Evaluation of some F1C7 clonal potato genotypes in Bangladesh​

Abstract

An experiment was conducted at Breeder Seed Production Centre (BSPC), Bangladesh Agricultural Research Institute (BARI), Debiganj, Panchagarh during cropping seasons to investigate comparative potentiality of five clonal potato hybrids, 4.5 W, 4.15, 4.26 R, 4.27 and 4.40 for releasing as variety in the country. In the investigation two outstanding varieties, Diamant and Cardinal were used as check. All the genotypes under study expressed excellent plant vigour showing above seven score (at 1-10 rating scale). Plant height ranged from 58.73 to 68.20 cm. The highest tuber weight/hill was found at 4.26 R (763.7 g) which was statistically similar to 4.5 W (741.7 g) and 4.40 (670.3 g) while the lowest was found at 4.15 (537.7 g). The highest yield was found from clone 4.40 (29.57 t/ha) at 65 days after planting (DAP) which was statistically similar to all other genotypes except 4.27 (22.44 t/ha). Regarding yield the clones/varieties may be arranged in order to descending as 4.5 W (47.36 t/ha), 4.26 R (46.02 t/ha), 4.40 (44.69 t/ha), Cardinal (40.46 t/ha), 4.27 (40.23 t/ha), Diamant (39.81 t/ha) and 4.15 (35.83 t/ha). Among them clone 4.5 W and 4.26 R gave significant higher yield than Diamant and Cardinal. Therefore, these two genotypes could be selected for variety for Bangladesh condition with further trails in other parts of the country.
