“…The use of resistant cultivars is the most effective, efficient, safe and practical method of obviating loss in crop yield. Inherent resistance or tolerance of crop plants to pathogens is the safest, economical and eco-friendly disease management approach to cope up with the problem [15]. SMH4 was observed to show resistance towards Turcicum leaf blight and common rust.…”

Maize is one of the most important cereal crops of Kashmir Valley where it serves as a source of food, feed, fodder and industrial raw material, providing enormous opportunity for crop diversification, value addition and employment generation. However, the average productivity of maize in Kashmir Valley is quite low (1.5 t ha-1) when compared to the national productivity (2.5 t ha-1). The development, dissemination and adoption of high yielding, early maturity, cold tolerant maize hybrids can serve as the most economical, effective and coherent approach to contribute significantly towards increasing maize production in Kashmir Valley. A single cross hybrid SMH4 (Shalimar Maize Hybrid 4) has been developed to enhance the maize productivity in high altitude agro-ecologies of the Valley. SMH4 possesses very high yield potential of about 7.0-8.2 t ha-1 compared to 2.5-4.0 t ha-1 as realised by the predominantly grown landraces in hilly agro-ecosystems. The hybrid revealed the grain yield superiority of about 23.61% and the stover yield superiority of about 15.77% over the commercial check viz., Shalimar maize Hybrid 1. The variety is resistant to Turcicum leaf blight and common rust, besides showing resistance to stem borers and cut worms. SMH4 has a very good acceptability by farmers for its high yield potential (both grain and fodder), better seedling vigour and early maturity. SMH4 with the traits like cold tolerance and early maturity can play a potential role in enhancing the economy of maize growers under high altitude ecologies of Kashmir Valley. The development, upscaling and mass adoption of SMH4 in temperate agro-ecologies will lead to socio-economic upliftment of small and marginal farmers through increase in production, productivity and farm profitability.

“…The use of resistant cultivars is the most effective, efficient, safe and practical method of obviating loss in crop yield. Inherent resistance or tolerance of crop plants to infection by the pathogen can most likely be a safe alternative and most economical and eco friendly disease management venture (Kumar et al, 2011). The benefit cost ratio was estimated by calculating total cost of cultivation and the net returns of both the varieties on hectare basis.…”

In temperate mountain agro-ecologies of India, cultivation of landraces and farmer's varieties using traditional methods is the main reason for low productivity of maize in potential niches. Painstaking efforts made at Mountain Crop Research Station, Sagam during kharif 2008 and 2009 resulted in two modern, high yielding maize composites viz., Shalimar Maize Composite 3 (SMC-3) and Shalimar Maize Composite 5 (SMC-5) with all the traits liked by the resource poor and marginal farmers. SMC-3 and SMC-5 showed grain yield superiority of 10.5 and 14.8% over the best commercial check (C15) and 42.9 and 48.7% superiority over local check, respectively. SMC-3 variety also resulted in 6.6% and 49.65% increase in stover yield over commercial check (C15) and local check, respectively. On the otherhand, SMC-5 showed 12.3 and 58.31% superiority in stover yield over commercial check and local check, respectively. Thus, both these varieties gave higher net returns and B:C ratio visa -vis check. Further, they showed moderate resistance against Turcicum leaf blight and common rust and resistance to stem borer, blue beetle and aphids. Application of 100% recommended dose of fertilizers long spacing of 60×20 cm 2 can be recommended as it resulted in significantly higher grain yield. SMC-5 contained elevated levels of tryptophan (20%), lysine (46%) and sugar contents (16%) over commercial check. The mass adoption of farmer preferred and reasonably priced, high yielding composite varieties can give a boost to maize productivity and profitability.

“…The study indicated that disease severity was always higher in Nagenahalli which appears to have a more conducive environment for disease development compared to Varanasi. Over-all more resistant inbreds (HKI-586, HUZM-53, CM-145, V-336, V-338, HKI-PC- [25] reported that virulence pattern of the TLB Pathogen from Almora changed, as inbreds CM 138, CML 235 and NAI 135, which showed a different resistant reaction over the two different locations. These results indicated changes in the virulence pattern of the pathogen as well as the impact of the environment.…”

Maize is the leading cereal crop worldwide with wide adaptability and high productivity potential. Foliar diseases are arguably the major biotic constraints for maize yield. Turcicum Leaf Blight (TLB) is considered to be the most persistent and destructive maize disease among various foliar diseases. The present study is an attempt to screen forty maize inbreds for resistance against TLB under artificially inoculated field conditions. The experiment was conducted in two different environments, viz. Varanasi (E1) and Nagenahalli (E2) to know the disease reaction of maize inbreds for two successive years. Screening of 40 maize inbreds revealed, 10 resistant, 13 partial resistant, 7 partial susceptible and 10 susceptible in Varanasi whereas at Nagenahalli, 3 resistant, 6 partial resistant, 14 partial susceptible, 7 susceptible and 10 highly susceptible genotypes. Based on this study, the selected resistant lines will be used in future breeding programs and could potentially be used to develop promising genotypes with suitable levels of resistance.
