| dc.description.abstract | The present investigation aimed at studying the mean perfrv-J-irl.‘ and stability of some prereleased hybrids of rice alongwith commo:variety and some released and pre released varieties of groundnut ; by Acharya N.G. Ranga Agricultural University. The data for the stu;;. given by Eberhart and Russell (1966) and Perkins and Jinks (196E) __ used to evaluate the mean performance and stability for the genotypes .V under different environments. AMMI (Additive main effects and multipgaj ‘3 interaction) model was carried out to study the genotypes x envirr,;»l-,Vl.:;.:. interaction. Evaluation of mean performance of different rice genotypes Tina-3:4 that MTU HR—2034 was superior among all the test genotypes follOi.-..;;;-; MTU FIR-2037 followed by common check variety MTU—2067. The 1-1,: yield was recorded by MTU 1—1R—2024. Study on stability of different rice genotypes tested over? environments revealed that the hybrids MTU HR-2035 and MTU Eli-gin were stable. (23 ( II Evaluation of mean performance of different groundnut varjiw showed that in k/ICII"if-l990, the genotype K—l34 topped among all tl.:5 i2=t genotypes followed by lCGS—ll followed by lCG (FDRS)-4. The lowest yield was recorded by TCGS—l. In khan/L199] also K—l34 registered highest yield and lCG(FDRS)-10 recorded the lowest yield. Studies on stability of different groundnut genotypes tested over eight locations during kharijll990 revealed that the genotypes K- 134 and SVGS—l were stable and TCGS—3 was having good adaptability but with low mean yield. The genotypes JL—24 and SVGS—l were having good stability with high mean yields among the IS genotypes tested over 12 locations during kharI'f—l99l. Here TCGS—l was also stable with mean yield nearer to grand mean. For all the three studies (hybrid rice /r/)a/‘[f—1995, groundnut kl'zarif-IQQO ' and groundnut klzarIf-199l) ANOVA revealed significant G x E interaction. By partitioning the G x E interaction, both linear and non linear components were found to be significant. Moreover the non linear component was higher in magnitude than the linear component Evaluation of rice hybrids over five locations during k/zarifll‘JQS using AMMl model showed that the hybrids MTU HR—2028, MTU HR—ZOZQ, MTU FIR-2032, MTU HR-2018 and MTU HR—2033 were differing with the genotypes MTU HR—2037, MTU HR-2034 and MTU-2067 for main effects. The hybrids MTU HR-2026, MTU HR—ZOZS, MTU HR—2032, MTU HR-2018 and MTU HR—2033 differed with the hybrids MTU [TR—2034, MTU HR-2036 and MTU HR-2037 both for main and interaction effects. The environment E2 and the hybrids MTU HR-2024 and MTU ELK—2029 had very small interaction effects. The environments E4 and E5 had positive interaction with the genotypes MTU HR-2026, MTU FIR-2028, MTU HR-2032, MTU HR—2033, MTU HR—2018 and common check MTU-2067 and negative interaction with other hybrids, The interaction becomes vice versa for the environments E1 and E3. Evaluation of groundnut genotypes over eight environments during klzarif—l990 showed that the genotypes TMV-B. TCGS-l, SVGS-l and TPT—2 were differing with the genotypes Girnar—l, lCG(FDRS)-4 and [CG (FDRS)—l0 for their interaction effects, The environment E6 and the genotype TPT—l were having small interaction effects. The environments E4, E7 and E8 were having positive interaction with the genotypes TPT—l, TPT—Z, K—134, SVGS-l, TCGS-l, TCGS-3, JL—24 and TMV—2 and negative interaction with other genotypes. The interaction becomes vice versa for E1, E2, E3 and E5. Evaluation of groundnut genotypes over 12 locations during klrarif1991 showed that the genotypes lCG (FDRSWL lCG (FDRS)—10 differed with Girnar-l, ICGS-‘l‘l 811d JL-24 for their interaction effects. The genotypes TPT~1, TPT-2, ICGS'3, SVGS-l, ICGS—ll and JL—24 differed among themselves neither for main effects nor for interaction effects. The environments E2 and E6 and the genotype Kadiri—3 had very less interaction effects The environments E7, E8, E9, E10 and E12 had positive interaction with the genotypes lCG (FDRS)-4, ICG(FDRS)—|O, K—134, lCGS—l and lCGV-86699 and negative interaction with others. The interaction becomes vice versa for the remaining environments. Comparision of three models revealed that the AMMI model is accurate in partitioning the G x E interaction and it is facilitating the yield estimation. Regarding the evaluation of stability Eberhart and Russell (1966) and Perkins and Jinks (1968) models were good. | en_US |
