“…Hence, these genotypes can be used as variety or choice of parent for hybridization programme. The results are in agreement with Sharma et al, (2012), they evaluated the pigeonpea to identify the resistance to FW under artificial field epiphytotic conditions. Sharma et al, (2013) identified combined resistance to FW and SMD in 54 lines, out of 3000 germplasm evaluated for three consecutive years during.…”

The material for study of genotype x environment (G x E) interaction comprised of 23 genotypes, which were tested in four environments, during kharif-2012 and 2013 at two locations in Agricultural Research Station, Kalaburagi and Raddevadgi located in north eastern dry zone (Zone 2) of Karnataka. The experiment was laid out in lattice design with two replications. Highly significant differences among genotypes were observed for all the characters except number of pods per plant and yield per plant. Environmental +(Genotype x Environment) interaction was significant for days to 50 per cent flowering, day to maturity, plant height, pod bearing length, number of pods per plant and seed yield per plant. The variance due to pooled deviation was highly significant for all the characters which reflect the presence of sufficient genetic variability in the material. Stability parameters for seed yield per plant indicated that ASHA(ch) was stable and desirable, followed by RVK-275 and GRG-811 which were specifically adopted for favourable and poor environments respectively. Two years of field screening for Fusarium wilt (FW) and Sterility Mosaic Disease (SMD) yielded three genotypes viz., GRG-811, GRG-2009 and ASHA for resistance to Fusarium wilt and moderate resistance to SMD. Hence, these genotypes can be used directly as a variety or choice of parent for hybridization programme.

“…Mini core collections of ICRISAT mandate crops such as peanut, pigeonpea and chickpea have become international public goods (IPGs) and are now being used by National Agricultural Research System (NARS) researchers in 20 countries. For example, in pigeonpea, sources of combined resistance to Fusarium wilt and sterility mosaic diseases (ICPs 6739, 8860, 11015, 13304 and 14819) were identified from the mini core collection (Sharma et al 2012). Earlier studies indicated useful variation in mini core to various biotic and abiotic stresses as in chickpea (Kaul et al 2005;Johnson et al 2007).…”

Late leaf spot (LLS) (Phaeoisariopsis personata) and rust (Puccinia arachidis) are major foliar diseases of peanut causing significant losses worldwide. Identification and infusion of resistance into peanut cultivars is important in the management of these diseases. The present study therefore aimed at screening the peanut mini core collection to identify potential sources of resistance to these diseases. Two separate field experiments were conducted for screening LLS and rust under artificial epiphytotic conditions during rainy seasons of 2012 and 2013 at ICRISAT, Patancheru, India. The trials were laid in a randomized complete block design on beds with three replications. Data on LLS and rust disease severities were collected using 1 to 9 scales at 75, 90 and 105 days after sowing (DAS), and pod yields were recorded at harvest. Results indicate significant variations among accessions for LLS and rust resistance. Mean of 2 years study revealed that 53 accessions were moderately resistant (MR), 86 accessions were susceptible (S) and 45 accessions were highly susceptible (HS) to LLS. For rust disease, 10 accessions were resistant (R), 115 accessions were with 'MR' reaction and 59 accessions with susceptible (S) reaction. Six superior accessions in terms of combined disease resistance and yield (ICGs 4389, 6993, 11426, 4746, 6022, 11088) were selected and the disease progress curves, for each, were generated. Highest yields were recorded with ICG 11426 in LLS and rust plots. Overall, our results indicate that these six accessions can be potential sources of LLS and rust resistance.

“…Hybrid lines derived from interspecific crosses involving C. acutifolius and C. platycarpus have shown resistance to Patancheru isolate of PPSMV under field conditions (Mallikarjuna et al, 2011). Recently, new sources of resistance to FW and SMD were identified in a minicore collection of pigeonpea germplasm at ICRISAT (Sharma, Rameshwar, & Pande, 2013;Sharma et al, 2012). High level of resistance to SMD was found in 24 accessions, which originated from India, Italy, Kenya, Nepal, Nigeria, the Philippines, and the United Kingdom.…”
