ABSTRACT

A Field experiment was laid out at the field laboratory of department of Horticulture, Bangladesh Agricultural University for improving the local variety through conventional breeding methods of carrot. Under the experiments 6 accessions of wild carrot relatives (CWRS’s) viz. Ames 29084, PI 652410, PI 163235, PI 181052, PI 218076, PI269486 were used as improved lines and Prima agroflora (PA) and Bacilla agroflora (BA) used as local germplasm for adopting hybridization. After successful artificial pollination in and between the improved accessions with the local accessions and fifteen (15) derivatives were obtained which successfully produced seeds. Seed collected from these crossed plants were evaluated in this field experiments later. Significant improvements were found in the F2 generation and results from the derivatives comparison with the local varieties in respect of growth parameters as well as both root and seed yield components. Among the derivatives crossed accession no PI 181052 X PI 652410 gave maximum seed germination (58.34%), crossed accession PI 181052 X PA grown with maximum plant height and superior into the other growth parameters. The highest root yield was found 9.78 MT/ha in PI 269486 X PI 652410 comparison the lowest root yield was 0.68 MT from PI 269486 X PA derivatives. In case of seed production, the maximum seed yield per hectare was found 356.8 kg in check variety BA other than the derivatives. It was observed the improvements of the local varieties was promising for further improvement for carrot variety development in Bangladesh.

Highlights

• Wild carrots relatives (CWR) may be domesticated through hybridization
• Derivatives of carrots come from CWRs and Prima Agroflora and Bacilla Agroflora performed significantly while test cross.
• Derivatives from CWRs are more capable in a stressful environment.
