Milestone C.4.1.2: Core collection of pearl millet evaluated in multilocations in India (HDU/CLLG/NARS,
2008)
Sets of pearl millet core collection consisting of 504 accessions and four control cultivars were sent to All India
Pearl millet improvement Program, Mandor for evaluation at five locations in India. Data is awaited from these
locations. The preliminary analysis at ICRISAT, Patancheru revealed that IPs 9496, 11584, 15010, 17554, and
17566 (60-62 days) were early flowering, IPs 8130, 10401, and 12650 (30-56 cm) were short statured good for
mechanical management and IP 12570 (210 cm) was good for fodder. IPs 5207, 5447, 10290, 11457, and 12338
(56 – 64 cm) had long spike length. IPs 7440, 8000, 10456, 10471, and 17753 (35-40 mm) had thick spikes.

Milestone C.4.1.3: Reference sets of chickpea and sorghum phenotyped for agronomic traits
(HDU/CLLG/CTH/BVSR, 2008)
300 accessions of chickpea reference set are being phenotyped for yield and other important agronomic and
morphological descriptors along with five control cultivars. Data recording is in progress.

Output target C.5: Mini core and or reference collections of staple crops and small millets evaluated to
identify trait specific germplasm (2012)
Activity C.5.1: Evaluate mini core and reference collections for resistance to important biotic stresses
Milestone C.5.1.1: Mini core and reference collections of chickpea germplasm evaluated for resistance to AB,
BGM, wilt, collar rot and dry root rot under controlled environment and field (SP/HDU/PMG/RKV/CLLG,
2008)
Chickpea mini core evaluated for diseases resistance: Chickpea mini core subset consisting of 211 accessions
were reevaluated to confirm their resistance to ascochyta blight (AB), botrytis gray mold (BGM), fusarium wilt
(FW), collar rot (CR) and dry root rot (DRR) diseases under controlled environment conditions at ICRISAT-
Patancheru. Standardized optimum conditions for individual diseases were used for evaluation. Accessions
were categorized and grouped based on their reaction to each disease in both tests.
Resistance to AB: High levels of resistance to AB were not found in mini core subset. However, three desi type
accessions ICC 1915, ICC 6306, ICC 11284 were identified as moderately resistant (3.1 to 5 rating) to AB.
Among these three accessions, ICC 6306 had a 100 seed mass of 25 g while the rest had
