Studies on Genetic Variability for Morphological And Qualitative Characters in Bael (Aegle Marmelos Correa) in Western Uttar .pradesh Conditions

Abstract

An investigation entitled '"Studies on genetic variability for n1orphological and qualitative characters in bael (A.egle 1narn1elos Correa) in Western Uttar Pradesh conditions." was carri~d out at I~orticultural Research Centre along with Lab. of Deptt. of 1-Iorticulture of SVJ>UA&T" Meerut during 2013-14 and 2014-15 to study the genetic variability .. interrelationship and genetic divergence in fiJty genotypes of bael. The study involves PCV &. GCV" heritability & genetic advance, correlation &. path coe1licicnts analysis and genetic div~rgencc (02 ) based on sixteen n1orphological and qualitative characters under t\VO individual environn1ents and con1b.ined over environn1ents (pool data of both environtncnts). Study revealed highly significan~ diilerences an1oi1g the genotypes" the estimates of PCV were found higher than GCV for all the studied traits. '"rhc heritability estin1ates in broad sense and genetic advance wer~ high for fruit yield per tree" fruit pulp weight~ fruit weight" seed \Veight per J)·u.it~ nun1ber of fruits per tree~ ascorbic acid and skull weight in both the individual cnvironn1ents and con1bined over environntents. Correlation studies indicated the higher n1agnitude of genotypic correlation than the corresponding phenotypic ones. Yield per tree had positive and highly significant correlation with fruit pulp weight fruit weight" fruit dian1eter~ fruit length, ascorbic acid~ reducing sugar~ total sugar" non reducing sugar and total soluble solids at phenotypic and genotypic levels. l)ath coefficient analysis revealed highest direct positive efTcct of fruit weight'\ nun1ber of fruits per tree'l fruit pulp 'vveight and ascorbic acid to\vards fruit yield per tree. Genetic divergence studies grouped all the genotypes into eight diverse clustt;rS under botJ1 environn1ents and cotnbined over envh·onn1ents. Clustering pattern cl1anged \Vith the environn1ents w·hich indicated that 0 2-statistics are highly intluenc~d by the environn1ent. Maxin1un1 genetic divergence \Vas observed for fruit pulp \veight fruit \Veight" fruit length, ascorbic acid, nun1ber of fruits per tree and skull weight. Over alt divergence study suggested that crosses involving genotypes \1B-28 Pant Aparn~" VB-~3" Pant Shivru1i and Pant Sujata with genotypes VB-45~ VB-4 .. VB-11 and YB-1 for gettn1g desired tra11sgressive segregants.
