Abstract/ Executive Summary:

In drought prone areas of Bangladesh, yield of sugarcane is low due to lack of drought tolerant varieties. To extend sugarcane cultivation in marginal land and drought prone areas development/screening of drought tolerant varieties are important. Therefore, in this trial sugarcane clones will be screened out having capabilities to grow under drought stress condition. Screened and released 7 (Isd 20, Isd 35, Isd 36, Isd 37, Isd 38, Isd 39 & Isd 40) highly tolerant sugarcane varieties having built-in potential for cultivation in drought prone areas of Bangladesh

Keywords: Sugarcane, Drought, Yield

Location: BSRI (PVC pipe), RSRS (Thakurgaon) and Godagari (Rajshahi)

Start Date: 01-01-1995

End Date:

Program Area: Resource Development and Management

Commodity: Sugarcane

Objectives:

To select sugarcane clones with superior tolerance to drought.
To find out morphological and physiological basis for drought tolerance to sugarcane.
To identify parents to use in further crossing programme to develop drought tolerant varieties.

Methodology:

The BSRI bred clones as well as locally collected clones will be included in the study to be carried out in the following phase: I. Testing under induced drought stress condition. II. Field-testing. I. TESTING UNDER INDUCED DROUGHT STRESS CONDITION: In this case, the test clones/varieties will be grown in PVC pipe and subjecting them to artificially made drought stress by using PEG (Polyethylene Glycol 6000). Sugarcane clones of ZYT I, II, III and other selected clones will be compared with known drought stress tolerant commercial varieties. A separate set of those clones will be maintained as check. II. FIELD TESTING: BSRI bred sugarcane clones of ZYT I, II, III and other selected clones/varieties will be tested under field condition. Screening of clones/varieties will be done subjecting them to field testing in drought prone areas (Barind tract, Rajshahi; RSRS, Thakurgaon) in order to obtain more information on their yielding potential under field drought stress condition. PROCEDURE : Single-budded setts of different test clones will be planted into 60x10cm PVC pipes each containing 6 Kg soil. Normal intercultural operations including watering, fertilization, weeding etc will be done. Four months after planting PEG or Manitol osmotica will be applied to 50% PVC pipes containing plants. The remaining 50% plant will serve as control. In case of field testing two budded setts will be planted to normal drought prone areas such as Godagari (Rajshahi) and RSRS (Thakurgaon) in the month of late October.
