番茄是全球消费的第二重要蔬菜作物,凭借其富含抗氧化剂的植物化学物质和生物活性化合物。鉴定具有高抗氧化能力和营养丰富的植物化学物质的基因型对于改善人类健康至关重要。本研究旨在分析93种不同地理位置的抗氧化剂和营养化合物,高产,质量更好,耐逆性番茄基因型(杂种,家长线,近交系,和先进的线路)。在测试的基因型中检测到所研究的性状的显著变异(p<0.05)。主成分分析揭示了杂交的NIAB-Jauhar,铁娘子F1,NBH-258,AhmarF1,NIAB-Gohar,亲本H-24,B-25,AVTO1080,Astra和AVTO1003,以及品系LBR-17,AVTO1315,AVTO1311和Lyp-1在叶绿素等性状上表现优异,番茄红素,总类胡萝卜素,总抗氧化能力,总氧化剂状态,蛋白酶,α-淀粉酶和总黄酮含量。而杂种SurkhailF1,NBH-204,NBH-229,NBH-151,NBH-196,NBH-152,NBH-261,NBH-228,NIAB-Jauhar,NBH-256和NBH-255,线21354,AVTO1315,Newcherry,LA4097,AVTO1311和UAF-1与父母Naqeeb一起,NCEBR-5、M-82和LBR-10对可溶性总糖、减少糖,丙二醛,抗坏血酸,酯酶,过氧化物酶和超氧化物歧化酶。此外,在PC-I中,半确定和确定的番茄基因型以及阳性因子得分分别为3.184、0.015、0.325和0.186的亲本和品系类别,表现出更好的表现,如总叶绿素,番茄红素,总类胡萝卜素,总氧化剂状态,蛋白酶,α-淀粉酶,总抗氧化能力,酯酶和总黄酮含量。然而,在PC-II中,半确定和不确定的番茄基因型以及具有2.619、0.252和0.114的阳性因子得分的类别杂种,表现出更好的表现,如总可溶性糖,减少糖,叶绿素b,丙二醛含量,抗坏血酸,超氧化物歧化酶和过氧化物酶。在杂种中观察到杂种的杂种活力。上述在各性状中表现突出的番茄基因型可在育种计划中利用以改善番茄的营养品质,这可进一步改善人类健康。
Tomato is the second most important vegetable crop consumed globally, by the virtue of its antioxidant-rich phytochemicals and bioactive compounds. Identifying genotypes with high antioxidant capacities and nutritionally rich phytochemicals is imperative for improving human health. The present study aimed to analyze 21 antioxidant and nutritional compounds in 93 geographically diverse, high yielding, better quality, stress tolerant tomato genotypes (hybrids, parental lines, inbred lines, and advanced lines). Significant variation (p < 0.05) was detected for investigated traits among the tested genotypes. Principal component analysis revealed the hybrids NIAB-Jauhar, Iron-lady F1, NBH-258, Ahmar F1, NIAB-Gohar, the parents H-24, B-25, AVTO1080, Astra and AVTO1003, as well as the lines LBR-17, AVTO1315, AVTO1311 and Lyp-1 revealed superior performance for the traits such as chlorophylls, lycopene, total carotenoids, total antioxidant capacity, total oxidant status, protease, alpha-amylase and total flavonoid content. Whereas the hybrids Surkhail F1, NBH-204, NBH-229, NBH-151, NBH-196, NBH-152, NBH-261, NBH-228, NIAB-Jauhar, NBH-256 and NBH-255, the lines 21354, AVTO1315, Newcherry, LA4097, AVTO1311 and UAF-1 together with the parents Naqeeb, NCEBR-5, M-82 and LBR-10 exhibited significant contribution to the traits such as total soluble sugars, reducing sugars, malondialdehyde, ascorbic acid, esterase, peroxidase and superoxide dismutase. Moreover, the semi-determinate and determinate tomato genotypes together with the categories parent and line with positive factor scores of 3.184, 0.015, 0.325 and 0.186 in PC- I, exhibited better performance for the trait such as total chlorophylls, lycopene, total carotenoids, total oxidant status, protease, alpha-amylase, total antioxidant capacity, esterase and total flavonoid content. Whereas again the semi-determinate and
indeterminate tomato genotypes along with the category hybrid with positive factor scores of 2.619, 0.252 and 0.114 in PC- II, exhibited better performance for the traits such as total soluble sugars, reducing sugars, chlorophyll b, malondialdehyde content, ascorbic acid, superoxide dismutase and peroxidase. Hybrid vigor was observed in the hybrids for investigated traits. The aforementioned tomato genotypes showing outstanding performance in the respective traits can be exploited in the breeding programs to improve nutritional quality of tomato that can further improve human health.
