CONVENOIONAL METNONS OR PROPAGATION
Pandey and Sharma (1976) reported from Allahabad that the best stock-scion combination was R. niultiflont and R. hybrid a cc. "Montezuma". Singh (1972-74) at Saharanpur, U. P. also noticed better performance of R. and tiflora rootstock. Singh (1977) further reported that R. niosoliata and R. nailti,t1ora were superior to both strains of R. bourboniana (Local and Meerut). In Bangalore, Mukhopadhyay and Banker (1982) studied the comparative performance of a thorn less rootstock as agaiut R. /nu I f (Fern and R. dice. It was reported that the largest flower were resulted when en. "Happiness" was budded either on "Thornless" or R. multi/lora. Gowda (1992) observed in Bangalore, that among the rootstocks R. multi/. lora preformed better followed by R. indica and R. Knerboniana over R. canine and R. laza.
In Scotland, Dick (1972), recommended that in heavy clay soil the use of R. ?miltiflora under stock seems to give best results since vigorous maidens with greatest performance were obtained and stock can be budded over a long period and it does not sucker. As an alternative, R. lose elm does well on a heavy clay soil that W adequately moist, however, the bushes produced are not so vigorous and have fewer blooms. Ordinary R. canine can Oct be recommended owing lathe inferior quality of the bushes, but several of its variants give better results with "Pfander's Canine' probably the most satisfactory. For standard either R. ragosa or "Pfander's Canine" can be recommended.
According to Roy Genders (1965) R. =hill are in greater use than any other form of rootstock, tend to be dwarfing M types of plants they produced. It is best understock for heavy soils and for cool conditions. R. rabiginosa is a valuable rootstock as it greatly extends the budding season, it is free from diseases and form a vigorous top growth, while its roots possess the same vigor. R. nose "Boskoop" stock of the Boskoop district of Holland is middy used for budding of standard roses and is specially suited to the roses for forcing under glass. R. inullifiora japonica, a thornless form of R. tnaltillora is unstable for use in the standard fora/ as the stem is usually too thin and brittle-iris however best for a light, sandy soil which will quickly dry out. Again both R. mill/lora and "Pollmerianestock produced plants which gave 2515 longer flowering season than any of the other rootstock. &hmidt's is also a free/flowering rootstock but suckers badly. Rasa manetti is seriously damaged by frost. P. Morale major is able to tolerate the very warm conditions, extreme heat and dry soil conditions.
Norman (1958) studied that garden roses will grow on the roots of any of the Rosa species, but only a few kinds will guarantee that the resulting plants will have a long life. Rosa mina is one of the stocks generally favored by commercial growers, usually in the form of seedlings, but sometimes grown front cuttings, and long stem obtained from hedgerows are used for standard. Rosa imilliflora both seedling and cuttings is preferred by nurserymen whose soil is light. It. rupee is mostly used as stems for standard. R. taxa seedlings and cuttings are very similar in habit tall. mina, but practically thorniest and no preferred by budders on that account.
Yadav et. al., (1989) enumerated the qualities of different rootstocks and noted that It bomber:lane is hardy, vigorous, easily propagated, grow straight and useful for budding standards. R. canine commonly used as rootstock in Europe in which buds are difficult to germinate and cuttings do not root easily, difficult to handle for existence of prominent.
