The highest leaf area (23.46 cm2) was recorded in cv. Chinese Sandy Pear on BA-29, while it was minimum (14.19 cm2) in cv. Abate Fetel on BA-29. Leaf chlorophyll content was highest (3.71 mg/g) in Chinese Sandy Pear grafted on Quince. Length (27.11 μm) and width (9.96 μm) of stomata were recorded maximum in cv.

Grafted saplings of cv. Abate Fetel on Quince , cv. Chinese Sandy Pear on BA 29 and cv. William Bartlett on Quince C rootstocks recorded 86.67 per cent survival compared to other grafts. More number of saleable plants was recorded when cv. William Bartlett was grafted on Quince (86.33%). The investigations concluded that pear varieties raised on Quince rootstock had higher values for all studied parameters, followed by Quince C rootstock.","PeriodicalId":13449,"journal":{"name":"Indian Journal of Horticulture","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78807105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maintenance of this form of male sterility through conventionalmethods is a highly labour-intensive and costly task. Hence, we have developed a viable in vitro regenerationprotocol for rapid multiplication in three apetalous male sterile lines of marigold, MS-5, MS-7, and MS-8. Theeffect of Thidiazuron (TDZ) was assessed on in vitro establishment of apetalous male sterile lines using shoottipexplants. The modified MSm medium supplemented with 1.5 mg/l TDZ and 0.2 mg/l NAA was found suitablefor culture establishment from shoot tip explants. We have also assessed the efficiency of two cytokinins,TDZ and Kinetin (KIN), for rapid multiplication of male sterile lines of marigold. The culture media, genotypesand their interactions significantly influenced the shoot proliferation of marigold. Our findings have revealedthe superiority of kinetin over TDZ in inducing quality shoots during in vitro proliferation phase. The highestproliferation of quality shoots was obtained on modified MSm medium enriched with 0.5 mg/l kinetin and 0.1mg/l NAA. Half-strength MS medium supplemented with 0.5 mg/l of IBA was found effective for the inductionof quality roots in all the tested genotypes of marigold.

In this study, we attempted to induce variability in polyembryonic mango genotypes, Bappakkai,Nekkare and Kurukkan by treating their kernels with different doses of gamma rays ranging from 15 to 35 Gy.The results revealed delayed germination and a decrease in germination percentage with increasing dosageof gamma irradiation. The lethal dose (LD50) values for gamma radiation were determined, based on the seedgermination percentage using Probit analysis values, which were 22.39 Gy, 19.95 Gy, and 19.95 Gy for Bappakai,Nekkare and Kurukkan, respectively. Other traits like the number of seedlings emerging per kernel, plant height,inter-nodal length, and the number of leaves showed a gradual decrease in their mean values with increasingirradiation dosage.

To investigate the genetic inheritanceof cucumber downy mildew disease resistance, one resistant genotype (DC-70) from India was crossed with acontrasting susceptible genotype (DC-773). The parents and their progenies were evaluated in both field andnet house conditions for downy mildew disease resistance. Field condition data were recorded 4-times from30 days until the plants die. The lower leaf surface was inoculated 20-25 days after sowing at the seedlingstage by spraying the inoculum. The proportion of infection was recorded 4-times from 8-days to 65-daysafter inoculation, and the per cent disease index and area under the disease progress curve (AUDPC) werecalculated from these proportions. Based on the PDI and AUDPC, it was established that resistance to downymildew in the genotype, DC-70 was controlled by a major gene. Additive-dominance model fits the segregationdata and the additive effect was significant.
