Foliar blast disease in pearl millet (Pennisetum glaucum (L.) R. Br.) caused by Magnaporthe grisea once considered as a minor disease, has become major threat for pearl millet cultivation during recent decade in almost all pearl millet growing areas. The present study is an attempt to understand the inheritance of foliar blast resistance in pearl millet against the natural inoculum of Magnaporthe grisea and also against artificial inoculum of its devastating strain PMg_DI. The experiment was conducted at ICRISAT, Hyderabad and IARI, New Delhi during 2017-19. F2 and backcross populations derived from a susceptible genotype ICMB 95444 and two resistant lines PPMI-10018 and PPMI-2464 were used. Screening of individual plant in F1s, F2s, BCP1s (susceptible parent × F1) and BCP2s (resistant parent × F1) under field and controlled conditions indicated that the resistance is governed by a single dominant gene. The test of allelism was conducted by crossing the resistant parents. No segregation for resistance was observed in F2 generation when screened against the natural inoculum of Magnaporthe grisea and its strain PMg_DI. This indicates that both the resistant parents possess the same gene.

“…This reveals that if one of the parents is resistant to blast then you will get blast resistant hybrid, means blast resistance is governed by single dominant gene. Similar results were quoted by (Gupta et al, 2012;Pawar et al, 2016).…”

Thirty three hybrid parents of pearl millet (26 females and 7 males) were planted at ICRISAT, Patancheru during rainy season and 182 crosses were generated from 33 parents, planted in RCBD. Both parents and their hybrids were scored for blast disease using foliar blast severity scale 1 to 9. Among females 18 were found moderately resistant, 4 found resistant and 4 were showed susceptible reaction for Patancheru pathotype. Whereas, in case of males, 6 parents showed moderately resistant and 1 found susceptible. While among 182 hybrids, 28 hybrids were showed resistant reaction for blast, 126 hybrids were found moderately resistant and 28 hybrids were recorded susceptible reaction against Patancheru pathotypes. The present study reveals that the disease reaction of the parents and F 1s gives us the preliminary information about inheritance of blast and resistant parents could be either used in the crossing programs to develop blast resistant hybrid parents or to diversify the genetic base for blast resistance in future pearl millet hybrids.

“…Hybrids, ICMA 96666 × RIB 37-40 S/17 (-8.68 %) and ICMA 94111 × RIB 3135-18 (-6.39 %) recorded maximum negative standard heterosis(Table 2). Similar findings were reported by Pawar et al (2015).Tallness is desirable in pearl millet, the hybrids possessing positive heterotic effects were therefore considered to be superior.The highest positive significant heterobeltiosis was recorded by hybrid ICMA 96666 × RIB 16296 (51.38 %).The standard heterosis for plant height ranged from -4.60% (ICMA 97111 × RIB 37-40 S/17) to 14.77% (ICMA 96666 × RIB 13-16 S/17). Highest positive significant standard heterosis was recorded by hybrid ICMA 96666 × RIB 13-16 S/17(14.77 %) followed by hybrid ICMA 97111× RIB 17 S/109 (14.39 %) (Table 2).…”

In present study Line x tester analysis was carried out to estimate all three types of heterosis (heterobeltiosis, averageand standard heterosis) for identification of superior cross combinations of pearl millet [Pennisetum glaucum (L.) R. Br.].Crosses attempted between 10 testers and four male sterile lines during summer, 2019. Forty hybrids along with four male sterile lines, 10 testers and check MPMH 17 were grown at Research farm of AICRP on pearl millet, Mandor (Jodhpur) Rajasthan during kharif, 2019 and evaluated for thirteen characters. Analysis of variance revealed that sufficient genetic variability present among parents and hybrids for all the studied characters. The results indicated presence of significantly high heterosis in desirable direction for all the characters except grain yield per plant and harvest index (standard heterosis) and protein and iron content (heterobeltiosis). The hybrids, ICMA 94111 × RIB 37-40 S/17 and ICMA 96666 × RIB 16300 showed positive standard heterosis for grain yield per plant with desirable negative standard heterosis for days to 50 % flowering. The hybrid, ICMA 97111 × RIB 17 S/109 showed significant positive standard heterosis for plant height, panicle diameter, test weight and stover yield per plant over check MPMH 17.Hybrids, ICMA 96666 x RIB 16300 and ICMA 94111 x RIB 37-40 S/17 also had higher level of iron content and hybrid ICMA 96666 x RIB 16300 additionally had higher protein content.
