Summary
The cultivation of vegetable crops involves various selection methods to improve introduced species such as potatoes, tomatoes, and capsicum. Asexual propagation through clonal selection is common, producing cultivars like Kufri Red potato and Black Beauty brinjal. Self-pollinated crops utilize pure line and single plant selection to stabilize superior genotypes, exemplified by cultivars like CO-1 tomato and Pusa Makhmali okra. Cross-pollinated crops benefit from systematic selection methods, including mass selection and line breeding, to enhance populations, leading to new cultivars like onion and cauliflower. Recurrent selection focuses on concentrating favorable genes, while hybridization generates genetic variability for improved traits. The development of hybrid varieties involves selecting parents, testing their combining ability, and producing F1 hybrids through methods like emasculation and hand
