Sweetfuel Project Methodology Breeding for drought
WP2: Breeding for drought prone environments
The general objective of this WP is to develop new lines or hybrids of sweet sorghum with
- (i) juicy stems with high total sugar content (>17%),
- (ii) good production of grain suitable for human or animal alimentation and high biomass with stem girth >2.5 cm,
- (iii) better resistance to drought with good adaptation to rainy and/or post rainy season in India and producing bagasse with a better digestibility, suitable for fodder use.
The specific objectives are to:
1. Identify promising sweet sorghum hybrids through multilocation testing
2. Screen sorghum core germplasm and reference collections for high and juice volume
3. Develop sweet sorghum hybrid parents for high grain and sugar yields for rainy and post rainy season adaptations
4. Develop high biomass and sugar yielding brown midrib (bmr ) hybrid parents
5. Develop stay green hybrid parents with drought tolerance
6. Demonstrate the economic advantages with sweet sorghum under rainfed situation
WP2 tasks are:
Task 2.1. Identification of promising sweet sorghum hybrids
Task 2.2. Screening of sorghum core germplasm accessions and reference collections
Task 2.3. Development of promising hybrid parents for high sugar and grain yields
Task 2.4. High biomass yielding brown midrib (bmr ) hybrid parents
Task 2.5. Stay-green hybrid parents with drought tolerance
