Description |
To study the growth pattern, flOwering and fruiting behaYiour in different varieties of mango, twemty cultiyars comprising seven from West India, four from North India and nine from South India were selected. TWo hundred basic terminals were tagged raQdomly after harvest of the crop in the month of June for aUbsequent monitoring for a period of three years. The behaTiour of theae shoots in respect of linear growth, girth and number of leayes produced on each shoot durin~ each flush of differentiated and undifferentiated normal and extended shoots was s'fhe floweriD9 aDd fruiting behaviour of the differentiated shoots was Btudied for per oent flo_riD9 aDd 'fruiting paniolea, fruit set, fruit drop aDd fruit retention BO as to understand the bearing behaviour of these oultivara. ~e proportion of vegetative shoots in the aeooDd year were hl9h in 'Rajapuri', 'Khandeshi Boraaio', 'Alphonso', 'Banarasi Langra', Calcutta Lan9ra' and 'Badami Vashi'. SUoh type of shoots were relatively less in most of the Sou~~ Indian varieties. ~e ~ent of normal shoots vas higher than their exteDded oounterparts in 'Rajapuri', 'Khandeshi Borasio', (Alphonso', 'Vanraj', 'Calcutta Langra', 'Fazli', 'Ba.samt Vuhi' aDd 'Yakut Rumani'. The vegetative 9rovth of normal as well as extended shoots was higher during March, September and Ootober in most of the varietiea under study. ~e teDdenoy of shoots to grew vegetatively fro. September to ~ecember and differentiate into flower b1I4 ill the following January i. e ., having short quiBcent period was much pronounced in most of the SOUth Indian varieties particularly 'Neelum', Badami Model' aDd 'TOtapurJ.' and to a , certain extent in 'Keaar' of the weQrn India. !be proportion of shoots initiating vegetative growth in the first year and flowerlng ln the second year was high in 'Alphonso', ,Dadamio', 'Banganpalli Blg' and 'M\llgO&' • 'lbe flowered shoots of flrst year which remained Y8getative in the second year were hlgh in 'Vanraj', 'I1adamio' and 'Ke.ar' of Western India" low 'in 'Alphonso', 'Karanjio' and 'Raj apuri , of ~t} India and absent in all the Horth Indian varieties. Slmilarly for flowered .hootD of first year which d~fferentiated into flower buds in the second year also, were high in 'Vanraj' and MUlgoa' only. Such type of shoots ,were not recorded in any of the North Indian varieties. The relative proportion of monitored shoots in respegt of either differentiating into flower bud or r_cdning vegetative d1m1nished in the s~sequent year giving an indication of cyclic growth pattern. 'lbe extent of perfect flower was relatively high in 'Dadamio'. 'Rajapuri', 'Vanraj', 'Banarasi Langra', 'Calcutta Langra', 'Badami Vashi', 'Badami MOdel' and 'Neelum' yarieties. The proportion of perfect flowers vas higher in the upper one third part of the panicle. The fruit set per panicle was higher in 'Dadamlo' , 'lChandeaM Boruio'. ' Safeda '. 'Badami Vashl', ' Rumani ' and 'Reelam' varieties. The rate of fruit drop assessed afur a"aiDing the 'III&mle' stage was quite high in the 1a1tial three ve!k~ll the varieties under study. 'lbe study thus pOinted out that it was not only the iDi.iation of vegetative and reproductive growth and its pattern. but a number of inter related factors such .s proportion of shoots flowering in the first year and also in the subsequent years coupled with moderate vegetative growth. proportion of flowering and fruiting paDicles. fruit set, fruit drop and fruit retenti,on till maturity are important in confirming the regular bearing behaviour of the mango varieties. OUt of the 14 mango F1 hybrids evaluated for their tree. ,leaf. flotrer and fruit characteristics, two hybrids viz., Mee1um x Alphonso stock-27 and Neelum x Kesar stock-29 were very promising • A wide genetiC vari.tion alongwith appreciable he~ero6is was obse rved in the parental as well aB hybrid combinations |
