Research paper thumbnail of Estimation of Genetic Divergence in Apple (Malus x domestica Borkh.)

Indian Journal of Plant Genetic Resources, 2003

Genetic diversity was assessed in twenty-five apple genotypes on the basis of twenty characters. ... more Genetic diversity was assessed in twenty-five apple genotypes on the basis of twenty characters. These genotypes were grouped into four clusters on the basis of relative magnitude of D2 values using Tocher's method. Cluster I was the largest with twenty genotypes followed by cluster II consisting of three genotypes. The inter-cluster D value was maximum between cluster III and IV (55.46) followed by cluster I and IV (46.59). The maximum intracluster distance was in cluster II (19.10). Crossing between the genotypes belonging to cluster III and IV as well as cluster I and IV is expected to give maximum heterosis.

Yield per plant was found to be positively and significantly associated with stem girth, mean tree spread, leaf area, tree volume, total duration of flowering, days after full bloom, days between date of petal fall and date of commencement of June drop, number of flowers per unit shoot length, number of fruits per unit shoot length, fruit set 20 days after full bloom, fruit set 40 days after full bloom, final fruit before harvesting and fruit yield per unit shoot length. Path analysis revealed that the characters like final fruit number before harvesting, number of flowers per unit shoot length, tree volume and days after full bloom had high positive direct effects on yield per plant.

The Hindustani centre represents 344 species of fruits. Northeast India, meeting ground of Indo-Malayan and Indo-Chinese bio-geographical areas is one of the 18 mega-biodiversity centers of the World, has contributed the fruit genera like Citrus, Musa, Mangifera, Docynia, Elaeocarpus, Myrica, Morus, Artocarpus, etc. There are a quite large number of indigenous and underutilized fruit crops, which are being used by the local inhabitants in rural areas. These underutilized fruits are fairly rich in vitamins, minerals, antioxidant properties and are serving as protective food. Because of their curative properties, different parts of these fruit and plants have been used in ethno-medicines. Apart from their nutritive and medicinal values quite a few of these underutilized fruits have good flavor, colour and juice content and can be used for value additions. Several underutilized fruit species which have potential for commercial e...

Las practicas agricolas del Estado son las tradicionales, es decir agricultura migratoria, cultivos terrazados en las laderas de las colinas y arrozales anegadizos en las tierras llanas. Predominan los cereales, hortalizas, tuberculos y frutales. Debido en parte a las creencias etnicas tradicionales prevalece el empleo de germoplasma nativo para los cultivos. A la luz de esta situacion ecologica se ha tratado de recoger germoplasma nativo de los cultivos en tres distritos centrales de Meghalaya, donde se visitaron 44 sitios. Para los cultivos horticolas se adoptaron metodos de muestreo individual y selectivo, mientras que para los otros cultivos agricolas se recogieron muestras aleatorias y a granel. Los principales objetivos eran los cultivares primitivos y las variedades locales de cultivos. Se...

Fruits are a major source of nutrients such as fiber, minerals, vitamins and many phyto-chemicals that are good for preventing diseases (Deb, 1998). Mankind has been endowed with varieties of fruits, but only few gained popularity, considered nutritious and are being traded extensively. The fruits of endemic nature, which are wild, semi wild and underutilized due to lack of wider popularity but consumed with galore by the local inhabitants can also play an important role as food supplement. These fruits are known to possess all these essential elements like vitamins, minerals and polyphenols, etc. to compete with popular fruits. The antioxidant capacity of minor fruits may be comparable or even superior to that of International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 10 Number 01 (2021) Journal home...

Field diagnostic visits, regular surveys, farmer meetings and training programmes ensured application of balanced and optimum doses of nutrients and timely plant protection measures. These activities ensured higher yield over local practice of cultivation in the range of 26.5-39.4 per cent. An average net profit of Rs 3,05,302 was recorded under recommended practice while it was Rs 1,27,071.3 under farmers’ practice. Benefit/cost ratio ranged from 3.2 to 4.1 under demonstration while it ranged from 2.1 to 3.1 under control plots. With frontline demonstration (FLD) of proven technology it could be shown that yield potential and net income from turmeric cultivation could be enhanced to a great extent resulting in higher income to the f...

This region holds 17 species, out of which 8 are indigenous to this region. Despite of being a natural home and possessing wide diversity of Citrus species, none of these states, Citrus production and productivity figures could make a significant impact on the national average of Citrus production. In this review work, the occurrence, distribution; their economic importance, problems and prospects of the Citrus cultivation in this region have been discussed.

These exploration trips concerted in East, West and Upper Siang districts of eastern part of Arunachal Pradesh. These explorations were conducted in a way keeping in view of the period of maturity and harvest of collected germplasm. These trips were yielded a total of 553 different crop germplasm collected from 49 different sites with an altitudinal variation between 183 to 1100 m above msl. The crop group wise break-up of collections is cereal (188), pseudocereals (51), grain legumes (78), vegetables (86), oilseeds crop (21), spices (66), tuber crop (22), fruit crops (38) and other crops (03). Local indigenous technical knowledge practiced by the farmers on some crops was also recorded during exploration. Extents of diversity with in the collected accessions have been summarized in this paper.
