Molecular-agronomic characterization and genetic study reveals usefulness of refined Ogura cytoplasm based CMS lines in hybrid breeding of cauliflower (Brassica oleracea var. botrytis L.)

The research was conducted at Beltari Sandhikharka-10, Arghakhanchi district to study about the effect of various doses of boron on growth and yield attributing characters of cauliflower (Brassica oleracea var. botrytis) during off-season from February to June in 2020. Five treatments; B0 (control/no application), B1: 2kg/ha, B2: 4kg/ha, B3: 6kg/ha, B4: 8kg/ha which are the different doses of boron application were laid out in Randomized Complete Block Design (RCBD) with 4 replications. The growth parameters like plant height, number of leaves per plant leaf length and leaf breadth of largest leaf were recorded multiple times with 15 days interval. Days to curd initiation and Days from curd initiation to harvest were recorded by regular field observation. The yield parameters; curd weight with leaves, Marketable curd weight, average curd yield, incidence of hollowing were recorded during harvest. The economics from application of boron doses in cauliflower production was obtained in terms of cost of cultivation, gross returns, net returns, and benefit cost ratio. The result showed that the growth and yield attributing characters of cauliflower were significantly affected by application of boron in which the value of these parameters was found significantly higher in B1 followed by other treatments. The average curd yield of cauliflower in B1 was found to be 12.39 mt/ha which was 48.92% higher than that of B0 with curd yield 8.32 mt/ha. Similarly, the net return was found significantly the highest in B1 and the lowest in B0. The result showed that application of boron in the range of 2-4 kg/ha is preferred to control and higher doses in respect of both productivity and economics.

High Yielding Varieties

Hybrid breeding of watermelon has led to the formation of high-yielding varieties. The objectives of the research were to determine the performance of hybrid watermelon of the Indonesian Tropical Fruit Research Institute (ITFRI) collection and to evaluate the superiority of each hybrid. The research has been conducted at Sumani Experimental Garden, ITFRI, Solok, West Sumatera, from April to July 2016. The material used consisted of 19 cross combinations. The data from this descriptive study were presented in the form of averages and pictures. The results showed that the hybrids that were tested showed diversity in size, fruit skin color, flesh color, skin thickness and fruit sweetness. Hybrids with three excellent characters, i.e. medium fruit weight, high total soluble solids (TSS) value, and moderate rind thickness, were not yet obtained. Hybrids that had the superiority in term of sweet taste and shelf life were BT1 × SGP, BT4 × BT4P, BT5 × BT4, BT6 × SGP and SGP × BT6. Keywords: hybrid, performance, total soluble solids, watermelon ABSTRAK Pemuliaan hibrida pada semangka mengarah kepada pembentukan varietas berdaya hasil tinggi. Penelitian bertujuan untuk mengetahui keragaan hibrida semangka koleksi Balitbu Tropika dan untuk mengevaluasi keunggulan masing-masing hibrida Penelitian dilaksanakan di Kebun Percobaan Sumani, Balitbu Tropika, Solok, Sumatera Barat, dari bulan April sampai dengan Juli 2016. Materi yang digunakan terdiri dari 19 kombinasi persilangan. Data hasil penelitian deskriptif ini ditampilkan dalam bentuk rataan dan gambar. Hasil penelitian menunjukkan bahwa hibrida yang diuji memiliki keragaman dalam ukuran, warna kulit buah, warna daging buah, ketebalan kulit buah dan kemanisan. Belum ditemukan hibrida yang memiliki tiga karakter unggul, yang terdiri dari bobot buah sedang, total padatan terlarut (total soluble solid) tinggi, dan kulit buah agak tebal. Hibrida yang memiliki keunggulan berupa rasa manis dan tahan simpan adalah BT1 × SGP, BT4 × BT4P, BT5 × BT4, BT6 × SGP dan SGP × BT6. Kata kunci: hibrida, keragaan, semangka, total padatan terlarut
