soil. The morphological traits of different organs of those accessions were evaluated. Significant variations were detected among the accessions studied based on the traits recorded. Tuber shape showed high variation and included globose, oblong, ovate, obovate, and fusiform. Also, tuber skin color was highly variable, including white, bicolor white–violet, light violet, and dark violet. Tuber weight ranged from 1.56 to 35.70 g, while total soluble solids (TSS) of tuber flesh ranged from 7.00 to 11.80%. Principal component analysis (PCA) showed that 18 components were extracted by explaining 74.88% of total variance. The dendrogram obtained based on all the characters measured clustered the accessions into two major clusters. Sixteen accessions were placed into the first cluster, while the remaining accessions were placed into the second cluster which was divided into six subclusters. High level of morphological variabilities was observed among the accessions, which is applicable and useful for B. rapa var. rapa breeding programs. Based on the commercial and quality traits, 17 accessions could be selected for direct cultivation. Also, the promising accessions identified here can be utilized directly in breeding programs for genetic enhancement of this crop.

Selection of superior late‐blooming almond (Prunus dulcis [Mill.] D.A.Webb) genotypes using morphological characterizations

“…Three characters, including branch leaf length, branch leaf width, and branch petiole length, formed the PC3, accounting for 5.86% of the total variance. PCA has been previously used to investigate the phenotypic diversity of almond genotypes (Asgari & Khadivi, 2021; Khadivi, Goodarzi, & Sarkhosh, 2019; Khadivi, Safdari, et al, 2019; Sakar et al, 2020; Sakar, Yamani, & Rharrabti, 2019; Sepahvand et al, 2015) and other plants (Khadivi et al, 2021; Khadivi & Mirheidari, 2021; Khadivi, Mirheidari, & Moradi, 2022; Khadivi, Mirheidari, Saeidifar, & Moradi, 2022; Moradi et al, 2022; Safdari & Khadivi, 2021).…”

Morphological characterizations of parsnip (Pastinaca sativa L.) to select superior genotypes

“…Based on the scatter plot generated using PC1 and PC2, the accessions were placed into four groups and most of them were placed in the center of plot (Figure 5). PCA has been previously used to investigate the phenotypic diversity of most plants (Khadivi et al, 2021; Khadivi, Mirheidari, & Moradi, 2022; Khadivi, Mirheidari, Saeidifar, & Moradi, 2022; Khadivi & Mirheidari, 2021; Moradi et al, 2022; Safdari & Khadivi, 2021).…”

Effects of variety on quality and taste of spontaneous fermented dried radish

“…Radish, known as Raphanus sativus L., is a species belonging to the genus Raphanus in the Brassicaceae family (Gamba et al, 2021), which is greatly consumed in Asia, Europe, America, and North Africa due to its availability in local markets, cheapness, and consumer preference (Khadivi et al, 2022). Radish is usually eaten directly, but placed too long prone to cause hollowness and mildew.…”
