Abstract/ Executive Summary:

Among the five promising clones the highest number of tillers of 200.60 x 1000 ha-1 and 194.50 x 1000 ha-1 was obtained in the clone I 131-97 in both early and late planting time respectively followed by I 202-97 (171.70 x 103 ha-1 and 166.40 x 103 ha-1). Clone I 131-97 produced maximum number of millable cane of 120.90 x 1000 ha-1 and 112.20 x 1000 ha-1 both in early and late planting time respectively followed by I 202-97 (100.02 x 1000 ha-1 and 95.75 ha-1). The clone I 131-97 gave the highest cane yield (82.32 and 78.90 t ha-1 respectively) in both the early and late planting time. On the contrary the lowest yield was found in I 98-98 (47.56 t ha-1). The data on pol % cane in early planting was found statistically identical but it was significant varied in late planting. However, clone I 131-97 gave maximum pol % cane in both early and late planting. The result of the experiment showed that clones I 131-97 and I 202-97 performed better than the other clones both in November and February transplanting in all respect. So, these two clones may be recommended for commercial cultivation.

Keywords: Clone, Tiller, Millable Cane, Pol%

Location: BSRI Farm

Start Date: 15/10/2004

End Date: 20/12/2005

Program Area: Variety and Species

Non-commodity: Performance

Objectives:

i). To find out the optimum time of planting/transplanting for advanced promising clones of sugarcane as plant and ratoon crop.

ii). To find out the best-promising clone for obtaining higher canes and sugar yield.

iii). To study comparative performance of different promising clones under STP technique. iv)To provide NSB with necessary information regarding the clone under study.

Methodology:

BSRI developed promising clones I 98-98, I 110-98, I 131-97, I 142-98 and I 202-97 along with standard variety Isd 34 along with standard variety Isd 4 were observed in the experiment. Single budded bed settlings of 5-6-leave stage were transplanted in October, 2004 and February, 2005 for early and late planting respectively. The plant spacing was 100 cm x 45 cm and 100 cm x 30 cm respectively. The experiment was conducted at BSRI farm in split plot design with three replications. Recommended doses of fertilizers and other cultural practices were done as and when necessary.

Total Budget (Tk.) : 45,000.00

Achievement/Findings:

The results of this study will provide sufficient data and information about the promising clones for submission to the National Seed Board (NSB) for evaluation. The farmers may be benefited through growing the better-performed varieties (after release) in stipulated time on the basis of results of this experiment.
