ThesisItem Open Access ADAPTABILITY AND PATH ANALYSIS IN BERSEEM (Trifolium alexandrinum L.)(Mahatma Phule Krishi Vidaypeeth, Rahuri, 1997) Kusalkar, D.V.; Patil, F.B.Investigations were conducted for critical assessment of adaptability, associations and path effects in berseem. Twenty genotypes including two check varieties (Wardan and Mescavi) were evaluated at Rahuri, Maharashtra in three predictable environments (E^, E2» E3) during Rabi.1994- 95 and three cuts were taken in each environment. Plant height, number of tillers per plant and per meter length, L/S ratio, green and dry fodder yield per plant, crude protein content and green fodder yield per meter distance were studied. Significant G x E interactions were observed for all the characters studied in all the environments. Importance of linear component of G x E interaction was observed in the expression of plant height (in E^, E2 and over all environments), number of tillers per plant (in E^), number of tillers per meter length (in E2» E3 and over all environments), green fodder yield (in E^, E2 and over all environments), dry fodder yield per plant (in all environments) and green fodder yield per meter distance (in Ej, E3 and over all environments). Pooled deviation (nonlinear) effects were highly significant for all the characters except number of tillers per plant in E ^ environment. The genotypes viz., JHB-93-3 (plant height), JHB- 92-2 (number of tillers/plant, crude protein content), JHB- 93-4, HFB-135, Wardan and Mescavi (number of tillers/plant) had wider adability in nine environments (i.e. over all environments). Further, the genotypes viz., JHB-92-2, HFB- 135, Mescavi in all the three predictable environments (E^, E£ and E^)^txe stable for most of the characters including green and dry fodder yield per plant. The genotypes, BL-126 for number of tillers per plant, Mescavi for L/S ratio, BL-122 and JHB-93-2 for green fodder yield per plant in E2 environment, While, the genotype BL-126 for number of tillers per meter distance, JHB-93-4 for green and dry fodder yield per plant and protein content and Wardan for dry fodder yield and crude protein content in E3 environment appeared adapted to rich environment (i.e. with below average stability). Whereas, the genotypes,BL-130 for green forage yield and BL-102 for L/S ratio in E2 and E3 environments, respectively were adaptated to poor environment having above average stability. The correlation studies indicated the importance of all the characters except L/S ratio as they were significantly associated with green fodder yield per meter distance in all the three predictable environments. However, considering direct and indirect effects under various environments, the components such as plant height, crude protein content, number of tillers per plant and green fodder yield per plant appeared most important in the selection criteria aiming at improvement \r\ fodder yield of berseem.ThesisItem Open Access ASSESSMENT OF GENETIC DIVERGENCE IN WHEAT (Triticum aestivum L.).(Mahatma Phule Krishi Vidyapeeth, 2016) BANKAR MAHESH BAPURAO; Kusalkar, D.V.The present investigation “Assessment of genetic divergence in wheat (Triticum aestivum L.)” was undertaken to study the extent of genetic variability, heritability (broad sense), genetic advance, correlation and genetic divergence in 36 genotypes of wheat. The material was evaluated in randomized block design with two replications during Rabi-2014 at Post Graduate Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri.

Niphad, Rahuri and Savalvihir under timely sown irrigated (TSI) and late sown irrigated (LSI) conditions during Rabi-2013-14. The experimental material consist of twenty new bread wheat genotypes developed at Agricultural Research Station , Niphad and three check varieties. Experimental material was grown in a randomized block design with three replications over six environments. The mean sum of squares due to genotypes were significant for all the nineteen characters studied across the environments, which indicated the presence of substantial variation in the material studied. The analysis also indicated significant variation among the environments for all the characters. The values of G x E interaction were significant for all nineteen characters which indicated that genotypes interacted differently with environmental variation for the said characters. Highly significant values of mean squares due to environments (linear) for all the characters indicated that the linear responses of genotypes to environment differed significantly for the said characters; while mean square values due to G x E (pooled error) were also significant for all the characters.ThesisItem Open Access Genetic variability analysis and morphological characterizations of rabi sorghum (Sorghum bicolour(L)moench)germplasms(Mahatma Phule Krishi Vidyapeeth, Rahuri, 2006) Shinde, D.E; Kusalkar, D.V.; 631.7/MALThesisItem Open Access Genetics of Yield and Fibre Quality Characters in Interspecific Crosses of Cotton ( G.hirsutum L.x G.barbadense L.)(Mahatma Phule Krishi Vidyapeeth, Rahuri, 2013) Gawali, S.B.; Kusalkar, D.V.; 581.16/GAWThesisItem Open Access Identification of summer Groundnut (Arachis hypogaea L.)

Moench](Mahatma Phule Krishi Vidyapeeth, Rahuri, 2018) Ingle Anant Uttamrao; Kusalkar, D.V.Sweet sorghum production is affected by a wide range of biotic constraints, of which shootfly (Atharigona soccata) is the most important pest, which severely damages sweet sorghum crop during the seedling stage. Host plant resistance is one of the major components to control shootfly. To understand the nature of gene action for inheritance of shootfly resistance and juice yield, its component traits in sweet sorghum, we carried out the present experiment, entitled, “Inheritance of shootfly resistance in sweet sorghum [Sorghum bicolor (L.) Moench]”, in six basic generations, namely, P1, P2, F1, F2, B1 and B2’s of three crosses viz., SSV-84 x IS 18360, RSSV-269 x RSSV-260 and RSSV-493 x RSSV-167 during 2017. The six generations mean values of all three crosses indicated that, the F1 means were higher than mid parental mean values and comparable to better parent mean values in significant direction in respects of all the traits in present investigation, except days to 50% flowering and days to maturity, which indicated both partial or over dominance. The F2 means were estimated lower than the F1 mean values in all three crosses. The mean of backcross populations tended towards their respective parents. These result indicated the predominance of non-additive gene action which includes both dominance as well as epistatic interactions.ThesisItem Open Access Path Analysis and Correlation Studies in Summer Groundnut (Arachis hypogaea L.)(Mahatma Phule Krishi Vidyapeeth, Rahuri, 2015) Borate, V.S.; Kusalkar, D.V.; 581.16/BOR
