Plant Breeding

Breeding of asexual propagated crops are divided into four main groups. Flowerless or sterile Flowers but rarely set seed Normally seeds produce but propagated vegetatively Apomicts – reproduce asexually through the process of apomixis. Breeding methods of asexual propagated plants. Clone selection Hybridization and Clonal selection. Mutation breeding Clone selection Clones are always propagated and … Read More “Breeding of asexual propagated crops” »

Breeding of cross pollination crops

March 10, 2023May 10, 2023 Janith Piumal No Comments

Plant Breeding

Cross pollinated plants species have different gene pool structure and extent of genetic recombination. genes are shuffled every generation, in self pollinated crops variety developed as improved population. (inbred lines),in cross pollination plants are developed as hybrid varieties (HYB). There are two methods for breeding of cross pollinated plants. Selection methods – develop open pollination … Read More “Breeding of cross pollination crops” »

Marker Assisted Selection

Plant Breeding

Plant breeding improves the genetic performance of the plants. Creation of the plant variety better than previous plants. Conventional breeding is based on the phenotype and marker assisted selection breeding is based on the genotype. Limitation of the conventional breeding Genotype is often interact with the environmental condition. phenotyping procedure is expensive and time consuming … Read More “Marker Assisted Selection” »
